Two ways to find a tool
Some people know the exact tool they want and go straight to it. Others know the kind of thing they are working with — an image, a PDF, a spreadsheet — but not which tool does the job. Categories are for the second group. Each one gathers every tool that works on a particular kind of file, so you can start from what you have rather than from a name you would have to guess.
The cards above are ordered by how many tools sit inside each, and every count is live — it reflects exactly what is published right now, never a number typed in by hand. A category only appears once it has at least one tool, so nothing here leads to an empty page. As the library grows, categories fill out and new ones appear on their own.
What the categories mean
- Image — converting between formats, shrinking file size, and changing images so they open and load where you need them.
- PDF — turning files into PDFs and reshaping PDFs into what a form, an inbox or a printer will accept.
- Data — the small, fiddly jobs on spreadsheets and structured files that are tedious to do by hand.
- Code — utilities for the everyday tasks around markup, config and text that developers hit constantly.
- Video — handling and converting video files without wrestling desktop software.
Not every category is filled yet, and that is deliberate — a category shows up only when there is a real tool behind it, so the page never promises something it cannot deliver. If a category you expected is missing, its tools simply have not been built yet.
However you got here
Whichever category you open, the tools inside follow the same rules as the rest of the site: free to use, no account, and run in your browser rather than on a server, so your files never leave your device. Pick a category to narrow things down, or open the full tool library if you would rather see everything on one list and filter it yourself.
Missing a tool, whatever category it would belong to? The request form on the tools page is the way to ask — the job people request most is the one built next.
How are the tools organised into categories?
Each category groups tools by the kind of file they work on — Image, PDF, Data, Code, Video. Every tool is filed under the category that matches what it handles, so you can find one by starting from what you have rather than from its name.
Why do some categories not appear?
A category only shows once it has at least one published tool behind it. Empty categories are hidden on purpose, so nothing on this page leads to a blank list. As new tools are added, the categories they belong to appear automatically.
Are the tool counts accurate?
Yes. Every count is pulled live from what is published at that moment, not typed in by hand, so the number on each card always matches the number of tools you will find inside it.
Do I have to use categories to find a tool?
No. Categories are one route; the full tool library is the other. The library puts every tool on a single page with a search and filter, so if you would rather scan everything at once and narrow it down yourself, start there instead.
Missing something, or found something broken?
Request a tool
The format you have, the format you need, and what usually goes wrong. Read every Monday; most-asked gets built first.

Name the tool and the file type, then what you expected. It goes straight to whoever wrote that tool.
