Add Text Watermark to PDF — Protect Every Page

Stamp a diagonal, semi-transparent text watermark across every page of a PDF — words like DRAFT, CONFIDENTIAL, SAMPLE, or your company name. Opacity is adjustable so the watermark is visible without hiding the underlying content.

Why watermark a PDF?

Watermarks make it obvious when a document is a draft, a preview, or not the final signed version. They also discourage casual copying by putting your name across every page.

Adjust opacity to taste

Opacity ranges from very light (0.05) to bold (0.6). Lighter is more elegant; heavier makes the watermark impossible to miss. Test on one page and tweak if needed.

Frequently Asked Questions

Can I use my logo instead of text?

This tool uses text only. For logo watermarks, add the logo to the source document in Word/Illustrator before exporting to PDF.

Can the watermark be removed by the recipient?

The watermark is drawn as a permanent content stream — casual users cannot remove it. A determined attacker with Acrobat Pro can, so watermarks are a deterrent, not encryption.

What about watermarking only some pages?

Split those pages out, watermark them, merge back.
