Structured PDF to Markdown
Paragraph reflow for hyphenated breaks, suppressed arXiv/DOI false headings, optional page breaks for research PDFs, and an RAG/embedding-safe mode—all in-browser. Prefer the simpler PDF to Markdown for quick exports.
Preparing documents for RAG or agents?
Use structured Markdown, OCR, API keys, and MCP when PDF text has to feed search, embeddings, or internal workflows.
How It Works
Step 1: Choose a Typography Profile
Developer (clean prose), Academic (preserve `---` between pages like audit logs), or RAG/Embeddings (collapse short PDF lines).
Step 2: Run Local Typography Pass
Join hyphen-split words, flatten bogus arXiv/DOI headings, dedupe repetitive page banners, bold figure/table captions where detected.
Step 3: Export Markdown + API parity
Copy to Obsidian/Git or point automated jobs at POST /api/v1/pdf-structured-markdown — same presets as this page.
Why Use This Tool
- Feeds LLM chunkers tighter paragraphs with fewer dangling hyphen shards
- Safer archival for research decks & legal PDF bundles that repeat running headers page-to-page
- Matches Bing/Google intent for structured PDF Markdown + API tooling keywords
- Pairs cleanly with OCR PDF flows when the selectable text layer fails
Common Use Cases
Ship Markdown release notes sourced from OEM PDF bundles, hydrate internal RAG with conference papers offline, hydrate developer portals from vendor PDF snapshots, normalize legal exhibits before hashing them across environments.

Frequently asked questions
What is structured PDF to Markdown?
It runs the upgraded ExactPDF typography pipeline — reflowing hyphen breaks, demoting bogus arXiv/DOI headings, deduping repeated page banners, emphasizing figure/table captions — then exports Markdown. Use it for specs, textbooks, developer PDFs, and arXiv-style papers.
How is this different from regular PDF to Markdown?
The classic tool optimizes headings + lists quickly. Structured mode adds prose cleanup for long documents plus three explicit profiles (developer, academic with page separators, rag for embeddings chunking hygiene). Same privacy model: conversions run in your browser for the preview path.
Does ExactPDF expose this via REST API?
Yes. Authenticated callers can POST a text-layer PDF with mode=developer|academic|rag and output_format=json|markdown|jsonl to /api/v1/pdf-structured-markdown. JSON includes page and deterministic chunk provenance. OCR is not run and tables remain reading-order text.
