Markdown Preview
Write Markdown on the left, see rendered HTML on the right, live as you type. Headings, lists, code, tables, quotes and links all supported.
What the tool does
Markdown is the plain-text formatting language used by GitHub, Reddit, Discord and most docs. This editor renders it to HTML as you type, so you can check formatting before pasting it into a README, comment or CMS.
Supported syntax
# headings, **bold**, *italic*, - lists, 1. numbered lists, `code` and fenced code blocks, > quotes, [text](url) links,  images, --- rules, and pipe tables.
Worked example
Type ## Hello and the preview shows a level-2 heading reading Hello. Type - one\n- two and you get a bullet list.

Frequently asked questions
What is markdown?
A lightweight markup language that formats plain text with simple characters. # makes headings, ** makes bold, - makes lists. It converts cleanly to HTML.
Where is markdown used?
GitHub READMEs and issues, Reddit comments, Discord messages, Stack Overflow, Jupyter notebooks, and static site generators.
Can I copy the HTML?
The preview pane shows the rendered result. For raw HTML output you can use your browser's inspector, or paste the markdown into any converter.
Is my text sent to a server?
No. Rendering happens locally in your browser, so drafts never leave your device.
