Markdown to File
pdfmarkdown.app turns any PDF into clean, AI-ready Markdown โ and it goes both ways. Everything runs in your browser, so your file never leaves your device. No signup, no upload, free.
Most converters turn a PDF into messy text: tables collapse, formulas break, figures vanish. pdfmarkdown.app is built around fidelity โ the things that usually break come through intact:
You get the original PDF and the converted Markdown side by side, and the pages it couldn't read cleanly are flagged instead of faked โ so you can trust the output before pasting it into Obsidian, your notes, or an AI tool.
It also works the other way: paste or write Markdown โ export a polished PDF.
People who live in Markdown โ Obsidian and PKM users, researchers, and anyone prepping documents for RAG, ChatGPT or Claude.

Threadstr pdfmarkdown.apppdfmarkdown.app's answer:
It's the rare PDF-to-Markdown converter that runs entirely in your browser โ your file is never uploaded โ while still preserving the things that usually break: tables, formulas (LaTeX) and figures. It's also bidirectional (Markdown โ PDF too), and it shows the original and the converted Markdown side by side, flagging pages it couldn't read cleanly instead of silently faking them.

People who live in Markdown โ Obsidian and PKM/Zettelkasten users, researchers and students โ plus anyone preparing documents for AI: feeding clean, RAG-ready text into ChatGPT, Claude or a local LLM.
pdfmarkdown.app's answer:
No upload and no signup: it's private by default and instant, with nothing leaving your device. Free tools usually mangle tables and formulas; the heavy-duty parsers (Marker, Docling, LlamaParse) are developer/API tools. pdfmarkdown.app aims for high fidelity in a zero-setup web app a non-developer can use, and lets you verify the result before trusting it.
pdfmarkdown.app's answer:
It started from frustration: every "free PDF to Markdown" tool turned real documents โ papers with tables and formulas โ into mush, and the good ones required uploading your files or wiring up a developer API. pdfmarkdown.app was built to do the conversion right inside the browser, privately, with the tables, math and figures actually surviving โ and to be honest about the pages it can't read cleanly rather than faking them.
pdfmarkdown.app's answer:
A client-side web app (Astro) that runs the conversion entirely in the browser โ no backend processing of your file. PDF parsing is done in-browser via a pdf.js-based worker, math is rendered with KaTeX, and everything happens locally so files are never uploaded.
