Shrink JPEG, PNG and WebP files with a live quality slider and a before/after preview. Your photos are processed right here on your device.
Add JPEG, PNG or WebP files. They're compressed right here in your browser and never uploaded.
Drop in JPEG, PNG or WebP files — one or a whole batch at once.
Drag the quality slider or nudge it with the −/+ steppers, hit Apply, and compare any image before and after.
Grab a single image, or download the whole batch as one ZIP.
No. Every image is read, compressed, and previewed entirely in your browser — nothing is sent to a server. It keeps working offline once the page has loaded.
JPEG, PNG and WebP. Each image comes back in the same format it went in. Other types like GIF, SVG or AVIF aren't supported yet and are skipped with a note.
For JPEG and WebP it sets the encoder quality. For PNG it controls color quantization — fewer colors means a smaller file. Lower the slider for more savings, raise it to stay closer to the original.
Never — if a re-encode would come out larger than the original (some already-optimized files do), the tool keeps the original bytes and shows it as already optimized.
When you download more than one image at once, they're bundled into a single .zip so everything comes down in one click. A single image downloads on its own.
No account, no watermark, and no hard limit. Since everything runs on your device, very large images are only bounded by your computer's memory.
