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.
