PDF Permissions
Restrictions are honored by compatible readers and are not equivalent to cryptographic secrecy.
PDF permissions use standard permission profiles. Compatible PDF readers decide how those restrictions are enforced.
Sanitize Document
Inspect privacy-sensitive document structures first, then remove only supported categories you select.

Batch Security
Choose the batch PDFs here. The Current PDF used by the single-file tabs is not included. Files are processed sequentially and successful outputs are packaged into one ZIP.
No. Adding a visible signature does not independently authenticate a person. If a recipient requires certificate validation or an approval workflow, check their requirements before using a visual signature.
What happens to searchable text on a redacted page?
Affected pages are rebuilt as raster images, so their original text layer is removed. Unmarked information on those pages remains visible in the page image; check all visible details carefully.
Do PDF permissions guarantee that nobody can copy content?
No. Viewer support for permission restrictions varies. Use encryption for controlled opening, review sanitized output, and use secure redaction when sensitive page content must be removed.
Privacy: PDF bytes, signatures, passwords and redaction data stay on this device.
Apply secure redaction?
