Start here

Text watermarks support basic English/Latin letters, numbers and punctuation. Watermarks appear over existing page content and are not security protection.
How to watermark a PDF online
Choose a PDF and enter a short word or phrase such as DRAFT, REVIEW COPY or CONFIDENTIAL. Pick which pages to mark, adjust opacity and the text angle, then save a new PDF. The original stays on your device.
What does a watermark do?
A text watermark signals that a document is a draft, a sample, or an internal copy. It can help readers distinguish versions, but it does not restrict copying, downloading or editing and should not be used as digital rights protection.
Best settings for legibility
Start with a short phrase and 15% to 28% opacity. Long labels may appear smaller to fit inside narrow pages. Always inspect exported pages to ensure the watermark does not obscure charts or signatures.
Frequently asked questions
Is a watermark the same as a password?
No. This is a visible text label, not encryption or permission control.
Can I watermark only page 2?
Yes. Enter 2 in the Pages field.
Can I use non-English letters?
The basic built-in PDF font supports Latin text. This tool will show an error for unsupported characters rather than producing a corrupted watermark.
