How to use it
Add images and check the before-and-after preview. The editor re-saves each selected file in the chosen format without sending it to a server.
Recommended settings
Black and white works well for documents, listings, print and a consistent product-card style. Use JPG 86-92% for photos, or PNG/WEBP when transparency matters.
Privacy
Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.
Limits
Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
