Shrink JPG and WebP photos with a simple quality slider — and see the exact before/after file size for every image. All in your browser, nothing uploaded.
No images selected
Lower = smaller file. 80% looks identical to most eyes.
A 4 MB phone photo can become 300 KB at 80% quality — your pages load in a blink and visitors stay.
Beat the 25 MB attachment limit by compressing photo sets before sending.
Compressed images upload faster on slow connections and use less mobile data.
Keep visually identical copies of your photo library at a tenth of the disk space.
80% is the sweet spot for photos on the web — visibly identical to the original at a fraction of the size. Use 60–70% for thumbnails and previews, 90%+ when quality matters most.
WebP gives smaller files at the same quality and is supported by all modern browsers. Choose JPG for maximum compatibility with older software.
PNG is a lossless format, so the quality slider doesn't apply to it — PNG output is always full quality. For smaller files, compress to JPG or WebP instead.
No. Compression runs entirely in your browser using the canvas API. Your photos never leave your device.
