So, if you have enough reasons to convert JPG to ICO, simply pick an ICO converter from the list below.

Part 1. What is an ICO image?

Before jumping into the nitty-gritty of converting PNG or JPG to ICO, let's first discuss this file format. An ICO is a graphics file format used for computer icons in Windows systems. It has a .ico filename extension and can be used as a container for PNG and BMP. Having said that, an ICO file is commonly used in Windows operating systems to display icons for applications, shortcuts, directories, etc. In a typical scenario, the maximum pixel dimension for this format is 256p with a minimum of 16p. Therefore, anything larger or smaller will automatically be resized to these dimensions. You can open ICO files on Windows with programs like Microsoft Paint, Photos, Photoshop, and Fax Viewer.
