How To Add A Watermark To A PDF
Watermarks signal intent. DRAFT tells the reader this isn't final. CONFIDENTIAL tells them not to forward it. SAMPLE tells them not to use it in production. Without the watermark, the same information might end up in the wrong hands.
Watermark PDF adds a text watermark to every page in seconds. Color, opacity, size, and six position presets - all configurable, all in your browser.
Position Options
Diagonal is the classic watermark look - the text runs corner-to-corner across each page at a 45-degree angle. This is the right pick for DRAFT, CONFIDENTIAL, or any text you want impossible to ignore.
Center, top, and bottom positions are more subtle and work better for smaller marks like a company name or document ID. Each of those has left, center, and right variants - six total positions.
Style The Mark
Color, opacity, and font size are all dialable. A high-opacity red diagonal DRAFT communicates urgency. A low-opacity gray center watermark with your company name communicates ownership without dominating the page.
Pick what fits the document. The same tool works for a contract draft and a marketing one-pager.
How To Watermark
Open Watermark PDF. Drop in your PDF. Type the watermark text - up to 80 characters reads well. Adjust position and style. Click Watermark. The PDF rebuilds with the mark applied to every page, in your browser.
Can The Watermark Be Removed
The watermark is drawn into the page content stream - it's part of the page, not a separate annotation. Removing it cleanly requires PDF editing software, not casual reading or viewer-level controls. For most purposes that's enough.
For genuinely security-critical marks, pair this with Flatten PDF and Protect PDF to lock down editing and viewing.
Mark documents the right way with Watermark PDF. Free, in your browser, every page covered.
