About this tool
Add Watermark stamps your own text — 'CONFIDENTIAL', 'DRAFT', a company name, a copyright line — diagonally across every page (or just the pages you choose), with adjustable size, opacity and angle so it's visible without overwhelming the content underneath. It supports Arabic text as well as Latin text: Arabic is automatically rendered with a proper Arabic font fetched only when needed, so English watermarks stay fast and Arabic ones still render correctly rather than as boxes. Everything runs in your browser — the PDF is never uploaded.
Benefits & use cases
- Mark drafts so they aren't mistaken for a final version.
- Stamp 'CONFIDENTIAL' or a company name across shared documents.
- Add a copyright or ownership line to distributed PDFs.
- Works with Arabic text as well as English.
Frequently asked questions
Can I use Arabic text as a watermark?
Yes. Arabic text is detected automatically and rendered with a proper Arabic font, so it displays correctly rather than as empty boxes.
Can I watermark only some pages?
Yes, switch to 'Custom range' and enter the pages you want, like '1-3, 5'.
Can I add an image watermark instead of text?
This tool currently supports text watermarks only. For a logo or image stamp, use Sign PDF's signature placement as a workaround, or watch for a future update.
Is my document uploaded to add the watermark?
No. Watermarking happens entirely in your browser; the file is never sent to a server.
