PDF to md: Convert PDF to Markdown with AI Precision

PDF to md is a web-based AI tool that converts PDF documents (up to 50 MB, 100 pages) into clean Markdown files, preserving tables, mathematical equations (as LaTeX), and complex multi-column layouts.

What is PDF to md?

PDF to md is a web application that takes PDF files as input and outputs Markdown (.md) text. It uses AI to analyze document structure — columns, headers, footers — then reconstructs tables row by row and converts formulas into LaTeX syntax. The platform runs in any modern browser and processes files securely, deleting them immediately after conversion. The product is developed by the team behind pdftomd.org.

Key Features

• AI Table Extraction — Identifies and reconstructs standard and nested tables into valid Markdown grid syntax, preserving row and cell structure.
• Equation Recognition — Automatically detects both inline and block mathematical formulas and converts them into LaTeX syntax.
• Multi-column Layouts — Parses complex multi-column document layouts to maintain correct reading order.
• Image Extraction — Extracts figures and images from the PDF and saves them into a separate assets folder for reference.
• Instant Preview — Provides a side-by-side view comparing the original PDF page with the generated Markdown in real-time.
• Privacy First — Uploaded files are processed on secure servers and deleted immediately after conversion; no persistent storage.

Who is it for?

• Personal Knowledge Management users — Convert books, reports, and papers into clean Markdown for use in Obsidian, Notion, or Logseq to build a searchable second brain.
• Academic Researchers — Convert research papers and technical documentation while preserving equations and table data for analysis and citation.
• Developers and Technical Writers — Transform PDF documentation into Markdown for integration with static site generators, Git repositories, or LLM training datasets.

What can you do with PDF to md?

• Build a knowledge base: Convert a collection of PDFs into Markdown files, then import them into note‑taking apps like Obsidian or Notion for full‑text search and linking.
• Prepare data for LLM training: Cleanly extract structured content (tables, headings, code blocks) from PDF documents to create high‑quality text datasets.
• Publish technical documentation: Convert product manuals, API guides, or white papers into Markdown that can be rendered on a website or documentation platform.

How does PDF to md work?

The conversion follows a 4‑step process: (1) Secure Upload — drag and drop a PDF file (max 50 MB, 100 pages). (2) AI Layout Analysis — the AI identifies columns, headers, footers, and reading order. (3) Element Reconstruction — tables are parsed into valid Markdown grid, formulas convert to LaTeX, and images are extracted. (4) Export & Download — preview the result side‑by‑side, then download the final Markdown file or a zip package.

Pricing

PDF to md uses a freemium model. New users receive 20 free credits upon sign‑up. Each conversion may consume credits depending on file size or page count; a paid upgrade is available for higher usage. See the pricing page for details.

Is PDF to md really free to use?

New users get 20 free credits on sign‑up. After that, additional conversions require a paid plan. The free tier allows you to test the tool with small documents.

How accurate is the table conversion?

The AI reconstructs table structure row by row and cell by cell into standard Markdown tables. It handles both standard and nested tables, as well as multi‑column layouts.

What happens to my uploaded files?

Files are used only for the AI conversion and are deleted from the servers immediately after processing. No data is stored or shared.
