Markdown to HTML Converter
Convert Markdown to clean, sanitized HTML — free, private, in your browser.
✓ Your files never leave your device. Everything runs locally in your browser.
Markdown is the lingua franca of READMEs, documentation and notes. This converter turns Markdown into HTML you can paste into a website or CMS.
The output is sanitized with DOMPurify, which strips scripts and dangerous attributes — a safer default for untrusted content.
How it works
- Paste Markdown – Paste your Markdown into the input box.
- Convert – Click Convert to get HTML.
- Copy or download – Copy the HTML or download it as an .html file.
What is supported
- Headings, paragraphs and blockquotes.
- Bold, italic, inline code and fenced code blocks.
- Links, images, ordered and unordered lists.
Why sanitize?
If the Markdown comes from an untrusted source, it can contain raw HTML including scripts. Sanitizing removes anything dangerous; turn it off only for content you fully trust.
Frequently asked questions

Is raw HTML allowed in Markdown?
