About this converter

We built this tool around one principle: converting a PDF to Markdown should be instant, accurate, and private. Most online converters upload your file to a server you do not control. For contracts, research, financial documents and internal notes, that is a real problem.

So we did the opposite. This converter runs entirely in your browser using PDF.js. Your file is parsed locally and turned into clean Markdown without a single byte being uploaded. It is free, needs no account, and works even offline once loaded.

Our approach to accuracy

A PDF is a set of drawing instructions, not a structured document. We reconstruct meaning from geometry — clustering font sizes into headings, detecting lists from bullet patterns, and aligning columns into tables. It is honest about its limits: scanned PDFs are flagged rather than mangled, and OCR is on the roadmap.

What is next

We are working toward OCR for scanned documents, better multi-column handling, image extraction, and an API for developers who want to automate conversion. The architecture is built so these can ship without compromising the privacy-first core.
