How to preview Markdown
Write Markdown on one side and see it rendered on the other, then copy the HTML or save the source.
- 01
Type or paste Markdown on the left
The editor opens with a sample showing most of the supported syntax. Replace it with your own text, or press Reset to bring the sample back.
- 02
Watch the preview update as you type
Split view shows source and preview side by side. Source and Preview give either one the full width, which is easier on a phone.
- 03
Copy the HTML or download the .md file
Copy HTML puts the rendered markup on your clipboard for a CMS or email editor. The .md button saves your source as document.md.
Which Markdown syntax renders
The preview uses a small built-in renderer rather than a full Markdown library, so it covers the syntax people use most and skips the rest. Here's exactly what it handles:
| You type | You get | Status |
|---|---|---|
| # to ###### | Headings, levels 1 to 6 | Supported |
| **bold**, *italic*, ***both*** | Emphasis | Supported |
| ~~strike~~ | Strikethrough | Supported |
| `code` | Inline code | Supported |
| ```js … ``` | Fenced code block, with a language-js class | Supported |
| [text](url) | Link, opens in a new tab | Supported |
|  | Image | Supported |
| - item, * item, + item | Bulleted list | Supported, one level only |
| 1. item | Numbered list | Supported, one level only |
| | a | b | | Table with a header row | Supported |
| > quote | Blockquote | One line per quote |
| --- | Horizontal rule | Supported |
| - [ ] task | Task list checkbox | Not supported |
| <div>raw HTML</div> | Inline HTML | Shown as text, not rendered |
Raw HTML is shown as text on purpose. Everything you type is escaped before it's rendered, so a pasted <script> tag can't run in the preview.
Where it differs from GitHub
GitHub follows the CommonMark spec plus its own extensions, so a few things render differently there. The biggest one is line breaks. Here, every line becomes its own paragraph. On GitHub, lines next to each other join into one paragraph, and you need a blank line between paragraphs. Write your README with blank lines between paragraphs and it will look right in both places.
Nesting is the other gap. Indenting a list item under another doesn't create a sub-list here, and a blockquote spanning several lines needs > at the start of each line. GitHub also adds task-list checkboxes, footnotes, emoji shortcodes such as :tada: and automatic links for bare URLs. For a final check of a complex README, preview it on GitHub itself before you merge.
Writing a table that renders
Tables are where Markdown trips people up most. You need three things: a header row, a separator row, and the body rows, each starting and ending with a pipe. For example, | Plan | Price | then | --- | --- | then | Basic | ₹499 |. The separator row needs at least three dashes in each cell.
Colons in the separator, such as :---: for centred text, are accepted but alignment isn't applied in this preview; GitHub does apply it. A pipe inside a cell ends the cell early, so write it as \| if you need a literal pipe. And keep the whole table without blank lines between rows, or it breaks into separate paragraphs.
What people use it for
Drafting a README
Write headings, install steps and code samples, check the layout, then paste the source into your repository.
Turning notes into HTML for a CMS
Write in Markdown, copy the HTML and paste it into a CMS's HTML or code view, keeping headings and links intact.
Learning the syntax
Edit the sample and watch what each symbol does. It's a quick way to learn the 90% of Markdown you'll actually use.
