Markdown is the lightweight writing format that powers GitHub READMEs, Reddit comments, Discord chats, Notion docs, static-site blogs, AI chat exports, and most modern note-taking apps. Tooloogle's Markdown category gives you the everyday utilities you need to write, preview, and convert Markdown without installing an editor or signing into anything.
Paste raw HTML — from a webpage, a CMS export, a chunk of email, or a Confluence page — and get clean GitHub-flavoured Markdown out. Headings, lists, links, code blocks, tables, blockquotes, and inline formatting are preserved faithfully so you can move content from a rich editor to a Markdown-based blog, README, or docs site in seconds.
Turn Markdown notes into ready-to-publish HTML you can drop into any CMS, email template, or static page. Common Mark, GFM tables, footnotes, task lists, and fenced code blocks are all supported.
A two-pane editor with Markdown on the left and rendered preview on the right. Perfect for drafting README files, writing blog posts, taking lecture notes, or learning Markdown syntax. Output mirrors what GitHub and most documentation sites will render.
Markdown is portable, future-proof, version-control friendly, and faster to type than HTML or rich-text. Once you learn the half-dozen syntax characters (#, *, -, [](), ```), you can write in any plain-text editor and publish anywhere — from GitHub to Substack to a personal blog. It also plays nicely with AI tools: ChatGPT, Claude, and Gemini all output Markdown natively, so converting their replies into clean HTML or vice-versa is a daily workflow.
Developers writing README.md, CHANGELOG.md, and GitHub issues.
Technical writers maintaining MkDocs, Docusaurus, Hugo, or Jekyll sites.
Bloggers drafting posts in Markdown for Ghost, Substack, or Hashnode.
Students taking lecture notes that need to live as both plain text and printable PDFs.
AI power-users copying ChatGPT/Claude/Gemini answers into rich-text editors.
Content teams migrating articles between CMS platforms.
Every Markdown tool here runs entirely in your browser — nothing is uploaded, logged, or sent to a server. Your draft README, your AI chat export, your client memo: none of it ever leaves your machine. That also means the tools work offline once loaded and respond instantly even on slow connections.
Start with the HTML ↔ Markdown converters if you're migrating content, or with the live previewer if you're drafting from scratch. Bookmark any tool for one-click access — you'll come back to these often.
