PDF Password Generator
Generate a strong, random password to use when password-protecting a PDF, right in your browser. Adjust length and character types, see a strength indicator, and copy the result with one click. Nothing is sent to a server.
Strong passwords by default
Passwords are generated using your browser's cryptographically secure random number generator, mixing letters, numbers, and symbols.
Customizable
Adjust the length from 8 to 32 characters and toggle uppercase letters, numbers, and symbols on or off to match a specific PDF tool's requirements.
Use it with your PDF editor
This tool generates the password only - apply it in Adobe Acrobat, Preview, or another PDF editor's "Set Password" or "Protect" feature, since browsers cannot apply PDF encryption directly.
Common Mistakes to Avoid
Expecting this tool to encrypt the PDF itself
Solution:
This tool only creates the password text. You still need a PDF editor to apply password protection to the file.
Choosing a very short password for sensitive documents
Solution:
Use at least 12-16 characters with symbols enabled for documents that need real protection.
