How to use it
Add a PDF and the pages appear as thumbnails with the watermark preview. Edit text, size, opacity and pages, then create the new PDF locally.
Recommended settings
For drafts, a diagonal center watermark at 20-30% opacity is usually readable without hiding the document. For subtle labels, use bottom right and a smaller size.
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.
