100% Client-Side Private

Architecture & Privacy Whitepaper

The technical principles behind our zero-cloud, 100% client-side differential engine.

1. Zero-Cloud Data Boundary Guarantee

When you upload files into PdfCompare, binary streams are parsed locally via HTML5 File APIs directly into WebAssembly memory buffers. Your data never touches a remote server. When you close the browser tab, all temporary buffers are instantly wiped by garbage collection.

2. WebAssembly Performance Multi-Threading

By compiling high-performance differential algorithms directly to WebAssembly bytecode, comparisons across multi-page documents execute on your multi-core CPU with latency under 50ms.
