Markdown to HTML Converter – Free Online Tool

Introduction

The Markdown to HTML Converter turns Markdown text into clean, ready-to-use HTML in seconds. Writers, bloggers, and developers use Markdown for its simplicity — but websites, email templates, and CMS editors need HTML. Paste your Markdown into this free online converter and get sanitized HTML with a live preview, ready to copy or download. No signup required, and everything runs privately in your browser.

How to Use

1. Paste or type your Markdown into the box.
2. Choose HTML fragment for embedding into an existing page, or Complete HTML page for a standalone file.
3. Tick Convert single line breaks to <br> (on by default) if you want single line breaks to become <br> tags.
4. Click Convert to HTML to see the live preview and generated code.
5. Copy the HTML to your clipboard or download it as a .html file.

Frequently Asked Questions

What is Markdown?

Markdown is a lightweight plain-text formatting syntax. Writers use simple characters like # for headings and ** for bold, which converters then turn into proper HTML.

Is the generated HTML safe to use?

Yes. The output is automatically sanitized — potentially dangerous tags and inline scripts are removed before the HTML is shown or downloaded.

What is the difference between a fragment and a complete page?

An HTML fragment is just the converted content, ready to paste into an existing web page or CMS. A complete HTML page wraps it in a full document you can open directly in any browser.

Does it support tables and code blocks?

Yes — GitHub-flavored Markdown is supported, including tables, fenced code blocks, task lists, and strikethrough.

Is my text uploaded anywhere?

No. The Markdown to HTML Converter runs entirely in your browser. Your text never leaves your device.

What filename does the downloaded file use?

The file downloads as markdown-converted_trencada.html — a plain .html file you can open in any browser or edit in any text editor.

Do single line breaks become <br> tags?

Yes, by default. Keep the Convert single line breaks to <br> option checked and each single line break becomes a <br> tag. Uncheck it if you prefer strict Markdown, where only blank lines start new paragraphs.
