ICO Converter online tools are websites that allow users to convert image files into ICO (icon) files. ICO files are commonly used for displaying small icons on a computer's desktop, taskbar, or in a website's favicon.
These online tools typically have a simple interface where users can upload an image file from their computer, and select the size and color depth of the resulting ICO file. Some tools may also allow users to crop or resize the image before conversion.
Some popular online tools for ICO conversion include ICO Convert, ConvertICO, and Online-Convert. These tools are free to use and do not require any installation or downloads.
