How it works
- Choose a PDF file.
- Enter the text and set size, opacity, angle, colour and layout.
- Click “Add watermark” and save the PDF.
Notes and limitations
- The watermark is added as text on the page. Anyone who can edit the PDF can remove it again – it is not copy protection.
- Latin characters including accents are supported. Emoji or non-Latin scripts cannot be displayed with the standard font; you will get an error message instead.
- Optionally only on certain pages, e.g. “1-3”.
