Why Icons Must Be SVG for Modern Development

Raster icons look blurry on Retina displays and require multiple PNG sizes. SVG icons scale perfectly and are CSS-colorable from a single file.

  • One SVG replaces: 1×, 1.5×, 2×, 3× PNG icon exports
  • Perfect on 1080p, 4K, and Retina displays from the same file
  • CSS-colorable: change icon color with one CSS property
  • Typically 3–10× smaller file size than PNG 2× equivalent
  • Interactive: SVG paths can receive JavaScript events for rich UI interactions

Icon Vectorizer Settings for UI Development

Specific settings produce the cleanest SVG for UI icon use.

  • Icon preset: optimized for flat, simple graphics with clear edges
  • Low color count (1–4): monochrome or limited-palette UI icons
  • Remove background: ensure transparent PNG source
  • After conversion: run through SVGO for minimal file size
  • Check viewBox: ensure the viewBox is set to the icon grid (usually 24×24 or 16×16)

Frequently Asked Questions

What's the standard SVG icon size for web use?

24×24px viewBox is standard (Material Icons, Heroicons, Feather). 16×16 for compact icons. Set viewBox accordingly on the SVG element.

How do I make my icon SVG use CSS colors (currentColor)?

After converting, open the SVG in a text editor. Replace hardcoded fill values with fill='currentColor'. Then control the color via CSS using the color property.

Can I convert an entire icon set to SVG at once?

Pro accounts support batch upload. Free accounts convert 5 icons per day. For large icon sets (100+), use the Pro batch API.

What's the ideal source PNG size for icon vectorization?

128×128px minimum, 256×256px preferred for accurate curve fitting. Larger source icons produce SVG with more accurate paths.

How do I use my icon SVG in a React component?

Option 1: paste SVG markup directly in JSX. Option 2: use @svgr/webpack to import SVG as a component. Option 3: use an SVG sprite with <use> for large icon sets.
