Could you build this?
Partial Wrapping existing open-source WebAssembly libraries into a web UI is possible, but compiling and coordinating specialized media/file manipulation WASM tools directly in-browser requires deeper Systems/Wasm toolchain knowledge.
What it would actually take: The stack relies on compiling native C/C++/Rust libraries (like FFmpeg, ImageMagick, or PDFium) to WebAssembly via Emscripten or wasm-pack. The primary difficulty lies in memory management, multi-threaded Web Workers, and handling large binary streams in browser sandboxes without crashing client memory.
