How to Add a Watermark to a PDF — Free Online Tool

Adding a watermark to a PDF is the standard way to mark a document as confidential, a draft, or the property of your organisation. PDF me lets you stamp any text or upload a logo image to appear on every page — completely free in your browser.

What is the PDF Watermark tool?

The Watermark tool in PDF me places a repeating text label or image overlay on every page of your PDF. You can customise the text content, font size, opacity, color, rotation angle, and position. Logo watermarks support PNG or JPEG images and can be sized and placed to suit your layout.

Why add a watermark with PDF me?

• Protect confidential documents: Mark sensitive files as CONFIDENTIAL or INTERNAL to reduce misuse risk.
• Brand your documents: Stamp your company name or logo on every page to reinforce ownership.
• Mark draft versions: Add a DRAFT watermark to documents still under review so recipients know the status.
