How to use Markdown ↔ HTML Converter

  1. 1

    Open the Markdown ↔ HTML Converter

    Go to tools.slaytic.com and open the tool. No sign-up or account required.

  2. 2

    Pick a direction and paste your content

    Choose Markdown → HTML or HTML → Markdown, then paste in your content.

  3. 3

    Copy or download the result

    The conversion updates automatically as you type. Copy it to your clipboard or download it as a file.

How this works in your browser

This tool uses a small hand-written Markdown parser for the Markdown → HTML direction, and your browser’s native DOMParser for HTML → Markdown, no external Markdown library. Conversion is debounced slightly so a long document does not re-parse on every keystroke while you are still typing.

Frequently asked questions

Is this Markdown/HTML converter free?

Yes, completely free with no limit on how much content you convert.

What Markdown syntax is supported?

Headings, bold, italic, links, images, ordered and unordered lists, code blocks, inline code, and blockquotes.

Will converting HTML back to Markdown be a perfect round trip?

For common formatting it converts cleanly. Complex or unusual HTML (tables, embedded scripts, custom attributes) may not have a clean Markdown equivalent.

Does it convert as I type, or do I need to click a button?

It converts automatically a moment after you stop typing. A Convert button is also there if you want to trigger it immediately.

Is my content sent anywhere?

No, the conversion runs entirely in your browser.
