Mark a document as DRAFT or CONFIDENTIAL, or stamp your logo on it. Choose text or a picture, and set where it goes and how strong it looks.
How to use the Watermark PDF
- Upload your PDF.
- Type your text or choose a logo, then set the position and strength.
- Download your watermarked PDF.
What to expect
Text or logo
Use words such as DRAFT, or a JPG, PNG or WEBP logo. A logo's size is a percentage of the page width.
Your choice of position
Across the middle, repeated all over, or in any corner.
Control the strength
Set it from 5 to 100%, so your document stays easy to read.
Tips for a good watermark
- Strength of 20 to 35% is usually enough for text across the page.
- Use a logo with a transparent background so it doesn't look like a box.
- Repeat across is harder to crop out than a single mark in one corner.
Which position to use
| Position | Best for |
|---|---|
| Diagonal | DRAFT or COPY across the middle of each page |
| Repeat across | Material you especially don't want reused, as it's hard to crop out |
| A corner | A small logo on a brochure or report |
| Center | A logo behind a certificate or letter |
If the watermark makes pages hard to read
Lower the strength first, as 20 to 35% is enough for most text marks. The watermark is drawn over the page, so a dark color at high strength will cover your words. Go back to your original file each time, because a second watermark would be added on top of the first one.
