PDF to Markdown - Convert PDFs to clean Markdown in your browser.

Most online PDF converters upload your private documents to remote servers and mess up tables and code blocks. pdftomarkdown.fyi is a 100% free, private PDF to Markdown converter that runs directly in your browser memory: 🔒 100% Client-Side — Zero file uploads, your data never leaves your device 📊 Reconstructs GFM pipe tables, headings, code & lists 🤖 Saves 70%+ tokens when feeding docs to Claude, ChatGPT & Cursor 📦 Open-source CLI

Hey Product Hunt community! 👋 I built **pdftomarkdown.fyi** out of a very real daily frustration. Whenever I needed to feed documentation, research papers, or API specs into Claude, ChatGPT, or Obsidian, raw PDFs were a nightmare: 1. They consumed 4x more tokens than necessary due to binary formatting noise. 2. Tables constantly got scrambled into unreadable blobs. 3. Every "free" converter online forced you to upload sensitive files to unknown remote servers or hit you with paywalls. I wanted a clean, instant, and privacy-first solution. ### 🛠️ How it works: Instead of sending your files to a cloud backend, **pdftomarkdown.fyi** parses the PDF layout entirely within your browser memory (WebAssembly/Canvas). • **100% Private:** Your files never leave your computer. • **GFM Tables & Code Blocks:** Analyzes typography and layout coordinates to reconstruct structured GitHub Flavored Markdown. • **Token Optimized:** Strips binary overhead, reducing LLM token consumption by up to 75%. • **No Signup / No Limits:** Free forever with no watermarks. We also built an open-source CLI (`npx pdftomarkdown`) for developers who want to batch-convert local directories. I’d love to hear your thoughts, feedback, and feature requests! What documents are you converting today? 🚀
