Frequently asked questions

Are online PDF tools safe for sensitive documents?

Upload-based tools copy your file to their server. Browser-local tools never send the file anywhere — there is nothing to breach or retain.

How do I remove sensitive data before sharing a PDF?

Use the redact tool to permanently black out text, then encrypt with a password for transit. Both run locally.

How can I check a PDF for hidden data?

Run the privacy scanner — it flags metadata, hidden layers, and embedded info you may not know the file carries.
