Markdown to HTML Converter

1. Paste your Markdown — Drop or type Markdown into the editor. The preview updates instantly as you type — no "Convert" button to press.
2. Toggle between Preview and HTML Source — The Preview tab shows the rendered result (how it will look on a page). The HTML Source tab shows the raw <h1>, <p>, <ul> code you can copy into your site.
3. Tweak options — Toggle GFM extensions, single-line breaks, autolinking, syntax highlighting, and heading IDs in the Options panel.
4. Copy or download — Click Copy HTML to copy the source to your clipboard, or Download .html to save the file.

Markdown is the lingua franca of writing on the web. From GitHub README files to Notion docs, from Reddit comments to Substack drafts, it's everywhere — because it strips formatting down to its essential building blocks: a hash for a heading, asterisks for emphasis, a hyphen for a bullet. But sooner or later you need real HTML — for a WordPress import, a static-site build, an email template, or a custom CMS.

Our Markdown to HTML converter handles the translation cleanly, with full GitHub Flavored Markdown (GFM) support and a live preview that updates as you type:

• Complete CommonMark coverage — Headings (H1–H6), bold, italic, links, images, ordered and unordered lists, blockquotes, horizontal rules, inline code, code blocks, and paragraph breaks all render correctly.
• GFM extensions on by default — Pipe tables with cell alignment, task lists with disabled checkboxes (- [ ] and - [x]), strikethrough (~~text~~), fenced code blocks with language hints (```js ... ```), and bare URL autolinking.
• Syntax-highlighted code blocks — Code blocks with a language hint get color-coded keywords, strings, numbers, and comments. Built-in highlighters for JavaScript, Python, CSS, HTML, JSON, Bash, and SQL — and the HTML output uses semantic class names so you can re-style or extend in your own CSS.
• Live preview — The output updates as you type. No "Convert" button. See exactly how your Markdown renders before you copy.
• Preview vs HTML source toggle — Two tabs in the output: see the rendered HTML in the Preview view, or the raw HTML code (the actual tags you'll paste) in the HTML Source view. Copy and Download always grab the raw HTML.
• Heading anchors — H1 through H6 get auto-generated id attributes based on the heading text. Deep-link to any section with #my-section.
• Configurable single-line-break behavior — Standard Markdown treats a single newline as a space; enable the option for GitHub-comment-style behavior where every newline becomes a <br>.
• Safe by default — Raw HTML tags in your input are escaped, so pasting untrusted Markdown won't introduce XSS. You get clean, predictable output without surprises.

100% browser-based — your Markdown is never uploaded to any server. All parsing and rendering runs in your browser. No file size limits beyond your browser's available memory, no signup, no privacy concerns. Safe for unpublished drafts, internal docs, customer-facing copy, and anything else you wouldn't want passing through someone else's machine.

The tool supports drag-and-drop file upload, auto-saves your draft in localStorage, and works with .md, .markdown, .mdown, .mkd, and .txt files.

• Privacy-first architecture — Most online Markdown converters send your text to a remote server. Ours runs 100% in your browser. Your unpublished drafts, internal documentation, and proprietary content never leave your machine.
• Real GFM support, not just CommonMark — Many free converters claim "Markdown support" but choke on tables, task lists, or fenced code blocks with language hints. Ours handles every GFM construct correctly out of the box.
• Live preview — See your output instantly as you type. No "Convert" button, no waiting. The preview pane is exactly what your HTML will render to.
• Real syntax highlighting — Not just monospace styling. Code blocks with a language hint get color-coded tokens. The colors carry through to the exported HTML via semantic class names, so your final page looks just as polished.
• Safe HTML escaping by default — Many converters either let raw HTML through (XSS risk) or strip it noisily. Ours quietly escapes all HTML tags in your input — safe, predictable, no surprises.
• No ads, no signup, no tracking — Clean, distraction-free interface. Paste, edit, copy. No popups, no account requirements, no cookie banners.
• Draft persistence — Your last input is auto-saved in localStorage and restored when you return. Never lose work in progress.
• Configurable, not opinionated — GFM, single-line breaks, autolinking, syntax highlighting, heading IDs — you control what's on and off.

• Importing into WordPress / Ghost / CMS — You wrote your blog post in Markdown (because Markdown is faster than a WYSIWYG editor). Convert to HTML and paste into the HTML editor of your CMS.
• Building a static site — Generating HTML at build time from Markdown source files. Verify exactly how each post will render before you ship.
• Sending HTML emails — Draft your email content in Markdown, convert to HTML, then drop into your email template. Much faster than writing <p> tags by hand.
• Documentation portals — Quick check that a README or guide will render correctly before you push to GitHub or publish to a docs site.
• Notion / Obsidian → web — Export your notes as Markdown, convert to HTML, embed in a webpage. The export workflow that doesn't require a paid tier.
• Slack / Discord messages → blog — Salvage long-form content from chat threads (which are already Markdown-formatted) into a published article.
• Comparing Markdown flavors — Toggle GFM on and off to see how the same Markdown renders in CommonMark vs GitHub style. Useful for debugging cross-platform formatting issues.
• Teaching Markdown — Side-by-side Markdown source and HTML output is the fastest way to learn what each syntax produces.
• One-off page generation — Need a quick HTML page for an internal announcement, a landing draft, or a one-pager? Write it in Markdown, convert, wrap in a basic template, ship.
