Four Ways to Embed SVG Icons

Choose the SVG embedding method based on whether you need CSS styling, animation, or just display.

  • Inline SVG: paste SVG code directly in HTML — best for styling with CSS and animation
  • <img src='icon.svg'>: simple display, no CSS color control from outside
  • CSS background: background-image: url('icon.svg') — for decorative icons only
  • SVG sprite: one SVG file with all icons, referenced with <use href='sprite.svg#icon-id'>
  • React/Vue: import SVG as a component for the best DX in modern frameworks

Inline SVG — Most Flexible Method

Inline SVG allows CSS to control fill color, size, hover states, and animations directly.

  • Paste SVG code into HTML: <svg viewBox='0 0 24 24'><path .../></svg>
  • Control color: svg { fill: currentColor } — inherits text color
  • Size with CSS: svg { width: 1.5em; height: 1.5em; }
  • Hover effect: svg:hover { fill: #ff0000; }
  • Downside: inline SVG bloats HTML — use sprites for repeated icons

Frequently Asked Questions

Which SVG icon method is best for performance?

SVG sprites are the best for performance — one HTTP request for all icons, cached by the browser, and reused with <use>. Inline SVG is fine for 1–5 icons per page.

Why doesn't CSS color work on my SVG icon?

The SVG paths have a hardcoded fill='#000000' attribute. Remove or change it to fill='currentColor' in the SVG code. Then CSS color: red on the parent element will color the icon.

How do I convert imagetosvg.com output to a website icon?

Download the SVG, open in Inkscape, simplify paths, remove any background rectangle, set fill to currentColor if needed, then embed inline or as <img>.

What's the best icon size for SVG on web?

Design SVG icons on a 24×24 or 16×16 grid with the viewBox set to 0 0 24 24. Scale with CSS width/height. Never hardcode px size in the SVG — let CSS control the display size.
