HTML to JSX Converter
Convert plain HTML markup to equivalent JSX: class to className, inline style strings to objects, void elements self-closed.
Tool guide
What this tool does
HTML to JSX Converter handles the common differences between HTML and JSX: class → className, for → htmlFor and other camelCased attributes, inline style="a:b;" strings → style={{a: 'b'}} objects, void elements (img, input, br) self-closed, and HTML comments → JSX comments.
Pasting plain HTML directly into a React component usually breaks on a handful of predictable differences, class instead of className, an inline style string instead of an object, an unclosed <img> tag, small but easy-to-miss details when converting by hand.
This tool handles those common differences automatically: renaming class/for/tabindex and other camelCased attributes, converting inline style strings to JSX style objects, self-closing void elements, and converting HTML comments to JSX comment syntax.
How to use HTML to JSX Converter
- Paste your plain HTML snippet.
- Review the generated JSX output.
- Copy the JSX into your React component.
- Manually review for any edge case this pattern-based conversion might have missed.
Tips for better results
- This is a text-based, pattern-matching conversion, not a full HTML parser, it handles typical hand-written markup well but may not perfectly handle every unusual edge case (deeply nested quotes within quotes, uncommon attribute syntax), always review the output before using it.
- data- and aria- attributes are left unchanged, since JSX (and React) use these exact same hyphenated names, unlike most other HTML attributes that need camelCasing.
- The inline style string conversion assumes simple property: value; pairs, separated by semicolons, more complex or malformed inline styles may not convert perfectly.
- Void elements (img, input, br, hr and others that never have closing tags in HTML) are automatically self-closed with a trailing slash, since JSX requires this for every element, unlike standard HTML.
Common use cases
- Converting a static HTML mockup or template into a starting React component.
- Porting markup copied from a design tool’s HTML export into a JSX codebase.
- Quickly fixing the class/for/style differences when adapting existing HTML for React.
- Learning the specific syntactic differences between HTML and JSX by comparing before/after.
Common mistakes to avoid
- Treating the output as guaranteed 100% correct JSX without reviewing it; this is a pattern-based text conversion, not a full parser, unusual markup may need a manual touch-up afterward.
- Expecting data- or aria- attributes to be renamed; they intentionally stay exactly as written, since JSX uses the same hyphenated attribute names for those specifically, unlike most other HTML attributes.
- Pasting a full HTML document (with <html>, <head>, <body> tags) expecting a usable React component, a React component typically represents a markup fragment, not an entire document structure.
Frequently asked questions
Does this handle every HTML attribute correctly?
It handles the most common ones that differ in JSX (class, for, tabindex, and similar), plus leaves data- and aria- attributes unchanged since those stay identical in JSX; less common attributes may need manual review.
Does this convert inline styles correctly?
Yes, for standard semicolon-separated property: value; pairs, it converts them to a JSX style={{ }} object with camelCased property names; unusual or malformed inline style syntax may not convert perfectly.
Are void elements like <img> and <br> handled?
Yes, they’re automatically self-closed with a trailing slash (e.g. <img /> instead of <img>), since JSX requires this for every element, unlike standard HTML, which allows unclosed void tags.
Is my HTML uploaded anywhere?
No, the conversion happens entirely in your browser using pattern matching; nothing is transmitted anywhere.
