About Markdown Previewer
Write Markdown on one side and see the rendered result update live on the other. Output is sanitized before display, so pasted content can't inject scripts or unsafe HTML.
How to use it
- Type or paste Markdown into the left pane.
- Watch the rendered preview update live on the right.
Common use cases
- Previewing a README before committing it
- Drafting a GitHub issue or pull request description
- Checking how a changelog entry will actually render
FAQ
Is the rendered output safe if I paste in HTML?
Yes. The rendered HTML is sanitized (via DOMPurify) before it's displayed, so raw HTML or script tags in your Markdown can't execute.
Can I copy the rendered HTML output?
Not currently — the preview renders live so you can check how your Markdown will look, but there's no separate "copy as HTML" export yet.
