Watermark
Stamp text or an image on every page or a range. Set opacity, rotation from −90° to 90°, and a centered or tiled layout.
What Watermark does
Watermark stamps text, such as CONFIDENTIAL or DRAFT, or an image such as your logo onto the pages of a PDF. Place it once in the center of each page or tile it across the page.
How to add a watermark to a PDF
- Drop a PDF on the box above.
- Choose Text or Image / logo. Set the text, size and color, or choose an image and its size.
- Adjust Opacity, Rotation, Layout and Pages, then select Add watermark.
Settings
| Text | Font size 12 to 160 pt, optional bold, color from the swatches. Default: CONFIDENTIAL, 64 pt, bold. |
|---|---|
| Image / logo | PNG, JPG or WebP. Size from 5% to 100% of the page width. PNG with transparency works best. |
| Opacity | 5% to 100%. Default 25%. |
| Rotation | -90° to 90° in 5° steps. Default 45°. |
| Layout | Centered (once per page) or Tiled (repeated across the page). |
| Pages | All pages, or a custom range. |
Limits
- Text in Latin letters is drawn as real text in Helvetica. Other scripts, such as Cyrillic, Chinese or Arabic, are drawn as an image using your device's fonts.
- A watermark discourages copying but doesn't prevent it: anyone with a PDF editor can cover or remove it.
Where your file goes
Watermarking runs in this browser tab. Your PDF and your logo aren't uploaded.
If you're signed in, the result panel also offers Save to My documents. Only that button uploads the file, to your account's storage.
Questions
Can I use my logo as a watermark?
Yes. Choose Image / logo and pick a PNG, JPG or WebP file. A PNG with a transparent background looks best, especially at low opacity.
Can someone remove the watermark?
It's drawn into the page content, not added as a comment a reader can hide. Someone with a PDF editor can still cover or remove it. To discourage edits, run Protect PDF afterwards and leave Allow editing off.
Can I watermark only some pages?
Yes. Under Pages, choose Custom and type the pages or ranges, for example 1, 3-5.
How do I make the watermark lighter?
Lower Opacity. The default is 25%; 10% to 15% keeps text under it easy to read.
