What sizes are generated?

16×16, 32×32, 48×48 (bundled into favicon.ico), 180×180 (Apple Touch Icon), 192×192, and 512×512 (PWA icons).

Is transparency preserved?

Yes. The PNG alpha channel is preserved in all output files, including the ICO format.

What is the difference between favicon.ico and PNG icons?

favicon.ico bundles multiple sizes into one file for legacy browser support, while PNG icons are used by modern browsers and PWAs. Providing both ensures maximum compatibility.

What makes a good source image?

A square, transparent-background PNG at 512×512 pixels or larger gives the best results when scaled down to smaller icon sizes.

Favicon Tips & Use Cases

Website — Cross-Browser Compatibility

To display correctly in Chrome, Safari, Firefox, and Edge, provide both favicon.ico and PNG files. Upload all files in the generated ZIP to your web root and add the corresponding link tags to your HTML head.

PWA / Mobile Home Screen

For Progressive Web Apps and home screen shortcuts, you need 192×192 and 512×512 PNGs. Register both sizes in the icons array of your manifest.json to display high-resolution icons on Android and iOS.

Brand Identity — Logo as Icon

Crop just the symbol or mark from your logo into a square PNG before converting to a favicon. Keep the design simple — it should be recognizable even at 16×16 pixels.
