About Markdown to HTML Converter

The Markdown to HTML Converter transforms Markdown text into clean, standards-compliant HTML instantly in your browser - no server, no API, no dependencies. It supports the full CommonMark-style Markdown spec including headings, bold, italic, strikethrough, inline code, fenced code blocks, blockquotes, ordered and unordered lists with nesting, tables, horizontal rules, links, and images.

Type or paste your Markdown into the left panel and the rendered HTML preview updates live in the right panel. Toggle to the HTML source view to inspect the raw generated markup. When you are happy with the output, copy the HTML snippet with one click or download a complete self-contained HTML file with a built-in stylesheet ready to open in any browser.

This tool is useful for a wide range of workflows: converting README files to HTML for documentation sites, transforming blog drafts written in Markdown into publishable HTML, generating email body content from Markdown, producing HTML snippets for CMS platforms that accept raw HTML input, and previewing how Markdown will render before committing it to a repository.

All user-provided text is HTML-escaped before insertion into the generated markup, preventing cross-site scripting. Links are validated to ensure only safe protocols (http, https, relative paths, and anchor fragments) are rendered as clickable anchors - any attempt to insert javascript: or data: URIs produces plain text instead. Image sources are similarly validated to allow only http, https, and data:image/ URIs.

The downloaded HTML file includes a clean inline stylesheet with sensible typography, table styling, code block formatting, and blockquote styling - suitable for sending as a standalone document or importing into a CMS.
