Compress images without uploading
Reduce file size for the web, email, or storage with a quality slider and a live before/after preview that shows exactly how many bytes you save. The compression happens on your device, so even large images never get uploaded.

Frequently asked
- Will compressing reduce image quality?
- You control the trade-off with a quality slider and see the result live. WebP and AVIF usually give the smallest files at a given quality; PNG stays lossless.
- Can I compress many images at once?
- Yes. Drop two or more images to get a batch view, then compress them all and download the results as a zip — still entirely in your browser.
- Is there a file size or count limit?
- Images up to 50 MB and 4096×4096 px are supported. There is no cap on how many free operations you can run.
