Convert academic PDFs to clean Markdown
Preserve complex formulas (LaTeX), scientific tables, and inline/block images perfectly. The ultimate document conversion tool for researchers and students.
Designed for Scientific & Technical Documents
Say goodbye to broken text, missing symbols, and chaotic tables. Our parser keeps everything intact.
Formulas Kept in LaTeX
Translates both inline mathematical expressions and multi-line equations into correct LaTeX ($ and $$ delimiters) compatible with KaTeX/MathJax.
Flawless Markdown Tables
Converts complex research paper tables into valid GFM Markdown tables with proper alignments, columns, and rows. Hover to copy table code instantly.
Extracted & Linked Images
Binds and extracts all figures, charts, and diagrams. Re-maps image tags to relative paths in the output Markdown, and packages them in a neat ZIP file.
Visual Split-Screen Editing & Review
Verify the translation results with our side-by-side comparative layout. Review original PDF rendering alongside translated Markdown live.
Frequently Asked Questions
What is paper2md?
paper2md is a web tool that converts academic and technical PDFs into clean Markdown, preserving LaTeX math formulas, tables, and images. It includes a split-screen editor to review the original PDF next to the converted Markdown. The free plan includes 100 page conversions every month.
How are mathematical formulas handled?
Formulas are converted to LaTeX with standard $ (inline) and $$ (block) delimiters, normalized for compatibility with KaTeX, MathJax, and Obsidian's math rendering.
Is paper2md free?
Yes. The Free plan includes 100 page conversions per calendar month with no credit card required. The Pro plan is $6.99/month for 2,000 pages, and a $2.99 Booster Pack adds 500 pages that never expire.
What are the file size and page limits?
The Free plan accepts PDFs up to 20 MB. The Pro plan raises the limit to 50 MB and supports single documents up to 1,000 pages.
What happens to my uploaded files?
Uploaded PDFs are automatically deleted within 1 day and converted outputs within 7 days. Your documents are never used to train AI models.
Can I use the output in Obsidian, Notion, or a RAG pipeline?
Yes. Math delimiters are normalized for Obsidian, tables use GitHub-Flavored Markdown, and images are extracted into a ZIP with relative paths, so the output drops cleanly into Obsidian, Notion, and LLM/RAG ingestion pipelines.
