Add a Password to PDF

Ready

Protect a PDF with an opening password. Upload the document, confirm your password and download the protected PDF, then check that opening it requires the password.

All tools are free to use. File size and processing limits may vary by tool.

How to use Protect PDF

Select the file, fill in both password fields; the process stops if they differ. The PDF opens asking for the password. Write the password down somewhere: a locked PDF has no recovery path.

How are files processed?

Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.

Practical guide

Protect PDF: Add Password Protection to Files

Emailing salary slips, employment contracts or client proposals without protection can expose private details if a message is forwarded by mistake. The Protect PDF tool lets you add a user password that must be entered before the document opens. Files are uploaded to the server for processing, each file must be under 20 MB, and the download link expires after 60 minutes. Choose a password with at least 12 characters including uppercase, lowercase, numbers and symbols, share it through a separate channel, and store it safely.
