Image Compressor
Make images smaller with a quality slider you control.
Image Compressor re-encodes JPEG, PNG and WebP files at a quality level you choose, showing the new size and a side-by-side preview before you download. Compression runs on a canvas in your browser, so the photo is never uploaded — and you can compress a hundred files in one batch.

Questions about Image Compressor
Which quality setting should I use?
For photos on the web, 75-82% is the sweet spot: typically 60-80% smaller than the original with differences you have to look for. Below 60% you start seeing blocking around edges and in smooth gradients like skies.
Is compression lossless?
JPEG and WebP compression here is lossy — pixels are approximated to save space. PNG output stays lossless, so PNG savings come from re-encoding rather than from discarding detail. Choose WebP if you want the best ratio at a given visual quality.
Does it remove EXIF data?
Yes, as a side effect. Redrawing through a canvas discards all metadata, including GPS coordinates. If that is your actual goal, Remove EXIF is the direct tool.
Is there a limit on file size or on how many images?
No limit is imposed by the tool — the ceiling is your device's memory. A hundred ordinary phone photos is routine on a laptop. Very large images, above roughly 100 megapixels, can fail to decode on a phone, and the page reports that rather than hanging.
Is it safe to compress confidential photos here?
The image is decoded and redrawn inside the page, and there is no upload endpoint on this site to send it to. You can check that yourself: open the browser network panel while you compress, or disconnect from the internet and watch the page keep working.
Is Image Compressor really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use Image Compressor?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
