A local converter for papers and notes
PDF to MD Converter is a free online tool that turns PDFs into Markdown without uploading the file. It restores two-column academic layouts, extracts GFM tables, and converts LaTeX math, with a fast in-browser parse path and an AI vision OCR path.

What you can convert

- GFM tables lifted out of the PDF instead of flattened text
- LaTeX-style math kept beside the surrounding prose
- A local parse for text PDFs, plus AI vision OCR when the page is a scan
- Markdown can also be exported back to PDF when you need a shareable file
Where to start
Use the in-browser converter
Researchers, students, and developers can edit the Markdown, diff it, and drop it into notes. The tool is free, and files stay on the device. Contact: Neo Wang.
