What is the difference between GitHub Flavored Markdown and standard Markdown?
Standard Markdown (CommonMark) covers the everyday syntax: headings, bold and italic, links, images, lists, blockquotes, inline code, and fenced code blocks. GitHub Flavored Markdown (GFM) is a superset that adds three things many writers expect: tables built with pipes and dashes, ~~strikethrough~~ that renders as a <del> tag, and task lists where - [x] and - [ ] become checkboxes. Plain Markdown ignores those extras and leaves them as literal text, so a table would show up as raw pipe characters. This converter parses CommonMark by default and lets you toggle GFM mode on with a single checkbox when your source uses tables, strikethrough, or checklists. Paste your Markdown above and switch GFM on if your output is missing tables or checkboxes.
How does the Sanitize HTML option keep the output safe to paste into a page?
Markdown lets you mix raw HTML directly into your text, which means a pasted snippet could carry active or unwanted code. The Sanitize HTML option, on by default, strips that risk before you ever copy the result. It removes dangerous tags entirely -- <script>, <style>, <iframe>, <object>, <embed>, and form elements -- along with inline event handlers like onclick and any javascript: URLs hidden in links. What remains is clean, semantic markup you can drop straight into a CMS, email template, or live page without smuggling in executable code. If you specifically need to preserve embeds or scripts from a trusted source, you can turn sanitization off. For most publishing workflows, leave it on, then convert your Markdown above and copy the safe HTML.
Why do the headings in my converted HTML have id attributes?
Every heading the converter produces -- from <h1> down to <h6> -- gets an automatically generated id slug derived from the heading text. A heading like "Getting Started" becomes id="getting-started", lowercased with spaces turned into hyphens. These ids exist so you can deep-link directly to a section using a URL fragment, such as page.html#getting-started, and so a table of contents can jump readers to the right spot. It is the same anchor behavior you see on GitHub READMEs and documentation sites. You do not have to write the ids yourself; they appear in the Raw and Minified output ready to use. Paste your Markdown above, switch to the Raw tab, and you will see each heading already carrying its anchor id.
What does the Minified tab do and when should I use it?
The Minified tab shows the exact same HTML as the Raw output but with line breaks and redundant whitespace stripped out, and it reports how many characters smaller the result became. Minified markup behaves identically in a browser; it just takes up fewer bytes because the spacing that makes source readable is removed. That matters in places where size or formatting is sensitive -- pasting markup into an email template, embedding HTML inside a JSON field, or dropping a fragment into a CMS box that mangles indentation. For editing and inspecting your tags, use the Raw view; when you are ready to ship and want the leanest output, copy from Minified. Convert your Markdown above, then compare the Raw and Minified character counts to see the saving.
How do I get syntax highlighting to work on my converted code blocks?
When you write a fenced code block, add a language hint right after the opening backticks, like ```js or ```python. The converter turns that block into <pre><code> and attaches a matching CSS class -- language-js, language-python, and so on -- to the <code> element. That class is exactly what client-side highlighters such as Prism.js and highlight.js look for to colorize the code on your page. The converter itself does not paint colors in the Raw output; it produces the standard, highlighter-ready markup, and you load Prism or highlight.js on the destination page to do the actual coloring. A code block with no language hint still converts correctly, just without a language class. Paste your fenced code above with a language label and check the Raw tab for the language class.

About the Markdown to HTML Converter
The Markdown to HTML Converter turns Markdown into clean, semantic HTML the instant you type it. Paste a README, a blog draft, release notes, or documentation on the left and the rendered HTML appears on the right in three views: a live Preview, the Raw source you can copy, and a Minified version stripped of whitespace. It is built for developers, technical writers, and content teams who write in Markdown but need to paste real HTML into a CMS, an email template, a static site, or anywhere a Markdown editor is not available.
Everything runs in your browser. The Markdown is parsed locally with JavaScript, so nothing you paste is uploaded, logged, or stored on a server — useful when the source is an unpublished post, internal docs, or a private repository's README. There is no sign-up, no usage cap, and nothing to install.
What Markdown gets converted
The parser supports the common Markdown syntax you write every day and emits standards-compliant HTML5 tags:
- Headings —
#through######become<h1>–<h6>, each with an auto-generatedidslug so you can deep-link to a section. - Text styling — bold, italic, combined bold-italic, and inline
code. - Code blocks — fenced blocks render as
<pre><code>, and a language hint like```jsadds alanguage-jsclass for syntax highlighters such as Prism or highlight.js. - Lists — ordered (
<ol>) and unordered (<ul>), plus blockquotes, horizontal rules, links, and images.
Turn on GFM mode (GitHub Flavored Markdown) to also get tables, ~~strikethrough~~ as <del>, and task lists — - [x] and - [ ] render as disabled checkboxes, the same way GitHub displays them.
Sanitization and the full HTML5 document option
Two checkboxes change the shape of the output. Sanitize HTML, on by default, strips anything unsafe from the result: <script>, <style>, <iframe>, <object>, <embed>, and form elements are removed, along with inline on* event handlers and javascript: URLs. That matters because Markdown allows raw HTML, so a pasted snippet could otherwise smuggle in active code — sanitizing makes the output safe to drop straight into a page.
Full HTML5 document wraps the body in a complete page: a <!DOCTYPE html> declaration, a <head> with UTF-8 charset and a responsive viewport meta tag, and a <body>. Leave it off to get just the content fragment for pasting into an existing template; turn it on when you want a standalone file. Either way, Download .html saves the result as a ready-to-open file.
Why convert Markdown to HTML
Markdown is fast to write and easy to read, but browsers, email clients, and most publishing systems ultimately render HTML. A reliable converter bridges that gap without a build step or a full static-site generator. Typical uses include:
- Pasting a polished article into a CMS or newsletter that accepts HTML but not Markdown.
- Generating the body for a landing page or documentation page from notes you already wrote in Markdown.
- Inspecting exactly which tags your Markdown produces before shipping it.
The Minified tab shows the same HTML with line breaks and redundant whitespace removed, and reports how much smaller the result is — handy when you are pasting markup into an email or embedding it where every byte counts. Live character and line counts on both the input and output panes let you keep an eye on size as you edit.
To start, paste your Markdown above or load the built-in sample, toggle GFM, sanitization, and the document wrapper to taste, then copy the HTML or download it as a file.
