Frequently Asked Questions

A single multi-resolution ICO holding 16×16, 32×32, 48×48 and 256×256 pixel versions. Windows chooses whichever suits the context, so the icon stays sharp in a taskbar, a folder listing and a large desktop tile.

Only with a decisive crop. At 16×16 there is room for about one recognisable shape, so a tight portrait or a single high-contrast object reads while a landscape does not. Crop first, convert second.

No. ICO entries are square, so a 3:2 EOS frame is fitted onto a square canvas. Crop to 1:1 yourself if you want to control what survives rather than leaving it to the conversion.

The format does — ICO stores 32-bit colour with an alpha channel. A CR3 supplies no transparency of its own, so the icon is opaque unless you remove the background before converting.
