Markdown preview
Write Markdown on the left and see a live HTML preview on the right. A small inline converter handles common syntax — no CDN libraries, no network calls, nothing leaves your browser.

How the preview works
Your text is parsed line-by-line in JavaScript: fenced code blocks are extracted first (content is HTML-escaped), then headings, horizontal rules, lists, and blockquotes. Remaining lines form paragraphs. Inline passes turn **…**, *…*, backticks, and Markdown links into safe HTML; link targets are restricted to http:, https:, mailto:, # anchors, and same-site paths starting with /.
Updates are debounced (120ms) so large notes stay responsive. There are no fetch calls for rendering — the converter is bundled inline on this page.
Common use cases
- README sanity check — verify headings, lists, and code fences before pushing to GitHub.
- Support macros — paste canned Markdown replies and confirm formatting before sending.
- Changelog drafts — preview bullet lists and nested structure for release notes.
- Internal wikis — quick visual pass on prose-heavy pages without running a static site generator.
- Email-to-HTML rough pass — see how bold and links render (then paste into your ESP).
- Teaching Markdown — pair source and rendered output for workshops.

FAQ
Is my Markdown sent to your servers?
No. Conversion runs in JavaScript in your tab. No fetch calls are made for preview.
Is this full CommonMark?
No. It is a small subset for quick README and note previews: headings, paragraphs, lists, blockquotes, fenced code blocks, horizontal rules, and common inline syntax.
Is this GitHub-Flavored Markdown?
Only partially. Tables, task lists, and autolink extensions are not implemented. The goal is a fast, trustworthy preview for notes and README-style text.
Does the preview block dangerous links?
Link targets are restricted to http, https, mailto, hash anchors, and same-site paths starting with /. javascript:, data:, vbscript:, and protocol-relative URLs (//…) are dropped. Link labels and inline code are HTML-escaped so angle brackets cannot inject markup.
