Will sanitizing PDF change the document content?

No. Sanitization only removes metadata and hidden additional content. The visible page content of the document remains unchanged.

Can I sanitize only specific items?

Yes. You can selectively clean metadata, JavaScript, embedded files, hyperlinks, or comments in any combination.

Can metadata be recovered after sanitization?

No. Sanitization is permanent. Deleted metadata cannot be recovered. It's recommended to keep a backup of the original document.

Why should I sanitize PDFs?

PDFs may contain creator information, edit history, hidden annotations and other sensitive data. Sanitization removes this information before sharing, protecting your privacy.

Will sanitization reduce file size?

It may reduce slightly, especially when removing embedded files or large numbers of annotations. But the main purpose is security rather than compression.
