ICO vs SVG Favicon: When to Use Each

Modern websites use both: SVG favicon for modern browsers (scalable, dark mode), ICO for legacy browser fallback.

  • SVG favicon: Chrome, Firefox, Edge, Safari 15+ — scalable, supports dark mode
  • ICO favicon: IE, older Chrome, system taskbar — requires multiple pixel sizes
  • Best practice: serve both — <link rel='icon' type='image/svg+xml' href='/favicon.svg'> then <link rel='icon' href='/favicon.ico'>
  • ICO file contains: 16×16, 32×32, 48×48 PNG sizes in one file container
  • Windows application icons: ICO format required (256×256 included)

What's Inside an ICO File?

ICO is a container format that holds multiple image sizes.

  • 16×16: minimum browser tab favicon size
  • 32×32: taskbar and slightly larger browser favicon
  • 48×48: Windows shell icons
  • 64×64 or 128×128: higher DPI displays
  • 256×256: Windows Vista+ large icon view in Explorer

Frequently Asked Questions

Do I need an ICO favicon if I already have SVG?

Yes for maximum compatibility. Safari < 15, old Chrome versions, and IE require ICO. Always include both.

What's the best tool to convert SVG to ICO?

RealFaviconGenerator.net converts SVG to ICO with all standard sizes. Inkscape can export individual PNG sizes that you combine into ICO using icoconvert.com.

Should my ICO include PNG or BMP images internally?

Use PNG internally for ICO files — PNG compression produces much smaller ICO files. BMP-based ICO is a legacy format from before PNG was supported in ICO containers.

What size should my SVG be before converting to ICO?

SVG is resolution-independent — any viewBox size works. The ICO converter rasterizes at each required pixel size. A viewBox of 0 0 100 100 is typical for icon SVGs.

Can Windows application icons use SVG?

No — Windows requires ICO format for application icons. Convert SVG to ICO containing at minimum 16, 32, 48, and 256px PNG images.
