Sending sensitive documents by email always carries a risk. Password protecting your PDF adds an extra layer of security — the recipient needs the password to open the file, even if the email is intercepted or forwarded unintentionally.

When Should You Password Protect a PDF?

How to Add Password Protection for Free

  1. Go to the EggyPDF Protect PDF tool — EggyPDF encrypts your file instantly
  2. Upload your PDF file
  3. Enter the password you want to set
  4. Download your password-protected PDF

Share the password separately from the file — send it by SMS or phone call rather than in the same email as the attachment.

Choosing a Strong Password

How is This Different from Encryption?

Password protection restricts who can open the file. Encryption scrambles the content so it cannot be read even if the file is accessed. EggyPDF's tool applies both — the PDF is encrypted using AES-256 standard, which is the same encryption level used by banks.
