A PDF does not store paragraphs — it stores painted letters at fixed coordinates. This converter reads that text layer page by page with PDF.js and rebuilds it as flowing paragraphs inside a genuine Word .docx file, generated locally with the docx library.
The result is a document you can actually work with: correct a typo, copy a passage, reformat the text, or feed it into another workflow. That is the realistic promise of PDF-to-Word in a browser — content extraction done well.
It is equally honest about what it is not: a layout copier. Fonts, columns, tables-as-graphics and embedded images are not recreated, and a scanned page (which is just a photograph) contains no text to extract. You will find those limits spelled out below rather than discovered after the fact.
