Live Markdown editor with instant rendered preview. Write or paste Markdown on the left to see HTML output on the right.
inline code.This is a blockquote.
Use # for H1, ## for H2, and ### for H3. Each heading level creates a progressively smaller heading. Use H1 for the page title, H2 for major sections, and H3 for subsections.
Wrap text in **double asterisks** for bold or *single asterisks* for italic. You can combine them: ***bold italic***. For inline code, wrap in `backticks`.
Start lines with - or * for unordered (bullet) lists. Use 1. 2. 3. for ordered (numbered) lists. Indent with two spaces to create nested lists.
Create links with [link text](https://url.com). Add images with . Block quotes use > at the start of a line.

Markdown was created by John Gruber and Aaron Swartz in 2004 with the goal of being readable as-is in plain text, while also converting cleanly to HTML. The name is a play on 'markup language'. Today Markdown is used everywhere from GitHub READMEs and Stack Overflow answers to Notion, Slack, Discord, and Reddit comments.
Markdown has a common core but different applications support different extensions, sanitisation rules, and line-break behaviour. This preview is useful for checking the basic structure, but confirm tables, task lists, footnotes, embedded HTML, and links in the system that will publish the document.
Markdown can contain links and, depending on the renderer, raw HTML. A production site should parse and sanitise it before displaying user-submitted content, including filtering scripts, unsafe URLs, and dangerous attributes. Use this preview to inspect formatting, not as a security boundary or a replacement for server-side sanitisation.
Leave a blank line between paragraphs for a new paragraph. For a deliberate line break, follow the conventions of your target renderer, which may accept two trailing spaces or an explicit break. Headings, lists, blockquotes, and code fences are easier to maintain when you leave a little whitespace around them.
Check that the link uses matching brackets and parentheses, that the destination is complete, and that punctuation has not been included accidentally. Relative links are resolved from the page where the Markdown is published, so a path that works in a preview may fail elsewhere. Open the rendered link and verify its destination before publishing.
