Frequently asked questions
Why not just rename a PNG to .ico?
A real .ico file is a specific binary container that can hold several sizes at once, so the browser or OS picks the right one automatically. A renamed PNG only works in some contexts and looks blurry when scaled.
What if my image isn't square?
It'll be stretched to fit each square size — for best results, crop to a square first using Crop Image.
