Frequently Asked Questions
Why does HTML need to be converted to JSX in React?
JSX is a syntax extension for JavaScript, not raw HTML. Because JavaScript has reserved keywords, JSX requires different attribute names (such as className instead of class and htmlFor instead of for), camelCased attributes, self-closing void tags, and object-based inline styles.
How does this tool handle inline CSS styles?
The engine parses CSS style property strings and converts CSS hyphenated property names (like background-color and margin-top) into camelCased JavaScript object properties (like backgroundColor and marginTop), wrapping them in standard React double-brace syntax style={{ ... }}.
Does this converter work with SVG vector icons?
Yes! The converter handles all standard SVG attributes, converting hyphenated attributes like stroke-width, stroke-linecap, fill-rule, and clip-path into their valid React camelCased counterparts while preserving valid casing for viewBox.
Is my code sent to an external server?
No. 100% of HTML parsing and JSX generation happens locally within your web browser using client-side JavaScript. Your code, components, and proprietary designs never leave your browser memory.
