What this markdown previewer does
Use this Markdown previewer to check how Markdown will look before pasting it into GitHub, Linear, a README, release notes, docs, or a CMS. The editor and preview sit side by side so formatting mistakes are easy to catch.
Common use cases
- Preview README sections before committing them.
- Draft changelogs, release notes, issue comments, and incident updates.
- Check headings, lists, inline code, and fenced code blocks before publishing.
- Clean up Markdown copied between tools with slightly different editors.
Accepted input formats
Headings
# Title, ## Section, ### Detail
Lists
- one, - two
Inline code
`npm run build`
Code blocks
```bash
npm run build
```
How it works
The preview runs in the browser and escapes raw HTML. It focuses on the Markdown patterns developers use most often: headings, paragraphs, lists, inline code, and code blocks.
Common mistakes
- Leave a blank line before and after lists or code blocks for more predictable rendering.
- Use fenced code blocks for commands instead of trying to preserve indentation manually.
- Do not rely on raw HTML here; the preview intentionally escapes it.
