Encrypt, decrypt, and secure PDF files

Add RFC 3161 trusted timestamps to PDF documents. Prove document existence at a specific point in time without certificates.

Password protect PDF files. Add encryption and set permissions.

Remove hidden data from PDFs. Clean metadata, scripts, and sensitive information.

Search and redact text across all pages of a PDF. Batch redact sensitive information like account numbers, names, and more.

Flatten PDF forms and annotations. Make content non-editable.

Strip metadata from PDF files. Remove author, dates, and document properties.

Modify PDF permissions. Control printing, copying, and editing access.

Add X.509 digital signatures to PDF documents. Sign PDFs with PFX, P12, or PEM certificates for legal validity.

Verify digital signatures in PDF documents. Check certificate validity, signer information, and document integrity.

Secure PDFs using asymmetric public-key certificate encryption, paired with a 3D gold wax-seal imprint and PKCS#7 signature.

Automatically detect phone numbers, emails, and IDs, overlay opaque masks, and physically erase underlying text streams.

Automatically locate signature fields in contracts, and inject interactive hovering guides and anchors for quick signing.

Lock PDF against printing, copying text, and modifying content with 256-bit AES encryption and master passwords.
