About Watermark PDF
Place a diagonal text watermark at the center of every visible page, including rotated or cropped pages. A standard PDF font is used, so character coverage is limited.
How to use it
- Select an unencrypted PDF.
- Enter the watermark text.
- Apply it and check the center of each downloaded page.
Frequently asked questions
Is a watermark a security measure?
No. A visible watermark can be edited or removed; it does not protect the document.
Does this support every writing system?
No. The built-in standard font has limited character coverage; some characters cannot be encoded.
