About Markdown Editor
Write Markdown on the left and watch the rendered preview update as you type. Supports headings, tables, code blocks, and images, plus .md file upload. Draft READMEs and docs without leaving your browser.
What is Markdown?
Markdown is a lightweight markup language that uses plain-text formatting syntax. John Gruber created it in 2004 as a way to write HTML without writing HTML. You use simple characters like # for headings, * for emphasis, and - for lists. Markdown files use the .md extension. Developers write them for GitHub READMEs, documentation sites, and blog posts.
How to use this editor
Type or paste Markdown in the left panel and the rendered HTML appears on the right in real time. You can also upload a .md file directly. The editor supports all standard Markdown syntax including headings, bold, italic, links, images, code blocks, tables, and lists. Use it to draft READMEs, preview documentation, or convert Markdown to readable HTML before copying it somewhere else.
