Frequently Asked Questions
Which sizes should a Windows icon include?
16×16, 32×32, 48×48 and 256×256 cover Explorer, the taskbar and high-DPI displays. Adding 20, 24, 40 and 64 gives sharper results at 125% to 200% display scaling.
Is transparency supported?
Yes. The 32-bit alpha channel is preserved, so transparent and semi-transparent pixels look right on any background.
How is the ICO file built?
Sizes below 256×256 are stored as 32-bit bitmaps for maximum compatibility, and the 256×256 image is stored as compressed PNG, the same layout Windows uses for its own icons.
Can I use the ICO file as a favicon?
Yes, the resulting file works as favicon.ico. To get every icon a modern website needs, use the favicon generator instead.
