The quickest way
- Pick a converter (see our tested picks below).
- Run your PDF through it to get a .md file.
- Skim the result, fix any broken tables, then paste it into ChatGPT or Claude.
Which tool should you use?
It depends on your document. For everyday files, a lightweight converter is enough. For tables, scanned pages, or complex layout, you need a stronger one. We tested the main tools on real documents so you don't have to.
Tip. The most common failure is tables with merged headers. In our tests, only Docling kept them intact, so check your tables first.
