How it works
Add your Markdown
Drop a .md file or paste Markdown text into the editor — the preview renders it instantly.

Copy the HTML to your clipboard for a CMS, or download a .html file ready to open or publish.
About the formats
Markdown — Markdown
Markdown is a plain-text format that marks structure with simple punctuation — # for headings, ** for bold, - for lists. It has become the native output format of the AI era: ChatGPT, Claude, Copilot and coding agents all write Markdown, GitHub renders it, and note apps like Obsidian store everything in it. A .md file is just text, which is why it opens in any editor but looks unformatted without a renderer like this one.
HTML — HyperText Markup Language
HTML is the markup language of the web: every page you read in a browser is HTML. It expresses the same structures as Markdown — headings, lists, tables, links, code — with more verbose tags, which is why the two convert into each other so cleanly. Converting HTML to Markdown strips the boilerplate and keeps the content; converting Markdown to HTML makes it publishable anywhere.
Frequently asked questions
Is this safe? Do my files get uploaded?
No upload happens — ever. Converting Markdown to HTML runs entirely inside your browser. Your documents never leave your device, nothing is stored on any server, and the tool keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Do I get a full HTML page or just a fragment?
Your choice. Standalone mode produces a complete, self-contained .html file with embedded styles — open it in any browser and it looks like a rendered document. Fragment mode outputs just the content markup (h1, p, table…) with no wrapper, ready to paste into a CMS, a blog engine or an email template.
Is GitHub-flavored Markdown supported?
Yes — tables, task lists, strikethrough, autolinks and fenced code blocks all convert. Code blocks are syntax-highlighted at conversion time with static markup, so the output needs no JavaScript libraries to look right.
Is the generated HTML safe to publish?
The converter sanitizes the output: script tags, event handlers and other active content are stripped, so a Markdown file from an untrusted source can't smuggle JavaScript into your page. What comes out is plain structural markup.

Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here the work happens on your machine, so the only practical limit is your device's memory. Even book-length documents convert in seconds — text is light work for a modern browser.
