Convert Markdown to HTML
Drop in a Markdown and get an HTML back. HTML is the file a web page is made of. The practical difference is that the result opens anywhere, which Markdown files do not. Your file never leaves your computer.

How to convert Markdown to HTML
- 1 Drop your Markdown .md or .markdown or .mdown file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to HTML, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the HTML, or add more files and do the whole set in one go.
Why convert Markdown to HTML
- A Markdown will not open in a browser, so anything going onto a web page, into a document or into a message has to become an HTML first.
- Renders in every browser with no plugin, viewer or conversion.
- Reflows to any screen size, which fixed-layout formats cannot do.
- HTML email templates rendered inside mail clients.
- Markdown: no control over layout, page breaks or typography.
Markdown compared with HTML
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | Markdown | HTML |
|---|---|---|
| File extension | .md | .html |
| Colour depth | UTF-8 plain text, parsed to an HTML document tree | UTF-8 markup rendered through the CSS box model |
| Browser support | No browser support | Every browser |
| Introduced | 2004 | 1993 |
| Developed by | John Gruber and Aaron Swartz | Tim Berners-Lee, now WHATWG |
Quality and what changes
Both sides are lossless, so every pixel survives the trip intact and converting back returns the same image. What changes is the size and what the file can carry: HTML stores the data without compression, so expect a much larger file.
- One HTML limitation to keep in mind: appearance depends on CSS, fonts and the browser, so it is not fixed layout.
Questions about Markdown to HTML
Is my Markdown file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your Markdown is read straight from your own disk, converted on your machine and handed back as an HTML. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several Markdown files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate HTML downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
