Could you build this?

Partial Merge, split, compress, and basic conversions run in the browser via WebAssembly libraries, but high-fidelity PDF-to-Office conversion and OCR quality are hard pieces that vibe coding alone won't match.

What it would actually take: Use a front end that loads WebAssembly builds of PDF engines (for example qpdf or MuPDF) and an OCR engine such as Tesseract.js, with a Web Worker pipeline to keep the UI responsive. The hard part is conversion fidelity for complex layouts, fonts, and tables, plus memory limits on large files in the browser. Achieving parity with commercial converters requires specialists in PDF internals and document-layout processing.
