Pro Tips
- Use 20-30% opacity for a subtle draft watermark that does not block reading.
- Rotate text watermarks 45° across the center for a classic diagonal "DRAFT" look.
- Use a transparent PNG logo for brand watermarks instead of text.
Frequently Asked Questions
Can I watermark only some pages?
▾
Yes. Set a page range (e.g., 1-5) in the options. Pages outside the range stay unmarked.
Can I watermark with an image?
▾
Yes. Upload a PNG or JPG. Transparent PNG logos look cleanest over the content.
Is the watermark permanent?
▾
It is written into each page. Use our Edit or Redact tool if you need to remove it later. The more resistant the watermark, the harder removal becomes.
Are my files private?
▾
Files are processed on EU servers (Germany) and deleted automatically after 30 minutes.
Is the watermark tool free?
▾
Yes. No registration, no subscription, and we do not add our own watermark.
Can I use special characters in text watermarks?
▾
Yes. Unicode is supported, including accented letters and most non-Latin scripts.
Does it work on mobile?
▾
Yes. Any modern browser on iOS and Android.
