How do I convert Markdown to HTML?

Upload your Markdown file using the box above, confirm HTML as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting MD to HTML free?

Yes, and there is nothing to sign up for. Every conversion route is free on every plan — paying raises limits such as file size and how many conversions you get, and removes advertising. It never unlocks a format, adds a watermark or degrades the output.

Will the quality change when converting to HTML?

HTML uses lossy compression, so some data is discarded to keep the file small. The default quality setting is tuned to be visually or audibly transparent for most material, and you can raise it in the conversion settings.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.

About MD and HTML

Markdown .md

Plain text with a light, readable convention for headings, links and emphasis. It stays legible as text while converting cleanly to formatted output.

Good for

Readable as-is, with or without a renderer
Diffs and version-controls well
Converts cleanly to HTML, PDF and word processor formats

Trade-offs

No fine layout control
Several competing dialects for tables and footnotes
Complex documents outgrow it

text/markdown

HTML .html

The markup language of the web: text wrapped in tags that describe structure, which a browser then renders.

Good for

Opens in any browser on any device
Structural and accessible when written properly
Styleable, linkable and searchable

Trade-offs

Appearance depends on the renderer and its stylesheet
Images and styles usually live outside the file
No fixed pagination — awkward to print predictably

What changes when you convert MD to HTML

Read as UTF-8

A MD is a text file, and a text file does not record which encoding it uses — that is the one thing the format cannot tell you about itself. We read it as UTF-8, which is right for essentially anything produced this decade. A file saved long ago in a regional encoding can arrive with accented characters mangled, and the fix is to re-save it as UTF-8 before converting rather than after. Tabs and spaces used to line columns up will also shift once the text is set in a proportional typeface.

The markup is sanitised

The HTML we produce is filtered down to a safe set of elements and attributes: scripts, event handlers and embedded objects are removed rather than carried through. This matters because converted files get opened in browsers, and a converter that faithfully preserved a script would be a way of passing one along. Structural markup, links, images and tables all survive.

Markers become real markup

The hashes, asterisks and brackets in Markdown are shorthand. This turns them into the elements they stand for — headings, emphasis, lists, links and code blocks — producing a document a browser understands structurally rather than as decorated text. What it does not add is styling: the output carries structure, and how it looks is for CSS to decide.
