Markdown to HTML

This Markdown to HTML converter turns your Markdown text into clean HTML the moment you type it. Paste or edit Markdown in the left panel and the tool builds the matching HTML on the right, where you can flip between the raw HTML source and a rendered preview. Everything runs in your browser, and one click copies the HTML to your clipboard.

Why use Markdown to HTML?

The Markdown to HTML tool takes Markdown text on the left and produces HTML on the right in real time. As you type in the Markdown Input box, the converter rewrites your syntax into tags: hash headings become h1 through h3, double asterisks become strong, single asterisks become em, backticks become inline code, and bracket-parenthesis link and image patterns become anchor and img elements. It also converts greater-than lines into blockquotes, three dashes into a horizontal rule, and blank lines into line breaks. The input starts with a small sample so you can see the behavior immediately and then replace it with your own text. Output is presented two ways. The html tab shows the raw markup the tool generated, which is what the Copy HTML button places on your clipboard. The preview tab renders that same markup inline, so you can check how the headings, emphasis, links, and quotes actually look before you use them. Because the two views share one output, what you see in preview is exactly what you copy from the html view. This is a focused, single-input converter rather than a full CommonMark engine. It works well for quick drafts, README-style snippets, and short posts, but it does not process tables, bullet or numbered lists, or fenced code blocks, so keep that in mind for longer documents. There is no file upload and no batch mode; you work with one block of text at a time. Since all processing happens locally in the browser through simple text substitution, nothing you paste is sent to a server, which makes it convenient for quick, private conversions.

Frequently asked questions

Which Markdown syntax does this converter support?

It handles headings (#, ##, ###), bold (**text**), italic (*text*), inline code (`code`), links [text](url), images ![alt](src), blockquotes (> line), horizontal rules (---), and blank lines that become line breaks.

Does it support tables, bullet lists, or fenced code blocks?

No. This is a lightweight converter for the common inline and block elements listed above. Multi-line lists, tables, and triple-backtick code fences are not part of its conversion rules.

Do I need to click a button to convert?

No. The HTML regenerates automatically every time you edit the Markdown Input box, so the output always matches your current text.

How do I get the HTML out of the tool?

Open the html tab and click the Copy HTML button. That copies the full generated markup to your clipboard so you can paste it wherever you need it.

Is my Markdown uploaded anywhere?

No. The conversion runs entirely in your browser using local text processing, so your content never leaves your device.

What is the difference between the html and preview tabs?

The html tab shows the raw HTML source that the tool produced, while the preview tab renders that HTML so you can see the visual result.
