Our Mission

At ShrinkMyPDF, we believe that powerful tools shouldn't come at the cost of your privacy. In an era where data breaches and privacy violations are increasingly common, we're committed to building tools that put users first—always.

Our mission is simple: provide the best free PDF compression tool that never compromises your security or privacy. Every file you process stays on your device. We don't track, store, or have any access to your documents. What you compress is yours alone.

Why We Built ShrinkMyPDF

The idea for ShrinkMyPDF came from a frustrating experience we all share: needing to compress a PDF quickly, only to find tools that require uploading sensitive documents to unknown servers. We asked ourselves: "Why should reducing file size require sacrificing privacy?"

Modern web technologies like WebAssembly and advanced JavaScript libraries make it possible to perform complex operations entirely in the browser. We leveraged these innovations to create a tool that's:

  • Client-Side First: All processing happens on your device using cutting-edge browser technology
  • Zero-Knowledge: We literally cannot access your files—they never leave your computer
  • Always Free: No freemium models, no hidden fees, no artificial limitations
  • Open Philosophy: We believe in transparency and plan to open-source our compression algorithms

How Client-Side Compression Works

Traditional online PDF tools upload your file to a server, process it, then send it back. This creates multiple privacy and security risks:

  • Your files traverse the internet, potentially exposing sensitive data
  • Server-side processing means files could be stored, analyzed, or leaked
  • Third parties may have access to your documents
  • Network failures can result in data loss

ShrinkMyPDF eliminates these risks entirely. When you select a PDF, our JavaScript code—running directly in your browser—analyzes the file structure, optimizes images, removes redundant data, and recompresses streams. The optimized PDF is then generated locally and offered for download. No network requests, no server uploads, no data leaving your device.

Our Technology Stack

We built ShrinkMyPDF using state-of-the-art web technologies:

PDF-Lib

A powerful JavaScript library for creating and modifying PDFs entirely in the browser

Our Commitment to You

As we continue developing ShrinkMyPDF, we pledge to:

  1. Never Compromise Privacy: All tools will remain client-side. We will never introduce server-side processing for compression.
  2. Stay Free Forever: ShrinkMyPDF will always be free. No subscriptions, no paywalls, no premium tiers.
  3. Remain Ad-Free: We won't clutter the experience with ads. Your focus should be on your work, not distractions.
  4. Be Transparent: We'll document how our tools work and share knowledge with the community.
  5. Listen to Users: Your feedback shapes our roadmap. Tell us what you need, and we'll build it.

What's Next?

ShrinkMyPDF is just the beginning. We're exploring additional privacy-focused, browser-based tools including:

  • PDF merger and splitter
  • PDF to image converter
  • PDF encryption and password protection
  • Image compression tools
  • Document format converters

All with the same philosophy: your data stays on your device, always.
