pdfmd

A fast PDF-to-Markdown engine in Rust, built without dependencies.

What I built

I built a zero-dependency PDF-to-Markdown converter, including the PDF parser, DEFLATE decoder, and layout reconstruction.

Implemented the PDF reader, zlib/DEFLATE decoder, font decoding, and content-stream interpretation directly in Rust.
Reconstructed Markdown from positioned text, including headings, columns, lists, and tables; exposed the engine through a CLI and Python bindings.
Documented performance and text-fidelity benchmarks. Complex layouts and table reconstruction remain best-effort.

Conversion pipeline

$ pdfmd paper.pdf -o paper.md

PDF bytes → objects & streams
          → fonts & positioned text
          → headings, tables, Markdown
