Convert Markdown to HTML Online Free
Turn a README or notes file into a web page in seconds. AllConvert converts Markdown to a complete HTML document, right in your browser. No upload, no account.
Why convert Markdown to HTML?
Markdown is wonderful to write but needs rendering to be read comfortably. Converting to HTML turns a README, meeting notes, documentation or a blog draft into a page that opens directly in any browser — ready to attach to an email, drop onto a web host, or hand to someone who has never heard of Markdown.
What does the output look like?
AllConvert produces a complete, standalone HTML document — not just a fragment. Headings, paragraphs, bold and italic text, inline code, fenced code blocks, links, images, ordered and unordered lists, blockquotes and horizontal rules are all rendered. Exotic extensions like tables, footnotes and task lists are not currently supported.
Going the other way
Have an HTML page you want as readable text instead? AllConvert also converts HTML to plain text, stripping the markup while keeping the content. And for data files rather than prose, see CSV to JSON.

Markdown was never designed to be a complete document. A .md file has no <head>, no charset declaration, no title tag — it's just marked-up text with no idea how a browser should render it. So the converter has to do two jobs, not one: parse the Markdown into an HTML fragment (the headings, paragraphs, code blocks and so on), then wrap that fragment in a real HTML5 document shell with a doctype, a UTF-8 meta tag, and a title pulled from your first heading. That's the difference between a snippet meant to be pasted into an existing page and a file you can double-click and have open correctly in a browser.
Frequently asked questions
Does the converter output a full HTML page or a fragment?
A complete standalone document with proper structure, so it opens directly in a browser and can be hosted or emailed as-is — not just a fragment you'd need to paste somewhere.
Which Markdown features are supported?
The common core: headings, bold, italic, inline code, fenced code blocks, links, images, lists, blockquotes and horizontal rules. Tables, footnotes and task lists aren't rendered.
Is my document uploaded anywhere?
No. The conversion runs entirely in your browser, so private notes and internal documentation never leave your device.
