How to use the Markdown editor
- Type Markdown on the left — the preview on the right updates as you write.
- Use the toolbar for bold, headings, links, lists, task lists, quotes, code and tables. Select text first to format it.
- Open an existing
.mdfile or drop it onto the editor. On a phone, switch between Edit and Preview. - Download the result as
.md, export it as an HTML page, or copy the Markdown or the rendered HTML.
Write a GitHub README with a live preview
The example document is a typical README: a title, a short description, installation and usage sections with code, an options table and a task list for the roadmap. Edit it, check the preview, then download it as README.md. Tables, task lists and strikethrough follow GitHub Flavored Markdown, so the preview looks close to how GitHub shows the file.

To simply read a Markdown file, the Markdown reader shows it as a clean document with a table of contents. Need the HTML source for a website or CMS? Use the Markdown to HTML converter, and tidy the result with the HTML formatter. For plain notes without formatting, the online notepad is simpler.
Frequently asked questions
- Which Markdown syntax is supported?
- CommonMark plus GitHub Flavored Markdown: headings, bold, italic, strikethrough, links, images, ordered and unordered lists, task lists, blockquotes, inline code, fenced code blocks, tables and horizontal rules.
- Is my text saved?
- Yes, in your browser only. The editor autosaves to local storage, so your draft is still there when you come back on the same device and browser. Nothing is uploaded; use Download .md to keep a copy.
- Can I use HTML inside Markdown?
- Common, harmless tags such as <kbd>, <details>, <sup> or <img> with a width are shown in the preview. Scripts, event handlers, iframes, forms and javascript: links are removed, so a pasted document can't run code on this page.
- Can it format or clean up my Markdown?
- The toolbar formats text for you — bold, italic, headings, links, lists, task lists, quotes, code and tables — so you don't have to remember the syntax. It doesn't rewrite a whole document automatically.
- How do I write a GitHub README here?
- Start from the example, which is laid out like a typical README, edit it with the live preview, then download the result as README.md and commit it to your repository.
