What does this tool do?
HTML to JSX converts raw HTML you paste into valid JSX you can drop straight into a React component. It saves time for developers migrating legacy templates, email snippets, or designer-supplied markup into a React project.
How to use it
- Paste or type your data into the left field.
- The result is generated instantly on the right.
- Use the Copy button to grab the output.
What it actually converts
The tool fixes the most common JSX incompatibilities in one pass: class becomes className, for becomes htmlFor, tabindex becomes tabIndex, and attributes like maxlength, colspan, cellpadding and crossorigin are camelCased. Inline style="margin: 0 auto" strings become style={{ margin: "0 auto" }} objects, void tags such as img, input and br are made self-closing, and HTML comments are rewritten as {/* ... */} JSX comments.
Typical use cases
It helps when porting a static Bootstrap or Tailwind landing page into React, turning a designer's HTML card into a component, or adapting a snippet copied from Stack Overflow. Copy the output and paste it directly into a .jsx or .tsx file. Because conversion happens as you type, you can paste large blocks piece by piece and see the result update instantly.
Frequently asked questions
How are inline styles handled?
Strings like style="margin: 0 auto; padding: 20px;" are parsed; each property is camelCased, and values that are non-numeric or end in px or % are quoted, producing a style={{ margin: "0 auto", padding: "20px" }} object.
Does it convert every HTML attribute?
It handles the most frequent ones (class, for, tabindex, readonly, autofocus, maxlength, colspan, rowspan, cellpadding, crossorigin, hreflang and similar). Rare or custom data-* attributes are already valid in JSX and are left untouched.
Can I use the output directly in React?
Yes, though the JSX must sit inside a component's return with a single root element or a Fragment. The tool fixes attribute and tag syntax; you add the root wrapper to match your project.
