What formats are supported (JPG, PNG, WebP, HEIC)?

How does this image compressor work?

It re-encodes images with optimized settings and optional downscaling to reduce file size.

Will compression reduce visible quality?

At moderate quality (60–80) most images remain visually similar; use higher quality for critical shots.

Can I compress multiple images at once?

Yes, upload multiple files and download them individually or as a ZIP.

Is there a limit on file size?

Individual uploads are limited to 15 MB to keep processing fast.
