What is a Ajouter un filigrane à un PDF?
A watermark marks a PDF as a draft, confidential, or attributed to a specific recipient before it's shared widely — common for reviewers circulating early contract drafts, photographers sharing proofs before a client pays for the final files, or a company stamping its logo across a document leaving its control.
How to use the Ajouter un filigrane à un PDF
- Add a PDF file, then choose text or an uploaded logo image
- Set its color/font (text) or position, and opacity
- Download the watermarked PDF
Example
Setting the text to "DRAFT — NOT FOR DISTRIBUTION" in red at 30% opacity, rotated 45°, stamps that phrase diagonally across every page — or switch to an uploaded logo image pinned to the bottom-right corner instead of centered text.
Why use Ajouter un filigrane à un PDF
Text or your own logo
Stamp a text watermark, or upload a PNG/JPG logo image to use instead — same position, opacity, and page controls either way.
Color, font, and rotation
Pick from 4 colors and 3 fonts for text, and set the angle a centered watermark sits at.
Center or a specific corner
The classic diagonal-across-the-page look, or pin it to a corner like a logo or stamp instead.
What can you create?
Mark a document as a draft
Stamp "DRAFT" or "NOT FOR DISTRIBUTION" across a contract or report before circulating it for review.
Brand a document with your logo
Pin a company logo to a page corner before sending a proposal or report outside your organization.
Mark proofs before a client pays
Watermark photo or design proofs so they're clearly identifiable but not the final deliverable.
Frequently asked questions
Is my PDF uploaded anywhere?
No — Ajouter un filigrane à un PDF runs entirely in your browser using JavaScript/WebAssembly. Your PDF is never sent to a server.
Is there a file size limit?
Free use covers files up to 100MB per file; signing up for Pro raises that to 500MB.
Can I remove a watermark I added with this tool later?
Not with this tool — the watermark is drawn directly into the page content, the same as the original text. Keep an unwatermarked copy of the source PDF if you'll need a clean version later.
Does the watermark show up when the PDF is printed, not just on screen?
Yes — it's rendered into the page itself, so it appears identically on screen, in print, and in any other PDF viewer.
Can I change the watermark's color, or is it always gray?
Yes — choose from 4 colors (gray, red, blue, black) plus opacity, and a font for text watermarks. Gray at partial opacity is just the default because it reads clearly without dominating the page underneath.
Can I use my own logo image instead of text?
Yes — switch the watermark type to Image and upload a PNG or JPG. It uses the same opacity, position, and page-selection controls as the text watermark.
Does the watermark have to be diagonal across the whole page?
No — choose a corner position (top-left, top-right, bottom-left, bottom-right) for a smaller, upright stamp instead of the classic centered diagonal. Rotation only applies to the centered position.
