Could you build this?

Partial Basic PDF operations (merge, split, OCR) are easily wired up with existing libraries, but client-side conversions between PDF and MS Office formats entirely within WebAssembly are extremely difficult.

What it would actually take: The application relies on WebAssembly ports of document engines like LibreOffice, MuPDF, or Poppler running inside web workers alongside Tesseract.js for OCR. The core technical hurdle is compiling complex C/C++ rendering and conversion engines to WASM, optimizing memory usage to avoid browser tab crashes on large files, and accurately polyfilling font rendering without server-side rendering. This requires low-level WebAssembly compilation, C/C++ toolchain knowledge, and deep understanding of document specifications.
