Frequently Asked Questions

What is an ICO file?

ICO is the icon file format used by Windows and web browsers for favicons. A single ICO file can contain multiple image sizes, so the system picks the best one for each context.

Which sizes should I include?

For website favicons, 16x16, 32x32, and 48x48 cover most use cases. Add 64x64 or 128x128 for high-DPI displays. 256x256 is used by Windows for large icon views.

Will my image be cropped to a square?

Yes, the image is resized to fit each selected square dimension. For best results, start with a square image or crop it first using our crop tool.
