Markdown to HTML

The converter supports the full CommonMark specification including headings, bold, italic, links, images, ordered and unordered lists, blockquotes, code blocks (fenced and indented), horizontal rules, and tables. It also handles inline code, strikethrough, and nested formatting.

Yes — the converter produces properly nested, semantic HTML5 markup. Headings use h1-h6 tags, paragraphs use p tags, and lists use proper ul/ol/li nesting. The output is ready to paste into any HTML document or CMS without cleanup.

Yes — the converter supports GitHub-flavored Markdown (GFM) extensions including tables, task lists (checkboxes), strikethrough text, and fenced code blocks with language identifiers. These are the most commonly used extensions beyond standard Markdown.

The converter wraps fenced code blocks in pre and code tags with the appropriate language class (e.g., class="language-javascript"). Actual syntax highlighting requires a client-side library like Prism.js or highlight.js — the HTML output provides the correct markup for those libraries.

No — the Markdown parsing happens entirely in your browser using JavaScript. Your content never leaves your device. This makes it safe to convert private documentation, internal notes, or any sensitive content without privacy concerns.
