Converting Between Markdown and HTML
What this converter does
Markdown is a plain-text writing format; HTML is the markup a browser actually renders. This tool moves content between the two in both directions. Paste Markdown and you get HTML with the styling already baked in; paste HTML and the tool walks the tags back down to clean Markdown. A built-in parser handles the whole job, so you can convert a README, an article draft, or a snippet of documentation without wiring up a build step or installing a library.
When to use it
It earns its place when Markdown notes need to land somewhere that only speaks HTML — a CMS field, an email template, a page section — and you would rather not hand-write the tags. The reverse direction helps when you inherit HTML and want to keep editing it as Markdown. Four themes (GitHub, Minimal, Classic, Modern) let you preview roughly how the result will look and pick a tone before you copy it out. A live preview and a raw-code view sit side by side so you can check both the rendering and the exact markup.
A concrete example
Type `# Release Notes` and the converter emits an `<h1>` heading. A word wrapped in double asterisks, `**shipped**`, becomes `<strong>shipped</strong>`; a block opened with three backticks turns into a `<pre><code>` pair with the language recorded as a class. Lists, links written as `[label](url)`, images, blockquotes, and `---` horizontal rules all map to their HTML equivalents. Convert the other way and each `<h1>` drops back to `#` and each `<strong>` back to `**`, so the structure survives the round trip.
Notes and edge cases
The parser covers the everyday Markdown you write by hand — headings, emphasis, inline and fenced code, links, images, lists, blockquotes, and rules — rather than every extension. Markdown tables are not parsed, so a pipe table stays as literal text; if you need one, write it directly in HTML. Styling is applied as inline `style` attributes on each element instead of a separate stylesheet, which is what makes the output safe to drop into an email or a CMS box that strips `<style>` blocks. Each theme also generates light and dark variants automatically to match the page.
