Question 1

Why can't I just paste SVG directly into JSX?

Accepted Answer

JSX looks like HTML but is JavaScript, and React has different attribute conventions: **`class` is reserved** (it's a JS keyword), use `className`. **`for` is reserved**, use `htmlFor`. **kebab-case attributes** like `stroke-width`, `stroke-linecap`, `fill-opacity`, `stop-color` need to be **camelCase** in JSX (`strokeWidth`, `strokeLinecap`, etc.), except for data/aria attributes which stay kebab-case. **`style="color: red"`** must become `style={{ color: 'red' }}` (object, not string). **`xmlns`**, **`xlink:href`**, **`xml:space`** need namespaced JSX equivalents (`xmlns`, `xlinkHref`, `xmlSpace`). Forget any of these and React either crashes or silently ignores the attribute, producing a broken icon.

Question 2

Should I make my icon accept color/size as props?

Accepted Answer

**Yes, almost always.** Hardcoded icons are limited to one usage. Best practice for reusable icon components: **(1) Accept `size`** (or width/height), letting consumers render 16px, 24px, 32px from one component. **(2) Use `fill="currentColor"` and/or `stroke="currentColor"`** so CSS color cascades into the icon, no `color` prop needed; consumers just set CSS `color` on the wrapper. **(3) Spread `...props` onto the SVG** so consumers can pass `onClick`, `aria-label`, `className`, `style`, etc. **(4) `forwardRef`** so refs work (useful for tooltip-positioning, focus management). Together, your icon library is themeable, sizable, accessible, and ref-able, for ~15 lines of code per icon.

Question 3

Should I generate components or use an SVGR/Webpack loader?

Accepted Answer

**For occasional one-offs**, this tool is faster, paste, copy, done. **For an icon system** (10+ icons), use **`@svgr/cli`** or its Webpack/Vite/Rollup plugins. Run once: SVG file in → React component out. Automatically updates on file change; consistent processing; integrates with build pipeline. SVGR also supports presets (TypeScript, native, etc.), prop forwarding, optional title prop for accessibility, and automatic SVGO optimization. **Use SVGR plugin** in Next.js / CRA / Vite to import SVG files as components: `import Icon from './icon.svg?react'`. The result is the same kind of component this tool generates, but automated and repeatable.

Question 4

How do I handle gradients with unique IDs in React components?

Accepted Answer

**The ID collision problem**: if your SVG has `<linearGradient id="grad1">` and you render the component twice on the same page, both share ID `grad1`, and per CSS rules, the first wins, so the second icon may render wrong. **Solutions**: (1) **Generate unique IDs per instance** using `useId()` (React 18+), `const id = useId(); ...id={`${id}-grad`}` and reference `fill={\`url(#${id}-grad)\`}`. (2) **Prefix IDs at build time** using SVGR's prefixIds plugin. (3) **Avoid gradients in icons**, flat fills are simpler. For UI icon systems, flat fills + `currentColor` covers 95% of needs; gradients are usually overkill for 16-24px icons.

Question 5

Why are some SVG attributes still kebab-case in JSX?

Accepted Answer

**Aria and data attributes** stay kebab-case: `aria-label`, `aria-hidden`, `data-testid`. These are HTML-level, not JSX-level, and React renders them as-is. **Namespaced SVG attributes** vary: `xlink:href` → `xlinkHref` in older React; React 17+ deprecated `xlink:*` in favor of plain `href` (the modern SVG spec). `xml:lang` → `xmlLang`. **Most kebab-case SVG attributes camelCase** (`stroke-width` → `strokeWidth`, `text-anchor` → `textAnchor`, `stop-color` → `stopColor`). The rule: HTML/aria/data stay kebab, SVG-specific (`stroke-*`, `text-*`, `fill-*`, `stop-*`, `font-*`) camelCase. This tool handles the mapping so you don't have to memorize it.

Question 6

Is my SVG sent anywhere when I convert it?

Accepted Answer

No. The conversion is regex + AST manipulation done in JavaScript locally, parse the SVG, rename attributes, wrap with component template, output. Open DevTools Network during use: zero outbound requests. SVG often contains brand logos, unreleased product icons, or proprietary illustrations; uploading them to convert would leak design IP. The tool processes locally so you can paste anything safely.

Question 7

What standards does SVG to JSX validate against?

Accepted Answer

SVG to JSX checks compliance with SVG 2 specification, React JSX specification.

Question 8

What are the limitations of SVG to JSX?

Accepted Answer

Does not convert all SVG attributes to React camelCase Inline styles may need manual adjustment Does not handle SVG <style> elements

SVG Attribute	JSX Key	Type	Notes
`class`	`className`	Reserved Key	Mandatory Mapping
`stroke-width`	`strokeWidth`	Kebab-to-Camel	SVG-specific
`aria-label`	`aria-label`	Literal	Aria-compliant
`fill-rule`	`fillRule`	Kebab-to-Camel	Path property
