About PDF Watermark
Confileo's PDF Watermark tool stamps a text or image watermark across every page of a PDF. Everything runs in your browser, free and without signup, and your files are deleted automatically after processing.
Watermarks protect documents from misuse, mark drafts and confidential copies, and brand your files with a logo — essential for designers, agencies and anyone sharing work before final approval.
Confileo's PDF Watermark tool stamps text (like “Confidential” or “Draft”) or your logo across every page, with full control over position and opacity so the mark protects the page without hiding the content.

PDF Watermark — Frequently asked questions
Can I control the watermark transparency?
Yes. Adjust the position and opacity so the watermark protects the page without hiding the content.
Does it watermark every page?
The watermark is applied consistently across all pages of the document.
Can I add my company logo as a watermark?
Yes. Upload your logo image and place it as a watermark across every page to brand and protect your documents.
How do I stamp 'Confidential' or 'Draft' on every PDF page?
Add the text you want (such as “Confidential” or “Draft”) and it is applied to every page automatically.
Does the watermark affect readability?
Not if you set the opacity. A light watermark protects the document without hiding the text behind it.
Why add a watermark to a PDF?
To protect copyright, deter misuse of documents, and clearly mark drafts or confidential copies.
Can I use either text or an image as the watermark?
Yes. Add a text watermark like CONFIDENTIAL or DRAFT, or upload an image or logo.
Can I choose where the watermark appears and its angle?
Yes. You can set the position and rotation so it sits where you want on every page.
Can the watermark be removed later?
The watermark is merged into the pages, so keep an unwatermarked copy of the original if you may need a clean version.

Yes. Every Confileo tool is free to use with no daily caps, no watermark on your output and no credit card required.
