Details
Answers before you start.
The important questions, plus the nearby routes users usually need next.
Yes. Switch the watermark type to Image and upload a PNG or JPG. PNG transparency is preserved, so logos sit cleanly over the page.
Yes. The watermark is drawn over the page content, so it stays visible on scans and image-heavy PDFs — not hidden behind them.
The watermark becomes part of the page content. Like any visual watermark, a determined user with PDF tools could remove it — for tamper-proofing, combine it with PDF protection.
No. Watermarking runs entirely in your browser — your PDF and your logo never leave your device.
