PDF
Stamp a diagonal text watermark — like "Draft" or your company name — across every page of a PDF, with adjustable opacity so it doesn't obscure the content underneath. Add several PDFs to watermark them all in one batch.
How to use Add Watermark
- Upload the PDF you want to watermark.
- Type your watermark text and set the opacity.
- Tap Run to download the watermarked PDF.
FAQ
Can I use an image or logo as the watermark instead of text?
Not currently — this tool stamps text only; image-based watermarking may be added later.
Can the watermark be removed afterward?
It's drawn directly onto the page content, the same as printing text on paper, so it becomes a permanent part of that PDF — always keep your unwatermarked original as a backup.
