HTML to Markdown Converter - Markdownizer

Webpage to Markdown for ChatGPT, Claude & Gemini. Convert HTML to Markdown with tables, code & links preserved — privacy-first.

HTML to Markdown Converter - Markdownizer turns the current webpage into clean Markdown for ChatGPT, Claude, Gemini, and any other LLM. Get better context than raw copy-paste, noisy HTML, screenshots, or a bare URL: headings, tables, lists, links, and code blocks survive the trip from browser to prompt. ⚡ WHAT MARKDOWNIZER DOES - Converts the active page into Markdown on demand. - Preserves useful structure: headings, lists, tables, links, and code blocks. - Copies the Markdown to your clipboard or downloads it as a .md file. - Downloads the page together with its images as a ZIP, with the Markdown's image links rewritten to local files in an images/ folder. - Shows a capture preview so you can verify what will be converted. - Captures the full page when the smart selection is too narrow. - Gives LLMs text-first context instead of relying on screenshot interpretation. 💡 WHY CONVERT WEBPAGES TO MARKDOWN FOR AI Copy-paste flattens structure. Screenshots force the model to guess. A bare URL cannot be fetched when a page is private, logged-in, or JavaScript-heavy. Markdownizer converts the page into structured text your AI can actually read: clean, token-efficient context that keeps tables aligned, code formatted, and links intact - ready to paste into ChatGPT, Claude, Gemini, your notes app, or your coding workflow. 🎓 FOR STUDENTS Turn assignment briefs, course pages, assignment rubrics, and research readings into clean Markdown while logged in to your learning platform. No copying tables cell by cell, no screenshots of a rubric grid: headings, lists, tables, links, and code survive the conversion for notes and AI-assisted study. 💻 FOR DEVELOPERS AND AI POWER USERS Prepare API docs, documentation pages, and code samples as LLM context or RAG source material. Use it for pages an LLM cannot reach - private URLs, logged-in dashboards, and JavaScript-rendered apps. Keep code blocks formatted with their language context, and download the page's images alongside the Markdown when you need the complete artifact locally. 🔒 PRIVACY BY DESIGN Markdownizer tokenizes readable page text locally in your browser before conversion. The backend receives only a structural page skeleton; your readable text never leaves your browser as readable text. The returned Markdown skeleton is rehydrated locally. Markdownizer does not store readable page text, final Markdown output, full page URLs, or raw HTML skeletons in analytics. Operational analytics are limited to running and improving the service. 📋 HOW TO USE 1. Open the page you want to convert. 2. Click the Markdownizer extension icon. 3. Press start. 4. Copy the clean Markdown or download a .md file - or enable "Include images" to download the page with its images as a ZIP. 5. Paste it into ChatGPT, Claude, Gemini, your notes app, or your coding workflow. ❓ FAQ Will my tables stay aligned? Yes - Markdownizer preserves table structure so rows and columns stay readable after conversion. Will code blocks keep their formatting? Yes - code blocks and their language context are preserved, so snippets stay paste-ready. Can it capture pages I'm logged in to? Yes - Markdownizer converts the page as you see it in your browser and never bypasses authentication or access controls. Does my content leave my browser? Readable page text stays in your browser. Only a structural skeleton is sent for conversion, and no readable text, output, or full page URLs are stored. How does the ZIP image download work? Enable "Include images" and Markdownizer downloads a ZIP containing your Markdown, a README, and the page's images with local paths. The bundle is built locally with live progress, and the download continues even if you close the popup. A one-time optional site access permission is requested only when you first enable image bundling. Why not just give the LLM the URL? Many pages are private, logged-in, or JavaScript-heavy, so an LLM cannot fetch them. Converting the page in your browser captures exactly what you see. 🆕 RECENT UPDATES - Image bundling: download page images alongside your Markdown as a ZIP with local image paths.
