The Markdown to HTML Converter transforms common Markdown syntax into escaped HTML and shows a live preview. It supports headings, paragraphs, emphasis, strong text, inline code, unordered and ordered lists, blockquotes, horizontal rules, and fenced code blocks.
Safety behavior
Text content is HTML-escaped before formatting is applied, so raw < and > characters are not inserted as executable markup. Links are converted only for http and https URLs.
Example
The Markdown:
## Heading
- One item
becomes a heading followed by an unordered list in the generated HTML.
Questions
Does it support every Markdown extension?
No. It implements the syntax listed above and is not a full CommonMark or GitHub-Flavored Markdown parser.
Are raw HTML tags preserved?
No. They are escaped as text for safer preview output.
Can I convert a file?
The current calculator accepts Markdown text. File upload and export are not part of this module.
Limitations
Tables, images, footnotes, task lists, nested structures, and many extensions are not implemented.
