Markdown to HTML Converter – Turn Markdown into Web Pages Free

Markdown is the easiest way to write structured text — headings with #, lists with dashes, emphasis with asterisks — but a browser cannot open a .md file as a web page. This free Markdown to HTML converter bridges that gap. Paste Markdown or drop a .md file and get a complete, standalone HTML page with a live preview, ready to download, open in any browser, email or publish. The download is a single self-contained file with its own basic styling, so it looks right anywhere. And it all happens locally in your browser: no uploads, no sign-up, and your drafts never leave your machine.

How to convert Markdown to HTML

Paste your Markdown into the box, or drag a .md, .markdown or .txt file onto the drop area and let the file fill the box for you. Press Convert to HTML. The page shows a live preview of the rendered result inside a sandboxed frame, so you can check headings, lists and links before committing. Then choose how to take it away: Download .html saves a complete standalone page — keeping the base name of a file you dropped, so notes.md becomes notes.html — and Copy HTML puts the same full document on your clipboard for pasting into an editor, a CMS or an email template. The counter under the preview shows the byte size in and out.

Your Markdown never leaves your device

Markdown files are where drafts live: unpublished posts, internal documentation, personal notes. Sending them to a conversion server means handing over work that may not be public yet, so this tool never does. The Marked library runs entirely in your browser; your text is read locally, converted locally and downloaded locally. Nothing is transmitted, stored or logged, and the preview is equally contained — it renders in a sandboxed iframe with no scripts allowed and no access to this page, so even Markdown containing raw HTML can only ever display inside that sealed box.

What the standalone page includes, and how Markdown maps to HTML

The download is not a bare fragment. It is a complete HTML document: a DOCTYPE and language, a head with a UTF-8 charset declaration so accented characters and emoji render correctly everywhere, a viewport tag for phones, the page title, and a small built-in stylesheet that gives the page comfortable margins, a readable serif body font, styled code blocks and responsive images. Inside, the mapping follows the usual rules: # headings become <h1> to <h6>, **bold** becomes <strong>, *italic* becomes <em>, links become <a href> with their destination kept, lists become <ul> or <ol> with nested items preserved, blockquotes become <blockquote>, tables become real <table> markup, and fenced code blocks become <pre><code> with their contents escaped — so code samples display as text instead of executing or breaking the page.

Limits and safety notes

Files up to 10 MB convert comfortably, far beyond any normal document. A few honest caveats. The styling is deliberately basic: it makes the page pleasant to read, but it is a starting point, not your site’s design — expect to restyle it for production. Markdown flavours differ, and this converter follows the common GitHub-style rules, so very exotic extensions from other dialects may render plainly. Most importantly, the downloaded file contains your rendered HTML exactly as converted, including any raw HTML you wrote in the Markdown itself: only publish or share it if that embedded HTML is yours and trusted, exactly as you would with any hand-written page. The sandboxed preview protects you while you work; the download is a faithful copy of your own content.
