About This Tool
A PDF containing personal, financial or business information deserves more than a filename nobody can guess. Encrypt PDF adds password protection and security controls before you share or archive the document.
Use a strong, unique password and share it through a separate channel when possible. Encryption can protect the file itself, but it cannot protect a password that is sent alongside the attachment in the same message.
How to Use
Add the PDF
Choose the document you want to protect.
Set a strong password
Use a unique password that is not reused for another account or service.
Choose security options
Select the appropriate encryption and permission settings for your use case.
Save and share safely
Download the protected PDF and send the password separately from the file.
Use Cases
Sensitive paperwork
Add an extra protection layer to documents containing personal or financial information.
Secure email delivery
Protect an attachment and communicate its password through another channel.
Archive protection
Store confidential PDFs behind password-based access controls.
Frequently Asked Questions
What if I forget the PDF password?+
Keep a secure record of passwords you create. Do not rely on a recovery mechanism that the document format may not provide.
Does encryption hide the file name?+
No. Encryption protects the document contents, not the surrounding filename, folder or message metadata.
Should I send the password with the PDF?+
Avoid sending both through the same channel when the document is sensitive. Use a separate trusted channel.
