Secure PDF
Encrypt, decrypt, and secure PDF files
Use the secure PDF hub when the job involves permissions, privacy, access control, or hiding sensitive information before sharing a document.
Best for
- Encrypting PDFs or changing permissions before distribution.
- Removing metadata, sanitizing files, or checking digital signatures.
- Redacting or hiding sensitive information in client-side workflows.
How to choose
- Use Encrypt PDF when access to the file should require a password.
- Use Find and Redact when visible sensitive content should not be disclosed.
- Use Remove Metadata or Sanitize PDF when hidden document properties need cleanup.
Quality checks
- Open protected outputs and confirm the expected password or permission behavior.
- Try copying or searching redacted areas when the document is sensitive.
- Check document properties after metadata cleanup.
Privacy notes
- Security tools should only be used on documents you own or are authorized to modify.
- Encryption, redaction, and metadata cleanup solve different problems and may need to be combined.
