Compress Image (JPG, PNG & WebP) SMALLER FILES
Drop images to shrink their file size — pick a quality level or a target size. Everything stays in your browser.

Quality
Target size
The default (80%) keeps images looking sharp — hit Compare on any file to check quality before you download. WebP usually compresses best; PNG stays lossless (colours are reduced to shrink it). Target size finds the best quality that fits.
Files are converted in your browser and never uploaded.

How to use it
Compress Image
Compress Image
in three moves.
01
Add your images
Drop one file or forty onto the panel, or browse for them. They are read straight off your disk — there is no upload bar because there is no upload.
02
Choose quality, or a target size
The 80% default is the safe setting for photos. Switch to target size when something imposes a hard ceiling — an upload form, an email attachment, a job portal.
03
Compare, then download
Compare puts the original and the result side by side at full zoom. If it looks right, download the file or the whole batch and close the tab.
Formats & limits
What goes in, what comes out.
| Input | Output | Typical saving | Best for |
|---|---|---|---|
| jpg / jpeg | jpg | 40–70% | Photographs that must stay widely compatible |
| png | png | 20–50% | Screenshots, logos and flat colour with transparency |
| png / jpg | webp | 55–80% | Anything going on a website — smallest at equal quality |
| webp | webp | 15–40% | Re-compressing an already-modern file further |
Why this one
Built against the ways these tools disappoint.
We ran the same files through the popular alternatives first. These are the gaps we found, and what this tool does instead.
01
Most compressors cap the free tier at 5 MB or twenty files.
A limit that exists to sell a subscription, not because the work is costly. Nothing here is metered — your machine does the compressing.
test: drop forty photos at once
02
You only see the damage after you download.
Compare shows original and result side by side at full zoom, before anything leaves the page.
test: compress one photo and hit Compare
03
Compress to 200 KB" usually means one blind guess.
Target-size mode searches for the highest quality that still fits under your limit, rather than dropping to a fixed low setting.
test: set a 200 KB target on a large photo
The detail
How this actually works.
Most compressors hand you a quality slider and let you guess. That’s fine until something imposes a hard ceiling — an upload form capped at 200 KB, a job portal that rejects anything over 1 MB, an email limit. Then guessing means compress, check, adjust, repeat.
Target-size mode solves that: enter the KB or MB you need, and the tool searches for the highest quality that still fits underneath it — one pass, no guessing. Or stay on the quality slider when you just want a smaller file without a fixed limit.
It works on JPG, PNG and WebP, and you can keep the original format or convert on the way out. WebP usually gives the smallest file at the same quality; PNG stays lossless. Whatever you pick, Compare shows the original and result side by side at full zoom, so you approve the quality before you download — nothing leaves your browser at any point.
Converting instead of just shrinking? JPG to WebP, PNG to WebP and AVIF to WebP use the same engine, and the format field guide helps you choose which format to keep.
You don’t need Photoshop, MS Paint, Mac Preview, or a phone app — the three methods Google usually lists. This runs entirely in your browser on any device: drop the image, set a quality level or a target KB size, and Compare shows the original and result side by side at full zoom before you download. It works on JPG, PNG and WebP, keeps the original format or converts on the way out, and nothing is ever uploaded.
FAQ
The questions people actually type in.
Are my images uploaded to a server?
No. Compression runs inside your browser using your own machine. You can check in the network tab, or turn your wifi off after the page loads and compress anyway.
How do I compress an image to a specific size, like 200 KB?
Switch "Compress by" to Target file size and enter your limit. The tool searches for the highest quality that still fits underneath it, rather than guessing a quality level and overshooting.
Does compressing an image reduce its quality?
JPG and WebP discard some data, so technically yes — but at the default 80% the difference is normally invisible at ordinary viewing size. PNG is handled differently: the file shrinks by reducing the colour palette rather than softening pixels. Either way, Compare shows you both side by side before you download.
Which format compresses best?
WebP, usually by a wide margin — roughly 25–35% smaller than JPG at matched quality, with transparency support. Keep JPG or PNG if the file is going somewhere outside a browser, like a printer or older desktop software.
Is there a limit on how many images I can compress?
No file-count limit and no queue. The practical ceiling is the memory your browser can use, comfortably tens of megabytes on a laptop.
How do I reduce an image to a specific size like 200 KB?
Switch "Compress by" to Target file size, type your limit in KB (e.g. 200), and the tool searches for the highest quality that still fits underneath — no guessing with a slider. It works right in your browser, so nothing is uploaded. Hit Compare to confirm the quality before you download.
How do I compress an image without any software or app?
You don't need Photoshop, Paint, or a phone app. This runs in your browser: drop the image, pick a quality level or a target KB size, compare, and download. Everything happens on your device — the file is never uploaded.
How do I make a photo smaller on iPhone or Android?
Open this page in your phone's browser, add the photo, and choose a target size or quality — no app install. The result downloads straight to your device, and nothing leaves your phone.
