Compress Image
Make JPEG, PNG, WebP and HEIC images smaller right in your browser.
Drop images here or paste from the clipboard
JPEG, PNG, WebP and HEIC. Add as many as you like.
Files stay on this device. Nothing is uploaded.
How to use
Drop images onto the box, choose them with the button, or paste a copied image. You can add many files at once, and each one is compressed as soon as it arrives.
Pick the output format. Original keeps each file's format, except HEIC, which becomes JPEG. WebP usually gives the smallest files, and JPEG opens everywhere.
Move the quality slider to trade size for detail. Set a max width or height to shrink large photos too. After changing a setting, press Apply new settings to compress the files again.
Check the size before and after for each file, then download them one by one or all at once. If a compressed copy turns out larger than the original, the original is kept and marked.
FAQ
Are my images uploaded to a server?
No. Your browser decodes and re-encodes the images on your device, and the files are never sent anywhere. The network panel of your browser's developer tools shows that no request carries your images.
Is there a limit on file size or the number of images?
There is no fixed limit. Images are processed one at a time, so the practical limit is your device's memory. On iPhone and iPad, images larger than about 16.7 megapixels are scaled down to fit Safari's canvas limit.
Why did my PNG get bigger or stay the same?
PNG is lossless, so the quality slider cannot remove detail from it, and re-saving a PNG that was already optimized often makes it larger. In that case the original is kept. Choose WebP or JPEG for a much smaller file. JPEG has no transparency, so transparent areas turn white.
Does compressing remove EXIF data and GPS location?
Yes. Re-encoded images do not carry EXIF metadata, so camera details and location are removed. Photos are turned upright first, so they still display the right way. When the original is kept because it was smaller, its metadata stays as it was.
Does it work on iPhone and Android?
Yes. It runs in mobile browsers such as Safari on iPhone and Chrome on Android, and HEIC photos from an iPhone are saved as JPEG. Some browsers cannot save WebP; the tool shows an error for those files and you can pick JPEG instead.
