FAQ

Frequently asked questions

The converter supports standard CommonMark syntax: headings (H1–H6), bold, italic, bold+italic, code spans, fenced code blocks, unordered and ordered lists, blockquotes, horizontal rules, links, and images. With GitHub Flavored Markdown enabled it also supports tables, task lists (- [x]), and strikethrough (~~text~~).

No. All conversion runs entirely in your browser using JavaScript. Your content is never sent to any server and never leaves your device. This makes the tool safe for documentation drafts, internal notes, and confidential content.

When enabled, the output is wrapped in a complete HTML5 document skeleton with <!DOCTYPE html>, <html>, <head> (with UTF-8 charset and a title tag), and <body> tags. This produces a file you can open directly in a browser without any additional setup.

When you write a fenced code block with a language identifier (e.g. ```javascript), the converter adds a class="language-javascript" attribute to the <code> element. This follows the Prism.js and highlight.js convention, so you can drop in either library and get automatic syntax highlighting in your rendered page.

Yes. GitHub READMEs use GitHub Flavored Markdown (GFM). Enable the GFM option to get support for tables and task lists. The output is clean HTML you can embed in a webpage, documentation site, or email. Simply drag and drop your README.md file onto the upload zone.

Markdown to HTML Converter — Everything You Need to Know

Markdown is the go-to format for developers writing documentation, README files, blog posts, and notes. But most websites and applications ultimately need HTML. Our free Markdown to HTML converter bridges that gap instantly, with no login required and nothing uploaded to any server.

Why convert Markdown to HTML?

Markdown is designed for human readability, but browsers render HTML. Converting Markdown to HTML lets you publish content to static sites, embed formatted text in web apps, send rich emails, or integrate documentation into a CMS. It is also useful for previewing how Markdown will look when rendered — the live preview tab shows the exact result.

GitHub Flavored Markdown (GFM) support

Standard Markdown doesn't support tables, task lists, or strikethrough text — but GitHub Flavored Markdown does. Enable the GFM option in our converter to support all three. Tables use pipe syntax and are converted to semantic <table>, <thead>, and <tbody> elements. Task list items become checkboxes. Strikethrough (using ~~double tildes~~) becomes <del> tags.

Code blocks and syntax highlighting

Fenced code blocks (wrapped in triple backticks) are converted to <pre><code> elements. When you specify a language (e.g. ```python), the converter adds a class="language-python" attribute, making it compatible with Prism.js and highlight.js for syntax coloring. Code inside blocks is HTML-escaped so angle brackets and ampersands are safe.

Using the converted HTML

Once converted, copy the HTML and paste it into your CMS, static site generator, or email template. If you enabled "Wrap in HTML document," the output is a complete, self-contained HTML file you can open in any browser immediately. Download it with one click and rename it as needed.

Markdown to HTML vs. Markdown renderers

Libraries like marked.js, Showdown, and Python-Markdown convert Markdown to HTML programmatically. Our tool is a quick online alternative for one-off conversions — no npm install, no Python environment, no configuration. For production pipelines with thousands of documents, a programmatic library makes more sense; for quick conversions, this tool gets you there in seconds.
