How to use it

Add a PDF, choose JPEG quality and page scale, then process. The file stays on your device while pages are rendered locally.

Recommended settings

For scans and slides start with 65-75% JPEG quality and 100-110% scale. Increase quality if small text becomes soft.

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.
