How do I convert a PDF to Markdown?
Upload your PDF, and DocDigest parses it with Docling — a layout-aware engine that preserves headings, paragraphs, tables, and code blocks. You get a single .md file ready to paste into Claude, ChatGPT, Cursor, or a RAG pipeline.
Why convert PDF to Markdown for LLMs?
PDFs are designed for printing, not for token-efficient prompting. Markdown is compact, preserves structure with simple syntax, and tokenizes far more predictably across GPT-4o, Claude, and Gemini — giving you more useful context per token.
Does it handle tables and scanned PDFs?
Yes. Tables come out as Markdown grids, not OCR mush. Scanned PDFs are supported through the OCR option on Pro and Business plans, with per-page confidence reporting.
Is the free converter limited?
The free tier covers most one-off conversions (3M tokens / month). For batch folder conversion, OCR on scanned docs, API access, or files over 20 MB, see the Pro and Business plans.
How accurate is the conversion?
DocDigest uses IBM's Docling under the hood — the same engine used in production document AI pipelines. Headings, lists, tables, and code blocks are preserved at far higher fidelity than copy-paste from a PDF viewer or naive pdf2txt.
DocDigest compiles entire folders, ZIPs, and mixed PDF/DOCX/Markdown sets into one token-aware digest.
