About Watermark PDF
Watermark PDF overlays text or an image across every page, or a chosen range, for branding, copyright notices, or status marking like "Draft" or "Confidential." Control opacity, rotation, position, and whether the mark sits above or beneath the existing content, so a subtle logo watermark and a bold diagonal "CONFIDENTIAL" stamp are both easy to produce from the same tool. Because the watermark becomes part of the page's content stream, it stays attached to the document through further edits, printing, or conversion.

When to use this
Use Watermark PDF when you need a fast, browser-only fix for a common PDF task without installing software or uploading files to a server.
Search intent
Before vs after
Before
You have a document that needs a quick change, but the workflow is blocked by file size, formatting, security, or organization issues.
After
The PDF becomes ready for sharing, submission, printing, or archival with the exact changes you needed without leaving the browser.
Common mistakes
- ! Skipping a quick preview before downloading the final file.
- ! Not checking the output on a real device before sending it to a colleague or portal.
- ! Using the wrong tool for the job because local PDF editing and conversion are not interchangeable.

Frequently asked questions
Can I use my company logo as a watermark?
Yes. Upload any PNG, JPG, or SVG image as your watermark and set its opacity and position.
Can the watermark be removed by the recipient?
Stamped watermarks are part of the content layer. While not impossible to remove with advanced tools, they are not easily editable.
Can I watermark only specific pages?
Yes. Use the page range selector to target specific pages — e.g., only the first page or pages 3-10.
What fonts are available for text watermarks?
Built-in PDF fonts (Helvetica, Times, Courier) plus any system fonts available in your browser are supported.
Does a tiled/repeating watermark pattern work?
Yes. Toggle the tile option to repeat the watermark in a grid pattern across each page.
