Reclaiming PDF Privacy: How WebAssembly Enables Secure Browser-Based Processing

WebAssembly enables sensitive PDF processing to occur entirely on users' devices rather than uploading to centralized servers, addressing a critical privacy gap in web-based document tools. By compiling existing C/C++ PDF libraries to WASM, developers can now move data-sensitive operations like merging, compression, and protection from the cloud to users' browsers. This shift has significant implications for privacy-conscious document handling while maintaining the speed and functionality users expect.
