Does Marklune handle scanned or image-only PDFs?

Yes. Scanned documents and embedded images are read with built-in OCR in over 100 languages, then converted to Markdown just like native text PDFs.

Will tables and formatting really be preserved?

Tables become clean GitHub-flavored Markdown tables, cell for cell. Headings map to H1–H6, and lists, blockquotes and code blocks are kept — so structure-dependent chunking and retrieval just work.

Is my data private and secure?

Files are processed in-memory and deleted within minutes — we never use your documents to train models. Marklune is SOC 2-ready with encryption in transit and at rest.

What can I export, and is there an API?

Export Markdown, structured JSON or HTML. Every paid plan includes a REST API with Python and Node SDKs, webhooks and batch processing for converting thousands of PDFs at once.

Is there a free plan?

Yes — 50 pages every month, free forever, no credit card required. Upgrade to Pro or Team when you need the API, higher limits and batch conversion.

Why Marklune

Markdown clean enough to feed an LLM

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.

PDF pages being parsed and transformed into a structured knowledge graph for AI

Tables stay tables

Complex, multi-row tables become clean GitHub-flavored Markdown — cell for cell, no scrambled columns.

How it works

From messy PDF to clean Markdown in three steps

01
Drop or POST your PDF
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 LLM-ready Markdown
Receive clean Markdown or structured JSON, ready to chunk, embed and drop into your RAG pipeline, notes app or knowledge base.

FAQ

Questions, answered

Plain extraction dumps a flat wall of text — columns merge, tables scramble and headings vanish. Marklune is layout-aware: it rebuilds the document as structured Markdown, so headings, lists and tables survive intact and your LLM gets clean, chunkable input.
