Protect PDF with Password

Add password protection to your PDF. Secure your documents with encryption.

Important Note:

PDF encryption requires specialized libraries that aren't available in basic browser environments. For production-grade password protection, we recommend using:

  • Adobe Acrobat (desktop software)
  • PDFtk (command-line tool)
  • Professional PDF editing software

This tool demonstrates the UI/UX but uses limited browser-based encryption.
