Image compressor for JPEG, PNG and WebP

Choose images, set quality and maximum width, then compress and save each result.

Free to use, with no sign up. Everything runs in your browser and nothing is uploaded.

Lower quality can save more space. PNG uses a color palette, so results vary by image.

Images keep their proportions and are never enlarged. Very large images may be limited further by your browser.

Frequently asked questions

Do my files leave my device?

No. Each file never leaves the device. Compression runs in your browser with nothing uploaded. The compression library is included locally.

Which image formats can I compress?

Choose JPEG, PNG or WebP files, including several at once. Results keep the original format when your browser supports it. Any format fallback is shown with the result.

Will every image get smaller?

No. Some images are already compressed. If a result is larger, the tool keeps your original file and reports zero space saved. Lower quality or a smaller width may help.

Does compression change my image?

A smaller width resizes the image, and lower quality may remove detail. Compressed JPEG results omit camera metadata. Keep your original if you need its full quality or metadata.
