Which Markdown features are supported?

The converter supports the core CommonMark subset used by 99% of writers: ATX headings (# to ######), paragraphs, bold (**text**) and italic (*text*) emphasis, inline code with backticks, fenced code blocks with ``` and language hints, ordered and unordered lists with nesting, blockquotes, horizontal rules, links, images, and hard line breaks.

Does the output sanitize HTML injected in the Markdown?

Yes. All text content is HTML-escaped before being emitted, so characters like , and & become <, >, and &. The converter does not pass through raw HTML tags written inside the Markdown — they are rendered as literal text, which is safer for user-supplied content.

How is this different from a GitHub-flavored Markdown renderer?

This tool targets standard CommonMark. GitHub extensions like task lists, tables, autolinked URLs, and strikethrough are not currently supported. For most documentation, README, and blog use cases the CommonMark subset is enough. If you need GFM, tools like markdown-it with the gfm plugin add those features.

Is this tool free to use?

Yes. The converter runs entirely in your browser with no account required. Your Markdown never leaves your device.

Does this work on mobile?

Yes. The tool is fully responsive and works on any device with a modern browser.
