Shrink JPG, PNG and WebP file sizes, resize dimensions, and convert between formats — all in your browser. Nothing is uploaded.
Compress images online for free — reduce the file size of your JPG, PNG and WebP photos so they upload faster, fit email limits, and load quickly on your website. You can also resize the dimensions and convert between formats (like PNG to JPG or JPG to WebP). Everything runs in your browser, so your images stay 100% private.
Drop your photos above, pick an output format and a quality level (70–85% keeps images looking sharp while cutting most of the size), optionally set a max width to resize, then click Compress and download. It works on phone and desktop.
No. Everything happens locally in your browser — your images never leave your device, so it's completely private.
Keep the quality slider around 70–85%. That removes most of the file size while keeping the image visually identical.
JPG, PNG and WebP — for both input and output. Convert PNG→JPG to shrink screenshots, or JPG→WebP for the smallest files.
