Why Marklune
Clean Markdown that keeps the structure
Most converters flatten your PDF into a wall of text. Marklune keeps the structure that makes documents actually usable downstream.
Layout-aware by design
Multi-column pages, headers, footnotes and figures — Marklune reads the page the way a person does, then rebuilds it as faithful Markdown.

Tables stay tables
Complex, multi-row tables become clean GitHub-flavored Markdown — cell for cell, no scrambled columns.
Heading hierarchy
H1–H6, lists and blockquotes mapped exactly, so chunking just works.
OCR for scans
Image-only and scanned PDFs are read with built-in OCR.
One API call
POST a file, get Markdown or JSON back. Batch thousands of documents with webhooks and signed URLs.

100+ languages
Unicode-clean output across Latin, CJK, Arabic and more.
Private by default
Processed in-memory and deleted within minutes. SOC 2-ready.
How it works
From any file to clean Markdown in three steps
- 01
Drop or POST your file
Drag a file into the app, paste a URL, or send it to the API. Single docs or batches of thousands — up to 2,000 pages each.
- 02
Marklune reads the layout
Our engine detects columns, tables, headings and figures — and runs OCR on anything scanned — then reconstructs the document’s structure.
- 03
Get clean Markdown in seconds
Receive clean Markdown or structured JSON, ready to chunk, embed and drop into your RAG pipeline, notes app or knowledge base.
