Markdown to HTML Online

What is Markdown to HTML?

Use this Markdown to HTML converter to turn CommonMark and GitHub Flavored Markdown into HTML elements: headings, links, lists, fenced code, and tables. Paste a note, README, or draft and copy the HTML. Conversion runs in your browser.

Introduction

The left editor is Markdown. The right editor is the HTML source, updated as you type. Nothing is uploaded. Use it when a CMS, email template, or blog field wants HTML instead of Markdown.

Key features

1. Markdown to HTML for headings, links, lists, code fences, and GFM tables
2. Check the tags before you publish
3. The other direction: when you already have HTML, use HTML to Markdown
4. Wider tables: shape them in the Markdown table tool, then convert

Tips

1. The result is HTML source, not a rendered page preview
2. Raw HTML in the Markdown is kept, following CommonMark. Paste only content you trust
3. A table sample inside a code fence stays code
4. To fetch a page and produce Markdown, use HTML to Markdown. For many URLs, use batch URL to Markdown

FAQ (essentials)

Is my Markdown uploaded?

No. Parsing stays in the browser. The text is not sent to the devtool.tech server.

How is this different from HTML to Markdown?

This page is Markdown → HTML. HTML to Markdown is the inverse and can also fetch a public URL.

How to use

Paste Markdown

Paste Markdown into the left editor. Common block and inline syntax follows CommonMark. Pipe tables follow the GFM tables extension.

Read the HTML

The read-only pane shows HTML source: h1–h6, a, ul/ol, pre/code, and table. Element behavior is documented on MDN.

Copy the result

Use Copy Markdown and Copy HTML at the bottom of the tool. Reset restores the sample.

What is covered

• Headings, emphasis, links, and inline code
• Ordered and unordered lists
• Fenced code blocks, including a language tag
• Pipe tables, with colons for alignment
• A | sample inside a code fence is not parsed as a table

Footnotes, math, and custom containers are out of scope. To turn HTML back into Markdown, use HTML to Markdown.

FAQ

What is Markdown to HTML?

It maps Markdown source to HTML tags using CommonMark and GitHub Flavored Markdown, so you can paste the result into an editor or template that expects HTML.

Is my content uploaded to a server?

No. Conversion runs locally in the browser. Neither the Markdown nor the HTML is uploaded to devtool.tech.

How is this different from HTML to Markdown?

This tool is Markdown → HTML. HTML to Markdown is the other direction, and it can also fetch a public URL before converting.

Which syntax is supported?

Headings, links, emphasis, lists, inline code, fenced code blocks, and GFM tables. A delimiter row uses hyphens, and colons set alignment, as described in the GFM tables extension. Merged cells need real HTML; see the MDN table element.

Why does a table inside a code block stay as text?

Fenced code is literal. The pipes are not parsed again. That matches CommonMark fenced code blocks.

Can I publish the HTML on a blog?

Most editors accept these basic tags. Check that links are absolute, and that the platform does not strip table or pre.
