HTML source appears here (escaped)

Paste Markdown or tap sample.

What this is for

Markdown to HTML — Convert README & Docs With Live Preview helps you format, validate, and encode before paste: works in your browser, no account needed. JSON, YAML, Base64, URLs, escapes—check here first, then ship to PRs, Slack, or configs.

  • Re-validate after every payload edit
  • Copy from the panel—nothing leaves your device until you do
  • Local run for tokens and internal data
  • Green here, then paste into production paths

Security: Fast correctness pass only—secrets still go through your team’s review.

Why convert here

Quick drafts for readme files and CMS blocks do not need a server round-trip. Escaped preview keeps random paste from executing markup while you still copy real HTML for your pipeline.

How it works

  1. Paste Markdown (headings, bold, italic, paragraphs supported).
  2. Click Convert to HTML or keep Live on.
  3. Read the stats bar for output size and rough tag density.
  4. Copy HTML then optionally minify with HTML minifier.

FAQ

  • Tables, task lists, footnotes? Not in this lightweight converter—use your static site generator or a full Markdown library for GFM.
  • Nested HTML in Markdown? User angle brackets are escaped before pattern passes; treat output as untrusted until your sanitizer runs.
  • Large documents? Turn off Live for very long files to keep the tab responsive.
