Frequently Asked Questions

Is it safe to compress private family photos here?

Yes. Compression runs in your browser with locally served JavaScript libraries. The page does not upload image bytes to an external processing service.

How does the quality comparison slider work?

After you add files, the page creates a quick preview for the selected image. The slider shows the original on one side and the compressed result on the other.

Can I convert images to modern WebP format?

Yes. Under options, switch the output format preset to WEBP. This often yields substantial extra compression savings while keeping transparent layers intact.
