Frequently Asked Questions
Where does the watermark appear on the page?
It's stamped diagonally across the center of every page, the classic "CONFIDENTIAL" or "DRAFT" look. Position and rotation aren't customizable yet — opacity and font size are.
Can I remove a watermark this tool added?
Not currently — the watermark is merged directly into the page content, the same way any PDF watermark works. Keep your original file if you might need an unwatermarked copy later.
Will it work on scanned or image-only PDFs?
Yes — the watermark is stamped on top of the page as a separate layer, so it works regardless of whether the underlying page is text or a scanned image.
Is my document kept on the server?
No. The file exists in server memory only for the moment it takes to process, then it's discarded. Nothing is retained or shared.
