How it works
- Add your PDF. This page opens with "Top center" selected - that is your header.
- Run the tool once for the header. For a footer too, run the result again with "Bottom center".
- By default the stamp is the page number. You can add a prefix to the number, or type your own text - your text replaces the number and the prefix.
Limits
- Stamps use a Latin font only: Hebrew, Arabic, CJK and emoji are not supported.
- Rotated pages must be rotated to 0 degrees first.
