Markdown cheat sheet

Fenced code blocks start and end with three backticks, optionally followed by a language name for syntax highlighting on sites that support it. Tables use pipes and a separator row of dashes.

Example

- A faster *search*

Why convert Markdown to HTML?

• Websites and blogs: write in Markdown, publish as HTML.
• Email newsletters: draft in Markdown and paste the HTML into your email tool.
• CMS fields that accept HTML but not Markdown.
• Documentation: preview README files before committing them.
• Learning: see exactly what HTML each Markdown feature produces.

Tips

• Leave a blank line between paragraphs, lists and headings.
• Indent nested list items by two or four spaces.
• Escape characters that Markdown would otherwise format with a backslash, such as \* for a literal asterisk.
• If you paste the HTML into a site, check its rules — some platforms strip tags like iframes or styles.

Flavours of Markdown

The original Markdown left some details undefined, so different sites made different choices. CommonMark is a precise specification that most modern tools follow, and GitHub-flavoured Markdown (GFM) adds tables, task lists, strikethrough and automatic links on top. This converter uses a GFM-compatible parser, so READMEs and notes written for GitHub, GitLab and most documentation tools convert as you’d expect. Some platforms add their own extras, such as footnotes, math or diagrams, which may appear as plain text here.

Line breaks

A single new line inside a paragraph is ignored by default. End a line with two spaces, or tick the line-break option, to force a break.

This matches how GitHub and most Markdown editors behave.

Images

Markdown images point to a URL. In the preview, images load only if the URL is publicly reachable; local file paths from your computer won’t display.

Security note

Markdown allows raw HTML, so HTML copied from untrusted sources can contain scripts. The preview here is sandboxed, but if you publish the output on a website, make sure your site sanitises user content. To show HTML code as text, escape it with the HTML entity encoder. To count words in your draft, use the word counter.
