Can I use it for GitHub README files?

Yes — the supported syntax is the subset READMEs are written in. Write here, check the preview, then download the .md file or copy the Markdown into your repository.

How do I make a line break without a new paragraph?

End the line with two spaces or a backslash. A blank line starts a new paragraph; a single newline inside a paragraph is treated as a space, as in standard Markdown.

Does the editor save my text?

No. Nothing is sent to a server and nothing is stored in your browser; reloading the page resets the editor to the sample. Download the .md file to keep your work.

Why does my HTML tag show as text?

Raw HTML is deliberately escaped in the preview so that pasted content cannot run scripts. Use Markdown syntax for formatting; if you need custom HTML, add it after exporting.

Made with Markdown.

Preview

Raw HTML in the source is shown as text in the preview, and links using javascript: or data: are disabled.

How to write Markdown

Markdown is plain text with a few punctuation conventions: a hash for a heading, asterisks for emphasis, a dash for a list item. It is what READMEs, wikis, issue trackers and most note apps understand. This editor renders your text as you type, so you can see the structure take shape, and exports clean HTML when you are done.

Steps

1 Type or paste Markdown in the left box. The preview on the right updates with every keystroke.
2 Use the sample as a cheat sheet: headings, bold and italic, lists, a code block, a table, a quote and a link are all in it.
3 Copy the HTML for a CMS or template, or download the document as a .md or a standalone .html file.

The syntax in one minute

Headings: # Title, ## Section, ### Subsection. Emphasis: **bold**, *italic*, ~~strikethrough~~. Lists: start lines with - or 1.; indent two spaces to nest. Links: [text](https://example.com); images: ![alt](image.png). Inline code goes in `backticks`; a code block is fenced by three backticks, optionally followed by a language name. A line of --- draws a rule, and a line starting with a right angle bracket is a quote.

Tables

A table is a header row, a separator row and data rows, with cells divided by pipes: | Name | Price |. The separator row uses dashes, and a colon on either end sets the alignment — :--- left, :---: centre, ---: right. Columns do not have to line up in the source; the renderer handles the spacing.

What the HTML export contains

Copy HTML gives you just the body markup — paragraphs, headings, lists and tables — ready to paste into a page that has its own styles. Download .html wraps that markup in a complete document with a title taken from your first heading and a small stylesheet, so the file opens readably in any browser.

Why raw HTML is not rendered

Standard Markdown passes HTML through untouched, which is convenient but turns any pasted document into a way to run scripts in the page. This preview escapes it instead: a div or script tag in the source appears as text. Links using the javascript: or data: schemes are disabled for the same reason. Your exported file is likewise free of injected code.

Markdown editing - frequently asked questions

CommonMark with the GitHub extensions people actually use: tables, strikethrough and fenced code blocks with a language label. Footnotes, task-list checkboxes and underlined (setext) headings are not supported.
