Generated by Rank Math SEO, this is an llms.txt file designed to help LLMs better understand and index this website. # ToolsVale ## Sitemaps - [XML Sitemap](https://toolsvale.com/sitemap_index.xml): Includes all crawlable and indexable pages. ## Posts - [How to See All Images on Any WordPress Site](https://toolsvale.com/see-all-images-on-wordpress-site/): In this guide you will learn how to see all images on a WordPress site in four simple ways. If you own a site, you will also learn how to hide your own list in about five minutes. - [How to Detect AI Writing on a Website: A Complete Guide](https://toolsvale.com/how-to-detect-ai-writing-in-a-website/): Learning how to detect AI writing in a website can help website owners, SEO professionals, editors, and publishers make more informed decisions about their content. AI detectors offer a useful starting point, while manual review helps identify generic writing, unsupported claims, repetitive explanations, and missing expertise. - [How to Find Broken Links on a Website: Complete Guide](https://toolsvale.com/how-to-find-broken-links/): This guide explains how to find broken links on a website, how to understand different HTTP status codes, how to identify the page containing a broken link, how to fix common link problems, and how to verify that the problem is actually resolved. - [What Are Open Graph Tags? Complete OG Meta Tags Guide](https://toolsvale.com/open-graph-tags-guide/): When someone drops your link into Slack, LinkedIn, or a WhatsApp group, the preview card that appears — title, image, description — isn't pulled from thin air. It's read directly from Open Graph tags in your page's HTML. Get them right and your link looks polished, branded, clickable. Get them wrong — or skip them entirely — and your URL shows up as a bare text link with a broken thumbnail that nobody clicks. - [How to Extract High-Resolution Frames from 4K Video](https://toolsvale.com/extract-high-resolution-frames-from-4k-video/): You shot a gorgeous 4K video — 3840×2160 pixels, crisp detail, perfect lighting. Now you need a still image from it. You pause the video, take a screenshot, and the result looks soft, pixelated, and nothing like what you saw on screen. - [How to Detect AI-Generated Content](https://toolsvale.com/how-to-detect-ai-generated-content/): AI-generated text is everywhere — blog posts, essays, product descriptions, guest articles, even academic submissions. Whether you are an editor reviewing freelance drafts, a teacher grading assignments, or an SEO professional auditing website content, knowing how to detect AI-generated content is no longer optional. It is a core skill. - [How to Extract Frames from Video Online](https://toolsvale.com/how-to-extract-frames-from-video-online/): Every video file is a sequence of still images played fast enough to look like motion. A 10-second clip at 30 fps contains 300 individual frames. Sometimes you need one or more of those frames as a standalone image — a thumbnail for YouTube, a reference still for a storyboard, a training image for a machine learning dataset, or proof of what happened at a specific moment in dashcam footage. - [How to Find & Fix Keyword Cannibalization Guide](https://toolsvale.com/keyword-cannibalization-guide/): For a quick, no-signup alternative, you can use a free keyword cannibalization checker that analyzes SERP similarity between keywords to flag overlapping intent before it becomes a ranking problem. - [How to Audit Canonical Tags](https://toolsvale.com/how-to-audit-canonical-tags/): Reading time: 14 min - [How to Convert HEIC to JPG Without Losing Quality](https://toolsvale.com/how-to-convert-heic-to-jpg-without-losing-quality/): Convert HEIC to JPG at quality 90 — no visible loss. 6 methods compared: browser-based (no upload), iPhone settings, Mac, Windows, CLI, and cloud. - [Free Sitemap Tools Compared](https://toolsvale.com/sitemap-tools-toolsvale-vs-xml-sitemaps-vs-seo-ai/): ToolsVale launched in August 2026 — barely a month old at the time of this comparison. It ships three separate sitemap tools: a sitemap generator, a sitemap validator with AI crawler auditing, and a sitemap duplicate content scanner that compares page content across every URL in the sitemap. The tools are free with no signup required. - [Free Online Converter Privacy](https://toolsvale.com/privacy-risks-free-online-converters/): On March 7, 2025, the FBI Denver Field Office published an advisory about free online document converter tools being used to distribute malware. The warning was specific: criminals were creating websites that mimicked legitimate file converters — PDF to DOCX, JPG to PNG, MP4 to MP3 — and the tools worked as advertised. The file got converted. But the output also contained embedded malware, and the uploaded file was scraped for passwords, banking details, and cryptocurrency wallet information. - [Best Sitemap Validator 2026: 7 Tools Tested on the Same Sitemap](https://toolsvale.com/best-sitemap-validator/): Most "best sitemap validator" lists compare feature tables pulled from marketing pages. Nobody runs the same sitemap through every tool and checks what each one actually catches. - [XML Sitemap Guide 2026: Create, Validate & Fix Sitemap](https://toolsvale.com/xml-sitemap-guide/): Most "how to create a sitemap" guides stop at "click generate, upload the file." That gets you a sitemap. It does not get you a sitemap Google trusts, and it will not tell you when the one you already have is quietly costing you crawl budget — which, for most sites reading this, is the more common problem. - [Soft 404 vs Hard 404: How to Audit & Fix Redirect Chains](https://toolsvale.com/soft-404-vs-hard-404/): Google Search Console flags "Soft 404" and "Not found (404)" as separate issues — because they are. One wastes your crawl budget silently. The other loses your link equity visibly. And redirect chains compound both. Here's how to diagnose and fix all three. - [AI Crawlers & robots.txt GPTBot, ClaudeBot & More](https://toolsvale.com/ai-crawlers-robots-txt-guide/): AI bots now account for over 20% of verified bot traffic on the web. The biggest shift: every major AI provider has split its crawlers into separate bots for training, search, and real-time user requests — and each one needs its own robots.txt rule. Here's the complete reference. - [Broken Link Statistics: 55+ Facts About Link Rot, 404 Errors & Dead Backlinks](https://toolsvale.com/broken-link-statistics/): How fast does the web break? Every major study — from Pew Research to Ahrefs to Harvard Law Review — tells the same story: links die faster than most people assume, and the consequences for SEO, usability, and trust are measurable. - [Bulk HEIC to JPG Converter Online – Convert Large Batches Without Crashing Free](https://toolsvale.com/bulk-heic-to-jpg-converter-online/): Multiply that by 100–500 photos from a single iPhone backup, and you're asking the browser tab to hold several gigabytes of decoded image data in memory at once. Chrome and Safari both cap tab memory, and when a page exceeds it, the tab doesn't slow down gracefully — it crashes outright, usually right before the ZIP file finishes generating. That's the exact failure point most users hit, and it's why "bulk heic converter" searches are full of people asking why their batch died at 80%. - [Why Your SVGs Are Too Big — How to Optimize SVG File Size](https://toolsvale.com/svg-optimization-file-size-guide/): An SVG exported from Figma or Illustrator carries metadata, editor cruft, and precision you do not need. Here is what to strip, what to keep, and how much smaller the file gets. - [Screaming Frog vs Toolsvale Broken Link Checker Comparison](https://toolsvale.com/screaming-frog-vs-toolsvale-broken-link-checker/): You're here for one of two reasons. Either Screaming Frog just told you "500 URLs" and stopped, or you're about to install a desktop app just to check whether a client's site has dead links, and something about that feels like overkill. Both are good reasons. Here's the honest comparison — including where Screaming Frog is flatly the better tool, because it usually is for the deeper job. - [Best Content Cannibalization and Internal Duplicate Content Checker](https://toolsvale.com/best-content-cannibalization-checker/): A content cannibalization checker is what you reach for when two pages on your own site start competing for the same keyword instead of one page winning it — and almost every tool built for that job makes you trade something to get it. - [Why Most Free Bulk URL Status Code Checkers Fail](https://toolsvale.com/best-bulk-url-status-code-checker/): The problem isn't finding a tool to do this; it's finding a free tool that actually finishes the job. We built our own Bulk URL Status Code Checker because the existing options routinely frustrated us. They either cap out too early, hide vital redirect hops, or miss soft-404s completely. - [What a 404 error actually is — and the four ways to fix one](https://toolsvale.com/what-is-a-404-error/): A 404 means the server was reachable and working, but could not find the thing you asked for. That is all it means. It is not a penalty, not a sign your site is broken, and — this is the part most guides get wrong — not always something you should fix. - [llms.txt: what it is, and whether you actually need one](https://toolsvale.com/llms-txt-explained/): Google Search says llms.txt has no effect on your rankings. Chrome's Lighthouse runs an audit that checks for it. Both are true, they are not in conflict, and the confusion between them is why this file has been argued about for eighteen months without anyone explaining how to write one properly. - [Best Broken Link Checker: 11 Tools Tested on the Same 3 Sites](https://toolsvale.com/best-broken-link-checker/): Most "best broken link checker" lists are written by the people who make one of the tools, and almost all of them put their own product first. This one is too — ToolsVale is ours — so we have not ranked it first, and we have written down where it loses. What follows is what each tool actually caps you at, taken from the vendors' own pages. ## Pages - [Home](https://toolsvale.com/home-2/) - [Thankyou](https://toolsvale.com/thank-you/) - [How It Works](https://toolsvale.com/how-it-works/): Every tool on ToolsVale follows the same shape, so once you have used one you have effectively used all of them. Here is exactly what happens between opening a tool and getting your result — including the part that makes this site different from most of the free tools you will find elsewhere. - [Categories](https://toolsvale.com/categories/): Every tool grouped by what it works on. Pick a category to see just those tools, or jump straight to the full library — however you like to find things. - [Tools](https://toolsvale.com/tools/): Most file tasks are small. Turn this into that, make this smaller, pull these together. They do not need a dashboard, a project, an account or a subscription, and they certainly do not need you to hand a private file to a server before you can get on with your day. Every tool in this library is built for exactly one of those small jobs and nothing else. Open it, do the thing, close the tab. There is no second screen trying to sell you the rest of a suite. - [Faq](https://toolsvale.com/faq/): The questions people actually ask about ToolsVale — how the tools work, what happens to your files, and what they cost. If yours isn't here, the request form on the tools page is the fastest way to reach us. - [About Us](https://toolsvale.com/about-us/): ToolsVale exists because free online tools kept wasting our time. Not by being free — by being subtly broken in ways you only discover after the download finishes. - [How we handle files](https://toolsvale.com/how-we-handle-files/): Most of our tools never receive your file. They run inside your browser, on your own machine, so there is nothing for us to store, sell, or lose. This page explains exactly which tools work that way, which do not, and what happens in each case. - [Report a bug](https://toolsvale.com/report-a-bug/): Found a tool doing the wrong thing? Tell us and it gets fixed. Reports here go straight to whoever built that particular tool, not into a support queue — so the more precisely you describe what happened, the faster it turns into a fix. - [Contact](https://toolsvale.com/contact/): Questions, a tool that misbehaved, an idea for something we should build — this is where to send it. There's no ticket queue and no bot in the way; messages are read by the people who actually build and run ToolsVale. - [Cookies](https://toolsvale.com/cookies/): Last updated: 18 August 2026 - [Terms and Conditions](https://toolsvale.com/terms-and-conditions/): Last updated: 18 August 2026 - [Blogs](https://toolsvale.com/blogs/) - [Home](https://toolsvale.com/) - [Privacy Policy](https://toolsvale.com/privacy-policy/): Last updated: 15 August 2026 ## Tools - [WordPress Site Inspector](https://toolsvale.com/wordpress-site-inspector/): Instead of navigating through a WordPress administration panel or manually searching for individual media URLs, you can use this free WordPress media library explorer to view available files in a searchable interface. Search by filename, title, or URL, filter results by media type, preview available media, and copy direct media URLs when you find the file you need. - [Background Remover](https://toolsvale.com/background-remover/): Remove image backgrounds in your browser with an AI that never uploads your photo. Two model choices, batch processing, and the output stays on your device. - [CSV Viewer](https://toolsvale.com/csv-viewer/): Free online CSV viewer that parses, displays, and analyses CSV files entirely in the browser. Features auto-delimiter detection, header detection with manual override, column type inference, numeric statistics, sortable and searchable table output, formula injection warnings, and sanitized export. No file uploads, no server processing, no account required. - [Gemini Watermark Remover](https://toolsvale.com/gemini-watermark-remover/) - [llms.txt Validator](https://toolsvale.com/llms-txt-validator/): The best free llms.txt validator — spec compliance, dead links, Content-Type, robots.txt conflicts, and 5 AI crawler access simulation. Lighthouse 13.3 Agentic Browsing aligned. No signup, results in seconds. - [Markdown Viewer](https://toolsvale.com/markdown-viewer/): Open .md files in your browser and read them rendered. Shows document diagnostics — word count, heading structure, link health — that no other viewer provides. Everything runs on your device. - [AI Readability Checker](https://toolsvale.com/readability-checker/): The best free readability checker — 7 formulas with consensus grade, AI crawler accessibility check across GPTBot, ClaudeBot and PerplexityBot, per-paragraph heatmap and rule-specific fix suggestions. No signup, results in under 15 seconds. - [AI Content Detector](https://toolsvale.com/ai-content-detector/): Free AI content detector that analyzes pasted text or a webpage URL for patterns associated with AI-generated and AI-assisted writing. Get an explainable result with evidence and sentence-level signals. - [Sitemap Duplicate Content Scanner](https://toolsvale.com/sitemap-duplicate-content-scanner/): A free tool that scans your sitemap, compares every page's actual content, and flags near-duplicates and possible keyword cannibalization — with CSV export. - [Sitemap Validator](https://toolsvale.com/sitemap-validator/): Every free sitemap validator stops at XML syntax. This one actually fetches every URL in your sitemap as five different crawlers — Chrome, Googlebot, GPTBot, ClaudeBot, and PerplexityBot — cross-checks your robots.txt per crawler, detects your CMS to give you platform-specific fixes, and flags the tags Google actually ignores in 2026. Three scores: Schema Health, Google Compliance, AI Discoverability. Free forever, no signup, shareable 48-hour audit links. - [SEO Audit Checker](https://toolsvale.com/seo-audit-checker/): Run a free SEO and AEO audit on any URL. Checks 200+ rules across on-page SEO, AI crawler access, AI citation readiness, Core Web Vitals, and accessibility. Framework-aware fixes for WordPress, Shopify, Webflow, and more. No signup. - [Schema Validator](https://toolsvale.com/schema-validator/): The best free schema validator — checks JSON-LD, Microdata, and RDFa against schema.org v30 and Google's 2026 rules, plus content parity and 5 AI crawler visibility (Googlebot, GPTBot, ClaudeBot, PerplexityBot). No signup, results in under 15 seconds. - [Open Graph Checker](https://toolsvale.com/open-graph-checker/): The only free Open Graph checker that decodes your og:image bytes to verify real dimensions, checks all 7 major crawlers for cloaking, and enforces WhatsApp's 600KB hard cap before your preview silently breaks. - [Bulk Domain Authority Checker](https://toolsvale.com/domain-authority-checker/): Check Domain Authority, spam risk and domain age for 100 URLs at once. Every score comes with its source. No Moz account, no captcha, no signup. - [Meta Tag Checker](https://toolsvale.com/meta-tag-checker/): Analyze meta tags, preview SERP and social cards, detect cloaking, and generate optimized meta tag code — for up to 10 URLs at once. - [Markdown Front-Matter Validator and Sanitizer](https://toolsvale.com/markdown-front-matter-validator/): Front matter looks harmless — a few lines of metadata sitting above your actual content, wrapped in three dashes. But it's also one of the easiest places for a static site build to quietly break. A missing required field, an unquoted colon inside a title, a date that isn't quite ISO-8601, and your build either fails outright or, worse, publishes something wrong without telling you. This tool exists to catch those problems before they reach your build pipeline, right in your browser, for free. - [Bulk URL Status Code Checker](https://toolsvale.com/bulk-url-status-code-checker/): A single broken link is easy to spot. A hundred of them, scattered across an old sitemap, a migrated domain, or a client's redirect map, are not. That's the gap this tool is built to close: paste a list of URLs, and within seconds you get the HTTP status code, the full redirect path, response time, and any hidden issues for every single one — without opening a terminal, installing desktop software, or paying for a crawler subscription. - [Google Index Status Checker](https://toolsvale.com/google-index-status-checker/): Check whether your pages are indexed by Google and find indexing, crawling, robots.txt, canonical, and sitemap issues. - [SVG Minifier](https://toolsvale.com/svg-minifier/): Minify SVG files without uploading them. Clean editor metadata, remove unused SVG data, optimize numbers and colors, and process multiple files directly in your browser. - [Video to Frames Extractor](https://toolsvale.com/video-to-frames/): Turn any video into a set of still images without installing software or uploading anything to a server. The Video to Frames tool runs entirely inside your browser tab, reading the video file directly from your device, capturing frames on a canvas, and letting you download them individually or as a single ZIP archive. Nothing is sent anywhere, which makes it a practical choice for private footage, unreleased content, or simply anyone who doesn't want to wait on an upload and download cycle. - [Trailing Slash Checker](https://toolsvale.com/trailing-slash-checker/): Find every trailing-slash redirect and the exact internal link still causing it — not just a list of redirecting URLs. Free, runs against your whole site. - [Unix Timestamp Converter](https://toolsvale.com/timestamp-converter/): Unix timestamp converter that detects seconds, milliseconds, microseconds or nanoseconds for you, so a 13-digit value never lands you in the year 56000. - [JWT Decoder](https://toolsvale.com/jwt-decoder/): JWT decoder that runs in your browser, so your token is never uploaded. Every claim explained, the expiry counted down live, unsafe algorithms flagged. - [JSON Stringify and Unstringify](https://toolsvale.com/json-stringify/): JSON stringify and unstringify in your browser. It peels every layer of escaping, not just one, so double-escaped webhook payloads come back readable. - [JSON minifier](https://toolsvale.com/json-minifier/): JSON minifier that shows the real gzipped size, not an estimate. Invalid JSON gets the exact line, column and cause. Runs in your browser, no upload. - [URL Encoder Decoder](https://toolsvale.com/url-encoder-decoder/): Encode or decode URLs and query values free in your browser. Component, Full URL and Form modes, recursive decode, and a live URL parameter breakdown. No upload. - [Extract URLs from Text](https://toolsvale.com/extract-urls-from-text/): Extract URLs from text free — paste any email, log or HTML and pull every link into a clean list. Get URLs, domains or emails, dedupe, copy or download. - [Image Color Picker](https://toolsvale.com/image-color-picker/): Pick any color from an image and get HEX, RGB, HSL, HSV and CMYK, plus an auto palette. Magnifier and one-click copy, all in your browser — nothing uploaded. - [Rotate & Flip Image](https://toolsvale.com/rotate-image/): Rotate images 90° or 180°, straighten a crooked shot, or flip them — free and private in your browser. Batch rotate, no upload, and it fixes sideways phone photos for good. - [Crop Image](https://toolsvale.com/crop-image/): Crop image files to any ratio, a circle, or an exact pixel size — free, in your browser. Passport presets, batch crop, transparent-PNG circles. No upload, no watermark. - [Resize Image](https://toolsvale.com/resize-image/): Resize image files to any size right in your browser — by exact pixels, a percentage, or a ready-made preset, and crop them too, without uploading a thing. Resizing changes an image's width and height, and oversized photos are one of the most common causes of slow-loading pages, so getting the dimensions right matters for both speed and how your pictures look wherever you use them. This image resizer keeps the aspect ratio locked by default so nothing stretches, and shows the new dimensions and file size before you download. - [SERP Snippet Preview](https://toolsvale.com/serp-snippet-preview/): A SERP snippet preview shows exactly how your page's title, URL and meta description will appear in Google's search results before you publish. It matters because Google truncates titles and descriptions by pixel width, not character count — a title with wide letters like "W" and "M" gets cut off sooner than a narrow one of the same length. This tool measures the real rendered width in Arial, the font Google uses, and shows precisely where your text will be clipped, on both desktop and mobile. - [AVIF to PNG](https://toolsvale.com/avif-to-png/): Convert AVIF to PNG free, right in your browser — no upload. Lossless PNG keeps every pixel and transparency, ideal for editing. Batch-convert and download as a ZIP. - [AVIF to JPG](https://toolsvale.com/avif-to-jpg/): Converting AVIF to JPG turns a next-generation image into one that opens everywhere. AVIF, built on the AV1 video codec, is roughly half the size of a JPEG at the same quality, which is why so many websites and CDNs now serve their images in it. But that efficiency comes at a cost: download one and Windows Photos, older editors, email clients, upload forms and print shops often can't read a .avif file at all. JPG opens on essentially every device, app and service there is, so the conversion fixes the problem instantly and permanently. - [Broken Link Checker](https://toolsvale.com/broken-link-checker/): Free broken link checker that crawls your whole site and shows exactly which page each dead link sits on. Live results, redirects and firewall blocks flagged, CSV export. - [Schema Markup Generator](https://toolsvale.com/schema-markup-generator/): Generate clean, valid Schema.org JSON-LD for Google rich results and AI answer engines. Article, Product, FAQ, Local Business and more — empty fields dropped automatically. - [robots txt Generator](https://toolsvale.com/robots-txt-generator/): Generate a valid robots.txt free — with a warning before you accidentally block your whole site from Google. Set per-bot rules, crawl-delay and your sitemap line. - [XML Sitemap Generator](https://toolsvale.com/sitemap-generator/): Generate a valid XML sitemap free — no 500-page cap. Discover your pages or paste a list, add lastmod, and auto-split large sites into a sitemap index automatically. - [hreflang Tag Generator](https://toolsvale.com/hreflang-tag-generator/): Generate correct hreflang tags for multilingual sites — as HTML link tags or an XML sitemap block, with x-default and validation that catches the errors Google ignores. - [llms.txt Generator](https://toolsvale.com/llms-txt-generator/): Build a curated, spec-compliant llms.txt — not a sitemap dump. Help ChatGPT, Claude and Perplexity understand and cite your site. Free: discover, curate, export. - [HEIC to JPG](https://toolsvale.com/heic-to-jpg/): Convert HEIC to JPG free, right in your browser — no upload. Turn iPhone photos into JPGs that open and print anywhere, batch-convert, and download as a ZIP. - [WebP to PNG](https://toolsvale.com/webp-to-png/): Convert WebP to PNG free, in your browser — no upload. Lossless PNG keeps every pixel and transparency, ideal for editing. Batch-convert and download as a ZIP. - [WebP to JPG](https://toolsvale.com/webp-to-jpg/): Convert WebP to JPG free, right in your browser — no upload, no watermark. Batch-convert, choose the background for transparent areas, and download as a ZIP. - [HEIC to PNG](https://toolsvale.com/heic-to-png/): Convert HEIC to PNG free, in your browser — no upload. Lossless PNG keeps every pixel and transparency, perfect for editing. Batch-convert and download as a ZIP. - [PNG to WebP](https://toolsvale.com/png-to-webp/): Convert PNG to WebP free, in your browser — no upload. Transparency stays intact, files shrink 25–90%, and you see the saving before you download. Batch and ZIP. - [WebP to PDF](https://toolsvale.com/webp-to-pdf/): Convert WebP to PDF free, in your browser — no upload, no watermark. Reads WebP directly (no JPG step) and combines several into one PDF with your choice of layout. - [Image to PDF](https://toolsvale.com/image-to-pdf/): Combine JPG, PNG, WebP or HEIC images into one PDF — free, in your browser, no upload, no watermark. Choose page size, layout and order, and mix formats freely. - [AVIF to WebP](https://toolsvale.com/avif-to-webp/): Convert AVIF images to WebP free, right in your browser. No upload, no account — batch-convert, download as a ZIP, and see both file sizes before you save. - [HEIC to PDF](https://toolsvale.com/heic-to-pdf/): Convert HEIC to PDF free, right in your browser — no upload. Combine iPhone photos into one PDF with your choice of page size, layout, margins and order. - [HEIC to WebP](https://toolsvale.com/heic-to-webp/): Convert HEIC to WebP free, in your browser — no upload. Go straight from iPhone HEIC to web-ready WebP in one pass, at a quality you choose. Batch and ZIP.
