Frequently asked questions
Why sanitize a PDF before sharing?
A PDF can carry scripts, attachments or hidden data such as the author's name. Sanitizing removes these invisible extras before you send it.
Does sanitizing change how pages look?
No, text and images stay the same. If you choose to remove comments, notes and highlights added to the file will disappear.
Sanitize PDF or Remove metadata — what's the difference?
Remove metadata strips author and app information. Sanitize also removes scripts and attachments, and can remove links and comments.
How do I remove JavaScript from a PDF?
Keep the JavaScript option switched on, as it is by default, and press sanitize. Scripts are stripped from the clean copy you download.
Is my file stored after sanitizing?
No. It's uploaded encrypted, processed and deleted right away; no copy is kept.
