PDF Tools
Secure your PDF files by adding password encryption. Restrict viewing, editing, copying, or printing permissions.
Follow these simple steps to get instant, accurate results directly in your browser:
Choose the unprotected PDF document you wish to encrypt.
Type and confirm your chosen password.
Click 'Encrypt PDF' to download your secure, password-locked file.
The Password Protect PDF tool secures sensitive PDF documents with standard cryptographic encryption, requiring a password before contents can be opened or viewed.
The utility applies standard PDF security specifications (including 128-bit and 256-bit AES encryption), encrypting all content streams, metadata, and cross-reference dictionaries with your chosen master passphrase.
Because encryption occurs entirely in your browser using local cryptographic routines, your password and your unencrypted document are never transmitted across the network.
Enforces industry-standard cryptographic protection recognized by all modern PDF readers.
Passphrases and document bytes never leave your device's memory.
Secured files unlock smoothly in Adobe Acrobat, Apple Preview, and modern web browsers.
Encrypts documents in seconds using local device CPU.
Protect employee payroll summaries, medical evaluations, and background checks.
Safely distribute tax returns, banking audits, and investor reports via email.
