Using PDF watermarks well
Text or image?
Use text for status labels such as DRAFT, COPY or CONFIDENTIAL. Use an image for a logo or signature-style mark. The built-in PDF fonts support basic Latin characters only, so for other scripts create an image of the text and use it as an image watermark.
Keeping the document readable
- Lower the opacity so the page text stays legible; the default is 35%.
- A diagonal watermark of 45° is common because it crosses the page without covering one block of text.
- Use an edge position with a small size for letterheads or logos, and the center position for status labels.
- Use the page selection to leave a cover page or signature page unmarked.
What a watermark can and cannot do
This tool adds a visible mark to a copy of your PDF. It does not encrypt the file, prevent copying, or guarantee that the mark cannot be removed. Keep your original PDF and do not rely on a visible watermark as the only protection for sensitive documents.
Troubleshooting
- The PDF will not open: it may be damaged or password-protected. Remove the password in the program that created it, then try again.
- Letters are missing from the text: unsupported characters are skipped. Use an image watermark instead.
- Tiling shows only one mark: the settings would create too many copies. Increase the size or spacing.
- The mark looks different in another viewer: open the downloaded PDF in your usual viewer and adjust the size, opacity or position.

Frequently asked questions
How do I add a watermark to a PDF?
Choose a PDF, create a text or image watermark, set its position, opacity and rotation, choose the pages, then apply and download.
Can I use my logo?
Yes. Select a PNG or JPG that you have the right to use. A PNG with a transparent background usually looks best.
Can I repeat the watermark across the page?
Yes. Turn on tiling. If the settings would create too many copies, a single mark is used, so increase the size or spacing.
Does a watermark protect my document?
No. It is only a visible mark and can be removed. Do not rely on it as the only protection for sensitive documents.
Why are some letters missing?
The built-in PDF fonts skip characters outside basic Latin. Use an image of the text instead.
Is my PDF uploaded?
No. The watermark is added in your browser, and the file is not sent to our server for this tool.
