Could you build this?
Partial A basic PDF-to-EPUB tool is vibe-codeable, but accurately reconstructing reading order, flowable text, semantic headings, and clean tables completely client-side in the browser is notoriously difficult due to PDF layout complexity.
What it would actually take: True PDF reflow requires complex document layout analysis (heuristics or computer vision/OCR models like LayoutLM compiled to ONNX Web) to infer document hierarchy, reading order, and column breaks from absolute-positioned PDF glyphs. The stack would use PDF.js or native WASM-compiled Poppler/MuPDF to extract raw geometries, an in-browser spatial layout heuristic engine, and JSZip to package valid, accessible EPUB3 structures.
