Why are client-side WebAssembly tools safer for private PDFs?
When signing NDAs, extracting OCR text from tax receipts, or stripping EXIF GPS data from family photos, most free websites upload the file to a remote server. How does in-browser WebAssembly execution protect document privacy?

With client-side WebAssembly (like pdf-lib, Tesseract WASM, and ONNX WebGPU/WASM), your file stays inside your browser RAM sandbox. Zero bytes are transmitted over the network in HTTP POST payloads, making data breaches or third-party cloud retention impossible.
