Pandoc is awesome for converting text-based formats and markup files, but from my knowledge it doesn’t cover some of the more specialized PDF operations (like merging, splitting, rotating pages, etc.) or handling complex office formats with embedded elements. My tool aims to provide a quick, browser-based way to handle all those PDF tasks—no installation or command-line usage required.
Thanks for asking! I don’t reimplement those formats myself—LibreOffice does the heavy lifting for parsing and converting office documents with embedded elements. That way, I just leverage an existing engine instead of reinventing the wheel, and it helps preserve formatting as accurately as it can.
I’m not actually loading LO into the browser—those parts run on the server side, so you still need an internet connection for complex document conversions. The offline functionality mostly covers simpler features like merging PDFs or converting images to PDF with WebAssembly libraries in the browser. For MS Office files or other advanced formats, I rely on LO’s server-side engine to handle parsing and conversion
