Add a text watermark — DRAFT, CONFIDENTIAL, your business name — across every page of a PDF. Adjustable size, opacity and angle. Runs in your browser. Free.
🔒 Watermarking happens in your browser — your PDF is never uploaded.
A watermark communicates status and ownership at a glance without obscuring the content. "DRAFT" stops an unfinished version being mistaken for final; "CONFIDENTIAL" sets expectations before anyone reads a line; a business name deters casual copying of quotes, proposals and reports. A light, diagonal watermark is the sweet spot — visible enough to register, faint enough to read straight through. Keep opacity low so the underlying text stays perfectly legible.
Finish the document with Page Numbers, assemble it with the PDF Merger, or brand your business paperwork with the Quote and Invoice generators.
Different documents call for different marks. A DRAFT watermark on a proposal or contract prevents an in-progress version being mistaken for the signed-off one — a genuinely costly mix-up in business. CONFIDENTIAL or INTERNAL ONLY sets the reader's expectations before they've read a word, and is a simple, sensible habit for anything containing pricing, personal data, or strategy. A business name across quotes, portfolios and reports quietly discourages casual copying and reinforces your brand every time the document is shared.
The settings matter as much as the text. Keep opacity low — "Very light" or "Light" — so the watermark registers without fighting the content underneath; a watermark so dark it obscures the text defeats the document. The diagonal angle is the traditional choice because it spans the page and is hard to crop out, while horizontal suits a subtle footer-style mark. Size to roughly the width of your page for a full-bleed effect, or smaller for a discreet corner stamp. Because the mark is merged into every page, it travels with the file wherever it's forwarded or printed.
Is my file uploaded?
No — the watermark is drawn onto every page inside your browser, and nothing is sent to a server.
Can the watermark be removed by others?
It's merged into the page content, so it can't be toggled off like a layer. It's a strong visual deterrent, though determined editing tools can remove any watermark — it's not encryption.
Will it make my text unreadable?
Not at light opacity — pick "Very light" or "Light" and the content reads clearly straight through the mark.
Can I use an image or logo?
This tool applies text watermarks. For a logo, add it as text of your business name, or place the logo on pages before exporting to PDF.
Does every page get the watermark?
Yes — it's applied uniformly across all pages of the document.
