Add password protection to your PDF files - processed locally in your browser
Allow after opening
Add a password to a PDF so it can't be opened without it. The file is encrypted with the PDF standard security handler (128-bit RC4) â the same mechanism Adobe Acrobat has used for decades.
Use at least 8 characters. A mix of letters, numbers, and symbols is stronger than a long single word. There is no password recovery: if you lose it, the file cannot be opened, so keep a copy of the password somewhere safe.
The whole document is encrypted â text, images, and metadata all require the password. By default the file can still be printed after opening, but not modified or copied from.
Files are processed entirely in your browser â nothing is uploaded to a server.
