What sizes are included?

Each .ico packs 16, 32, 48 and 64 px icons so browsers and Windows can choose the best fit.

Should my image be square?

Yes — icons are square, so a non-square image will be squashed. Crop it square first for best results.

What is an ICO file?

ICO is a container format that stores several icon sizes in one file. Browsers and Windows pick the right size for a favicon, taskbar, or shortcut automatically.

Why generate an ICO favicon?

A single favicon.ico with multiple resolutions renders crisply everywhere — browser tabs, bookmarks, and the desktop — without you shipping several separate PNGs.
