PDFs can carry far more than pages: scripts that run on open, hidden attachments, comment threads and author details. Sanitize PDF removes these extras so you can share a clean document – or neutralise a file you received from an unknown sender.
How to sanitize a PDF
- Add the PDFs to clean.
- Choose what to remove.
- Sanitize and download. A report lists everything removed.
Good to know
- Sanitizing removes active content and hidden data. It does not remove visible text – use Redact PDF for that.
- Removing JavaScript may break interactive calculations in complex forms.
Frequently asked questions
Can a PDF contain a virus?
PDFs can contain scripts and attachments that have been abused by attackers. Removing them reduces risk, though keeping your PDF reader updated matters most.
What is PDF metadata?
Information such as title, author, software and dates stored inside the file.
Does sanitizing change how pages look?
No, unless you choose to remove annotations, which removes comments and stamps from view.
