Add password protection to a PDF
Why protect a PDF with a password?
Password protection can reduce accidental access when a document is shared or stored. It is commonly used for statements, forms, reports and other documents that should not open without the password.
Create an encrypted copy
PDF85 creates a separate protected output so the original local PDF remains unchanged. Keep the password in a safe place because the protected file may be difficult or impossible to open without it.
Share the password separately
When sending a protected PDF, consider sharing the password through a different communication channel rather than placing the password in the same message as the attachment.
Password protection is not a complete security policy
Encryption is one control among many. Organizations handling regulated or highly sensitive data should follow their own storage, transmission and access-control requirements in addition to PDF password protection.
How to use Password Protect PDF
- Upload the PDF.
- Choose Protect PDF.
- Enter a password for the new encrypted copy.
- Download the protected PDF and store the password safely.
