Frequently asked questions
Which sizes should I include?
16, 32 and 48 pixels cover browser tabs and Windows. Add 256 for high-resolution Windows icons.
What if my image is not square?
It is centred on a transparent square canvas, so nothing is cropped or distorted.
Are my images uploaded?
No. This tool runs entirely in your browser, so your images never leave your device.
