What makes a good PDF to Markdown converter?

A good converter does three things:

1. Preserves document structure — headings become #, lists become -, tables stay as Markdown tables
2. Cleans PDF noise — removes repeated page numbers, headers, footers, and broken line wraps
3. Produces reusable output — the .md file works in Obsidian, VS Code, GitHub, and AI tools without manual cleanup

Most converters fail at step 2. They extract text but leave you with fragmented sentences and page chrome mixed into the content.
