What is a Markdown Preview?
Markdown is everywhere — READMEs, GitHub issues, documentation, CMS fields — but you rarely see the result until publishing. This preview renders as you type.
Rendering happens locally and the output is sanitized, so pasted markdown can’t inject scripts into the page.
How to use the Markdown Preview
- Type or paste markdown on the left.
- Read the rendered preview on the right.
- Iterate until it looks right, then publish where it’s going.
Frequently asked questions
Which markdown flavor is supported?
CommonMark with common GitHub-style extensions like tables and fenced code blocks.
Is the HTML output safe?
The rendered HTML is sanitized (script tags and event handlers stripped) before display.
Can I copy the generated HTML?
Copy from the preview, or paste the markdown into your target platform — most render it natively.
Is my writing uploaded?
No — rendering is local.
