Watermark

Mark every page of a PDF

Put a word such as CONFIDENTIAL or DRAFT, or a logo, on every page of a PDF. You set where it sits and how strong it is, and see it on the page before you run it. The file is never uploaded.

How to add a watermark to a PDF

1. Choose a PDF

   Pick the file or drop it on the page.

2. Set the watermark

   Type the text, or pick an image file (PNG or JPEG). Pick the position, run it corner to corner if you like, and set its size and strength. The preview follows every change.

3. Add it

   Press Add watermark and download the marked PDF. The original stays as it was.

The same mark on every page

• The mark is drawn onto the existing pages, so text, links and form fields underneath keep working.
• Text is set in Helvetica and takes Latin letters, including most Western European accents. Letters such as Ł or Ś, and other scripts, can’t be drawn yet, and the page tells you before you run it.
• An image is used as it is; it is not sent anywhere and not kept after you leave the page.
• A password-protected PDF stays protected with the same password.

Questions

Is my PDF uploaded when I add a watermark?

No. The watermark is drawn by code in your browser, on your device. Neither the PDF nor the logo is sent anywhere.

Can I use a logo as a watermark?

Yes. Choose a PNG or JPEG image; a PNG with a transparent background works best.

Can I change the position and transparency?

Yes. Choose one of seven positions or corner to corner, and set how strong the mark is.

Can a watermark be removed again?

A watermark is ordinary page content, so someone with a PDF editor can remove it. It marks a document; it does not lock it.
