Beginner Guide to Protect PDF

Protect PDF files with a password before sending contracts, reports, invoices, or sensitive internal documents.

What this tool is best for

• Sending confidential PDFs by email
• Restricting access to internal reports
• Sharing documents that should not open freely

Step-by-step workflow

1. Upload your PDF.
2. Enter the password required to open the file.
3. Optionally set an owner password.
4. Download the protected PDF.

Best ways to use it

• Use a strong password rather than a short simple code.
• Share the password over a separate channel when possible.
• Test the protected file before you send it onward.

Security notes

• Password protection helps control who can open the file.
• The PDF content is not changed, only the file access rules.
• You should still handle the file carefully if it contains sensitive data.
