# pdfmarkdown.app

> pdfmarkdown.app is a free, browser-based converter between PDF and Markdown. Every conversion runs entirely in the browser — files are never uploaded to a server and there is no cloud API. The primary focus is high-fidelity PDF → Markdown (tables, formulas and images preserved); a Markdown → PDF editor is the secondary tool.

pdfmarkdown.app is made for people who need clean, AI-ready Markdown out of PDFs — researchers, Obsidian and PKM users, and anyone feeding documents to AI tools. Because it runs client-side, it also suits confidential documents that must stay on the user's own device.

Key facts:
- Free, no signup, nothing to install.
- Runs 100% in the browser; files stay on the user's device — no upload, no cloud API.
- PDF → Markdown preserves tables, formulas (LaTeX / math) and images, and shows the conversion side-by-side so the result can be checked before it is trusted.
- Markdown → PDF supports themes, KaTeX math, code, images, multi-file (.zip) merge with a contents page, and smart page breaks that keep tables and code blocks whole.

## Tools
- [PDF to Markdown converter](https://pdfmarkdown.app/): convert any PDF to clean Markdown in the browser.
- [PDF to Markdown for Obsidian](https://pdfmarkdown.app/pdf-to-obsidian-notes): convert a PDF into a Markdown note Obsidian can search, link and feed to AI. A PDF sits in a vault as an attachment whose text is never indexed, so Obsidian's search can't see inside it; converting it to Markdown puts every word into search, backlinks and the graph, and images come across too.
- [Markdown to PDF converter](https://pdfmarkdown.app/markdown-to-pdf): turn Markdown into a polished PDF.
- [PDF to Images extractor](https://pdfmarkdown.app/extract-images-from-pdf): pull the figures out of a PDF as PNG files, in the browser, with chart axis labels kept and figures the PDF split rejoined.

## Guides

- [Why AI can't read your PDFs](https://pdfmarkdown.app/blog/why-ai-cant-read-your-pdfs): why PDFs come out scrambled for AI, and how clean Markdown fixes it.
- [Best PDF to Markdown Tools in 2026: 9 Converters Tested on Real Documents](https://pdfmarkdown.app/blog/best-pdf-to-markdown-tools): a hands-on benchmark of MinerU, Marker, Mathpix, Docling, MarkItDown, PyMuPDF4LLM, CloudConvert, pdf2md and pdfmarkdown.app on five deliberately hard documents (research paper, Japanese financial report, US legal brief, dense data tables, and a scan), scored for AI-readability, with each tool's real strengths, weaknesses and silent errors, plus the full test set and raw outputs published.
