Frequently asked questions

What's the best quality for the web?
Around 75–85 for JPG/WEBP gives 60–80% size reduction with little visible loss for most photos.
Will compression damage the original?
No — the original file on disk is untouched. The tool generates a new compressed version you can save separately.
