Client-Side PDF Password Protection & Encryption

Secure contracts, financial records, medical reports, or private documents before sharing them via email or public cloud storage. Add a strong password directly inside your browser.

Key Features:

  • Client-side encryption: Your secret password is never sent to our servers.
  • Live password strength and entropy indicator.
  • Compatible with Adobe Acrobat, Apple Preview, Google Chrome, and standard mobile viewers.

How to Use:

  1. Select or drag your PDF into the protection workspace.
  2. Enter your chosen password and confirm it with the live strength meter.
  3. Click "Encrypt & Protect PDF" to download your password-protected file.

Securing Important Documents Before Emailing

Email is unencrypted by default across many mail servers. Encrypting your PDF with a strong key ensures only intended recipients with the password can read the contents.

Frequently Asked Questions:
