About Markdown to HTML
Markdown to HTML is a free browser-based tool for converting Markdown-formatted text into rendered HTML. Type on the left, watch the preview update live on the right — or switch to HTML source view to grab the raw output.
Markdown is a lightweight markup language that lets you format text with plain punctuation: **bold**, *italic*, # for headings, - for lists, and so on. Since the syntax is closer to how people actually write, it's the format of choice for README files, blog drafts, technical docs, GitHub issues, chat platforms (Discord/Slack), Reddit posts, and static site generators.
Our converter supports full GitHub Flavored Markdown: tables, task lists (- [x]), fenced code blocks with syntax highlighting, strikethrough (~~like this~~), and autolinks. Everything runs in your browser via marked.js — no server round-trip.
100% client-side: Rendering happens in your browser via marked.js, a battle-tested CommonMark parser. Nothing you write is uploaded, seen, or stored by us. Safe for private drafts, meeting notes, or unpublished blog posts.
How to use Markdown to HTML
Paste or type Markdown
Drop your Markdown text into the editor. Load Sample if you want to try it first.
Watch the live preview
Rendered HTML appears in real time. Switch view modes to see just the preview or grab the raw HTML source.
Copy or download
Copy HTML to clipboard, download the rendered .html file, or save your Markdown source as .md.
Key Features
Live preview as you type
Every keystroke re-renders the preview. See exactly how your Markdown will look before you copy the HTML anywhere.
GitHub Flavored Markdown (GFM)
Tables with alignment, task lists (- [x] done), strikethrough (~~text~~), automatic URL linking. All toggleable if you need strict CommonMark.
Syntax-highlighted code blocks
Fenced code blocks with a language identifier (```js) get syntax coloring via highlight.js — GitHub-style, right in the preview.
Three view modes
Split — editor + preview side by side. Preview only — see what recipients will see. HTML source — grab the raw HTML to paste anywhere.
Download as .html or .md
Save the rendered HTML as a standalone file (with basic styling included) or download your Markdown source for archiving.
Copy HTML to clipboard
One click puts the HTML output on your clipboard — ready to paste into your CMS, email, or code file.
Line breaks toggle
Turn on "Line breaks as <br>" if you want single line breaks preserved (like GitHub comments) instead of the strict CommonMark rule where you need two spaces or a blank line.
Common Use Cases
- Draft a README, then paste the rendered HTML into your CMS or documentation site
- Convert blog drafts written in Markdown to HTML for platforms that don't accept MD directly
- Preview how a GitHub issue or PR description will look before you post
- Turn meeting notes or todos into a shareable HTML page
- Convert Discord/Slack-formatted messages into clean HTML for email
- Prepare technical docs with code blocks and tables for a wiki or intranet
- Test Markdown compatibility across parsers (toggle GFM/breaks options)
- Turn a Markdown table into HTML for embedding in a report or spreadsheet
