Control access, remove restrictions when you have permission, redact sensitive details and recover damaged PDF files.
Security and repair tools protect the parts of a PDF workflow that can cause the most friction: passwords, permissions, sensitive content and files that will not open cleanly.
| Tool | Best when | Use next |
|---|---|---|
| Protect PDF | Protect PDF files by adding a password. | Unlock PDF, eSign PDF |
| Unlock PDF | Remove password protection from your PDF. | Protect PDF, Repair PDF |
| Redact PDF | Permanently black out sensitive PDF text and areas | Protect PDF, Unlock PDF |
| Repair PDF | Repair a damaged PDF and recover data from a corrupt file. | Compress PDF, Merge PDF |
Use Protect PDF when a completed document needs a password. Use Unlock PDF only when you own the file or have permission to remove restrictions. The distinctions are mapped in password protect vs encrypt vs restrict editing.
Use Redact PDF for personal data, financial details, signatures, account numbers and internal notes that should not remain recoverable in the shared file. For financial documents, follow redact Social Security numbers and bank details.
Use Repair PDF before merge, compression, conversion or signing if the document fails to open, displays errors or appears damaged.
Use Unlock PDF only on files you own or have permission to modify.
Protect the final version after editing, redacting, signing or compressing so recipients get the completed file.
