  • Create .ico with transparency: Natively supports the alpha channel from your PNG files, ensuring your icon looks great on any background. This is essential for a clean, professional look.
  • Multi-Size ICO Generation: Don't settle for a single-size icon. Our multi-size ico generator bundles all necessary resolutions (16x16, 32x32, 48x48) into one file, guaranteeing a crisp icon on both standard and HiDPI displays.
  • Beyond the Browser: Use our tool to make a 16x16 icon for your browser tabs, but also generate the larger sizes needed for Windows shortcuts and other contexts.

PNG to favicon (.ico)

Convert PNG to favicon (.ico) in seconds — fully client‑side, with multiple sizes packed in one ICO for crisp results on tabs, bookmarks and taskbars.

Why ICO still matters

ICO is the most compatible favicon format. It can bundle multiple bitmap sizes (16–256) inside a single file, so Windows/legacy contexts and various browsers always find a crisp variant. Modern setups keep both: an ICO for universal compatibility and an SVG (mask icon) for modern UIs.

Recommended sizes (by scenario)

  • Classic tabs: 16×16, 32×32
  • Hi‑DPI desktop: 48×48, 64×64
  • Windows/large contexts: 128×128, 256×256
  • Apple Touch (PNG): 180×180 (outside the ICO)
  • Mask icon (SVG): for Safari pinned tab

<link rel="icon" href="/favicon.ico" sizes="any">
<link rel="icon" href="/favicon.svg" type="image/svg+xml">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">
<link rel="mask-icon" href="/safari-pinned-tab.svg" color="#0f172a">
<meta name="theme-color" content="#0A0F1E">

Troubleshooting

  • Blurry at 16px: simplify the mark, increase contrast, retry with “sharp small icons”.
  • Wrong background: keep transparent PNG or explicitly set a solid color.
  • Browser shows old icon: hard refresh or add a cache‑buster (e.g. ?v=2).

SEO & performance tips

  • Keep ICO small by avoiding unnecessary large sizes if you don’t use them.
  • Add Apple Touch PNG and mask icon SVG for best coverage.
  • Reserve space for dynamic UI and ads to avoid CLS (already handled here).

FAQ

Why include multiple sizes?

Browsers and platforms pick the best size automatically, improving sharpness.

Can I use the ICO as my site favicon?

Yes. Link the ICO in the head and keep an SVG alternate for modern browsers.
