Frequently Asked Questions

What is an ICO file?
ICO is a Windows icon container that bundles several pixel sizes of the same icon. The browser or OS picks the right size for each display context.
Which sizes should I include?
16 and 32 are required for favicons. Add 48 and 64 for sharper Windows desktop icons on hi-DPI screens.
Is the upload private?
There is no upload. The PNG is read locally and the ICO is assembled in your browser.
