Secure PDF
Encrypt, decrypt, and secure PDF files
Encrypt PDF Online — Add PDF Password Protection
Encrypt a PDF online with password protection and review the protected output before sharing sensitive documents.
Sanitize PDF Metadata and Hidden Data
Perform best-effort structural PDF cleanup for selected metadata, actions, attachments, links, forms and annotations. Review the output before sharing.
Find and Redact
Find sensitive text in a PDF and review matches. Secure redaction export is temporarily disabled because visual masking alone does not remove recoverable PDF content.
Decrypt PDF — Remove Password Protection You Are Authorized to Remove
Remove password protection from PDFs when you have the required password and authorization. Create an accessible copy for legitimate document workflows.
Flatten PDF
Flatten PDF forms and annotations. Make content non-editable.
Remove Metadata
Clear selected standard PDF document-info properties such as title, author, subject, keywords, creator and producer. Review the stated metadata limits before sharing.
Change Permissions
Modify PDF permissions. Control printing, copying, and editing access.
Digital Signature
Add X.509 digital signatures to PDF documents. Sign PDFs with PFX, P12, or PEM certificates for legal validity.
Validate PDF Digital Signature Online
Inspect digital signatures in a PDF, review signer and certificate details, and understand whether the signature structure validates without overstating identity proof.
