Which library did you compile to WASM for this? I doubt this is a from scratch implementation of full PDF

A fair question. There is no from scratch PDF engine here. It is @cantoo/pdf-lib, a maintained fork of pdf-lib, running client side in a Web Worker, with WebAssembly handling the heavier parts such as encryption. I am happy to go deeper on any part of it.
