How to convert Markdown to HTML

  1. 1Paste your Markdown into the input panel, or upload a file.
  2. 2The HTML output updates as you type.
  3. 3Open the Preview tab to check how the content renders.
  4. 4Copy the result with the copy button.

Supported Markdown syntax

  • Headings, paragraphs, bold, italic, and inline code.
  • Links and images.
  • Bulleted, numbered, and nested lists.
  • Blockquotes and horizontal rules.
  • GitHub-flavored extras: tables, task lists, strikethrough, and fenced code blocks with a language.

Where to use the HTML

Paste the output into CMS fields and email templates that only accept HTML, or load it into a rich text editor that expects HTML content.

In a React app you can render saved HTML with the editorcn Static Renderer, which styles the content to match your shadcn/ui theme and can sanitize it for you.

A note on security

HTML that comes from users should be sanitized before you render it with dangerouslySetInnerHTML. Use a library like DOMPurify, or the sanitize prop on the Static Renderer, so links and attributes can't run scripts.

Convert Markdown to HTML in your own code

This tool is a headless Tiptap editor, so the same conversion takes a few lines in your app. See the Markdown extension docs for details.

convert.ts
import { Editor } from "@tiptap/core";
import { StarterKit } from "@tiptap/starter-kit";
import { Markdown } from "@tiptap/markdown";

const editor = new Editor({
  element: null,
  extensions: [StarterKit, Markdown],
});

editor.commands.setContent(markdown, { contentType: "markdown" });
const html = editor.getHTML();

Frequently asked questions

Does it support GitHub-flavored Markdown?

Yes. Tables, task lists, strikethrough, and fenced code blocks from GitHub-flavored Markdown are all converted.

Is my Markdown sent to a server?

No. Everything runs locally in your browser, so nothing you paste is sent to a server.

Is the HTML output clean?

The HTML is produced by a Tiptap editor schema, so it only contains well-formed, semantic tags. The only inline styles are column widths on tables.
