Our Mission

At PDF2Locker, our mission is simple yet powerful: to provide everyone with free, secure, and private PDF password protection without compromising on privacy or security.

In an era where data breaches and privacy concerns are at an all-time high, we believe that securing your documents shouldn't require uploading them to unknown servers or trusting third parties with your sensitive information. That's why we built PDF2Locker with a client-side first approach — your files never leave your device.

Why We Created PDF2Locker

The inspiration for PDF2Locker came from a common problem: most online PDF protection tools require you to upload your files to their servers. This creates several concerns:

  • Privacy Risks: Your confidential documents are exposed to third-party servers
  • Data Breaches: Server-side storage makes your files vulnerable to hacking
  • Slow Processing: Upload and download times waste your valuable time
  • Limited Access: Many tools require registration or paid subscriptions

We knew there had to be a better way. Using modern web technologies like the Web Crypto API and PDF manipulation libraries, we developed a solution that processes everything locally in your browser. No uploads. No servers. No compromises.

How PDF2Locker Works

PDF2Locker leverages cutting-edge browser technologies to perform military-grade encryption entirely on your device:

JavaScript Encryption

We use advanced JavaScript libraries to handle PDF manipulation and AES-256 encryption directly in your browser.

Web Crypto API

Browser-native cryptographic functions ensure secure and standardized encryption implementation.

Client-Side Processing

All operations happen locally on your device — your PDFs and passwords never touch our servers.

Standard Compliance

We follow PDF specification standards to ensure compatibility with all major PDF readers.
