What does this PDF tool do?
Click where the new words belong, type, then adjust the font, size, color or alignment. You can move or duplicate the text box before exporting.
Document processing happens in your browser. SunPDF does not upload your PDF to a server for editing. Closing or refreshing the tab ends the current session.
When to use this tool
Add text for a missing note, date, or answer without treating the new box as a replacement for content underneath it.
How to check the result
Check contrast, alignment, and margins at reading or printing size, then reopen the file to confirm the position.
