# PDF to Markdown > Free Chrome extension that converts any PDF into clean, LLM-ready Markdown — tables, formulas, images, and OCR for scanned pages. No account, files auto-deleted. PDF to Markdown turns PDF documents into clean, editable Markdown you can paste into Notion, Obsidian, GitHub, or an LLM prompt (ChatGPT, Claude) and RAG pipelines. It runs as a Chrome extension (Manifest V3) and works with local files and direct PDF URLs. There is no sign-up: each device gets an anonymous signing key automatically and every request is cryptographically signed. ## What it does well - Real Markdown tables (not screenshots) and preserved math/formulas - OCR for scanned / image-only PDFs, including Cyrillic/Russian and English - Images embedded as base64 data URIs or replaced with clean placeholders - Live preview in rendered and raw modes, with code highlighting - Output: copy to clipboard or download a .md file ## Inputs - Drag & drop a PDF, or pick a file - Paste a direct PDF URL — it fetches and converts - One-click inline button on PDF pages in the browser - Side panel for ongoing task monitoring ## Use cases - Prepare PDF content as LLM context for ChatGPT, Claude, or RAG - Convert PDF documentation to Markdown for Notion, Obsidian, or GitHub - Extract selectable text from scanned documents (OCR) - Quickly copy formatted content out of PDFs without losing structure ## Limits - Maximum file size: 10 MB - Maximum concurrent jobs: 3 per device - Supported input: PDF only - Large or heavily scanned PDFs take longer (OCR is the slow part) ## Privacy - 100% free, no account, no login, no email - Anonymous device key (WebCrypto); every request is signed; no personal tracking - Uploaded files are processed on a secure server and auto-deleted after ~1 hour ## How it works 1. Install the Chrome extension and click its toolbar icon 2. Drag in a PDF, pick a file, or paste a PDF URL 3. Wait for conversion (queued → processing → ready); OCR takes longer 4. Copy the Markdown or download a .md file ## Links - Install: https://chromewebstore.google.com/detail/kodhbjmmdeofaecpblbfeoceglmedfmd - Website: https://pdf2md.huskyhaul.online/ - For AI & LLMs: https://pdf2md.huskyhaul.online/for-ai/ - ChatGPT (custom GPT): https://chatgpt.com/g/g-6a2faa6e09b08191910855b34d87e38b-pdf-markdown-clean-md-tables-ocr - Privacy: https://pdf2md.huskyhaul.online/privacy/ - Terms: https://pdf2md.huskyhaul.online/terms/ - Support: support.pdf2md@huskyhaul.online ## Platform - Google Chrome (Manifest V3).
