About This Tool
What This Tool Does
Stamps a text watermark onto every page of your PDF. Useful for marking documents as DRAFT, CONFIDENTIAL, SAMPLE, or with your company name to discourage casual redistribution.
Customization
- Text — any short string
- Position — center, corners, or repeated across the page
- Font size, color, opacity — make it subtle or bold
- Rotation — angled diagonals look more like classic watermarks
Tips
- 30-40% opacity is a sweet spot — visible but not overwhelming
- Diagonal 45° rotation at the page center is the most traditional watermark style
- Repeat tile mode makes the watermark much harder to remove with cropping
Frequently Asked Questions
Can the watermark be removed by someone with Acrobat?
Text watermarks added as drawn text are part of the page's content stream. They can be removed by someone with Acrobat or qpdf who has edit permissions. For stronger protection, combine watermarking with password protection on the owner password.
Why does diagonal text seem off-center?
Rotated text is positioned by its baseline-left point, not its visual center. The tool compensates by calculating the offset based on text width and rotation angle. Small variations may still appear depending on font and angle.
Will the watermark appear on every page automatically?
Yes u2014 the tool iterates through every page and stamps the watermark on each one. There's no per-page exclusion in this simple version. To watermark only some pages, split the PDF first, watermark the selected pages, then merge back.
