// About this tool
Markdown Preview
This tool renders Markdown to HTML live, entirely in your browser, using a CommonMark-compliant parser. Type on the left and see the rendered result on the right, styled the same way posts on this site are.
Switch the preview to HTML mode to see and copy the generated markup — useful for pasting into a static site, an email, or anywhere else that accepts raw HTML.
Everything runs locally — your Markdown is never uploaded, and by default the parser doesn't execute raw HTML embedded in the input, so pasting untrusted content stays safe to preview.
// When to use it
Preview a README before committing
Paste a README draft and check headings, lists, and code blocks render the way you expect.
Draft a blog post outline
Sketch a post in Markdown and see it rendered with real typography before moving it into your CMS.
Convert Markdown to HTML for another tool
Write in Markdown, then copy the generated HTML for a place that only accepts raw markup.
// Questions
Is my Markdown uploaded to a server?
No. Parsing and rendering happen entirely in your browser. Nothing is sent anywhere.
Which Markdown flavor is supported?
Standard CommonMark: headings, lists, blockquotes, links, images, emphasis, and fenced code blocks. GitHub-flavored extensions like tables and strikethrough aren't supported yet.
Is raw HTML in my Markdown executed?
No. Raw HTML tags in the input are escaped rather than rendered, so pasting content from an untrusted source is safe to preview.
Can I get the HTML output instead of the rendered preview?
Yes — toggle to HTML mode to see the generated markup, and use the Copy button to grab it.
