About Markdown Editor & Preview

The Markdown Editor and Preview lets you write Markdown and see the formatted result at the same time. Headings, lists, links, bold and italic text, quotes and code are rendered as you type.

Markdown is used in documentation, README files, blog drafts and note-taking apps because it is easy to write and easy to read. This tool is a quick place to draft or check Markdown before you publish it elsewhere.

Markdown lets you write structured text with simple symbols and turn it into headings, lists, links and code blocks. The editor shows a live preview as you type, so you can see how the formatting will look before you publish.

It suits README files, notes, documentation and blog drafts. Because Markdown is plain text, your content stays portable and easy to move between platforms.

Questions & answers

Frequently Asked Questions

What is Markdown?
Markdown is a lightweight way to format text using plain characters, such as # for headings and asterisks for emphasis.
How do I make a heading?
Start a line with one to six hash symbols followed by a space. More hashes create a smaller heading.
How do I add a link?
Write the link text in square brackets followed by the address in parentheses, like [text](https://example.com).
Why does my preview differ from another platform?
Markdown has several flavours, so some features such as tables or task lists may render differently between platforms.
Can I use HTML inside Markdown?
Some platforms allow it, but this preview may sanitise or ignore unsafe HTML for security reasons.
Is my text saved?
No. The preview works in your browser and your content is not uploaded.
