Add a Watermark to PDF — Make the Document's Purpose Clear

Mistaking a draft for the final version, or internal material leaking outside, usually happens because the document has no marking. Laying text like "For review" or "Confidential" on every page greatly reduces such misunderstandings.

The watermark text is drawn on screen first and then laid onto the document, so any characters and emoji display without breaking. Adjust opacity, angle, size, and color to find a line that doesn't hurt readability.

Both the traditional large diagonal mark across the center and a tiled repeat across the whole page are supported. Tiling makes it harder to crop out with a screenshot.

Limits of this tool

  • A watermark is a graphic drawn over the page. It can be removed with professional editing tools, so it's not a legal protection measure.
  • Adding an image as a watermark (logo insertion) isn't available yet.

How to use

  1. 1

    Select a PDF

    Upload the document to watermark.

  2. 2

    Set text and appearance

    Enter the text to display and adjust opacity, angle, size, color, and layout. A preview shows the result.

  3. 3

    Apply and save

    Download a new PDF with the watermark applied to every page.

Key features

  • Any script and emoji

    Because the text is rendered as an image and laid on, any character displays as-is without font limits.

  • Opacity control

    Go light so it doesn't hinder reading, or dark so it's clearly noticeable.

  • Diagonal or tiled

    Choose between one large mark in the center or a repeat across the whole page.

  • Drawn above content

    The watermark is drawn above the page content so it isn't hidden by the body.

When to use it

  • Marking drafts

    Put a "Draft" mark on documents under review so they aren't confused with the final.

  • Indicating the audience

    Clearly leave the document's purpose, like "Internal" or "For client."

  • Protecting sample material

    Leave a mark on material shared as a preview to discourage unauthorized use.

How are your files handled?

Watermark compositing happens in your browser. The text you enter never leaves your device.

Selected files open only in your browser's memory, and results are handed straight to your device when you save. Close the tab and any remaining data is gone with it. See the Privacy Policy and File Retention Policy for details.

Add Watermark FAQ

Can I remove the watermark later?
Not with this tool. Be sure to keep the original separately.
Can I add it to specific pages only?
For now it applies to all pages at once. If you need only some, you can split, apply, and then merge again.
The body is hard to read.
Lower the opacity (e.g., 15%) and reduce the font size. For tiling, widening the spacing feels less crowded.
Is a watermark a copy-protection feature?
No. It's only a mark that signals the document's purpose and discourages leaks — it provides no technical access control.
