Add a Watermark to a PDF
No account. No upload. Just the tool.
You’re sending a draft contract and want every page stamped DRAFT so nobody mistakes it for the final. Or your company sends out proposals and wants its name across every page in a faint diagonal. Signegy adds a text watermark to every page of a PDF, in your browser. No upload, no signup.
How to Add a Watermark
- Drop your PDF onto the tool above.
- Type your watermark text. Defaults to CONFIDENTIAL, but anything works — DRAFT, SAMPLE, your company name, the date.
- Pick a position: center (one stamp in the middle of each page), tile (a 3×4 grid of stamps), or corner (small stamp in the bottom-right).
- Set the opacity (5%-60%), angle (-90° to +90°), and font size.
- Click “Watermark N pages” — the result downloads with watermarks on every page.
A subtle watermark (15-25% opacity at -30°) is usually enough to make the document feel marked without overwhelming the actual content. A heavier stamp (40-60% opacity, larger size) makes it impossible to miss.
Common Use Cases
Drafts. A contract or proposal that’s still in revision. Stamping DRAFT prevents an early version being mistaken for the final.
Confidentiality marking. CONFIDENTIAL or PROPRIETARY signals to the recipient that the document isn’t for redistribution.
Sample copies. Sales materials, course excerpts, white papers handed out as previews — stamping SAMPLE keeps a sample copy from being mistaken for the full deliverable.
Tracing leaks. Stamp each recipient’s name on their copy of a PDF. If the file shows up where it shouldn’t, the watermark identifies the source.
Brand presence. Your company name across every page of a presentation or report.
Honest Limits
- Text only. Image / logo watermarks aren’t in v1.
- Same watermark on every page. No alternating styles or first-page exclusion.
- Single watermark per page. If you need multiple stamps with different content, run the file through twice.
- Baked in. Once applied, the watermark is part of the page content. There’s no clean removal — keep an unwatermarked master.
Pair With Other Tools
- Compress PDF before sending if the file is large.
- Add page numbers at the same time you add the watermark to keep both styles consistent.
- Edit metadata to set the title and author alongside the visible watermark.

Frequently Asked Questions
What watermark text should I use?
Common ones: DRAFT (work in progress, not final), CONFIDENTIAL (don't redistribute), SAMPLE (illustrative copy, not the real document), your company name (claim of authorship), or the recipient's name (so the file can be traced if it leaks).
Can I use an image watermark?
Not yet. v1 supports text only. If you need a logo watermark, an interim workflow is to add the logo as an image overlay using a PDF editor, or convert the logo to a stylized text string for now.
Can I remove a watermark from a PDF?
Once the watermark is baked into the PDF (which is what this tool does), removing it cleanly is hard. The text becomes part of the page's content stream. The honest answer: design the watermark to look like a watermark, and don't apply one to a master copy you might want clean later.
Will the watermark print?
Yes. The watermark is drawn into the page content, so it appears in print, in screenshots, in text extraction, and in every viewer.
Does this work on encrypted PDFs?
No. Encrypted PDFs need to be unlocked first.
