Why convert PNG to ICO?
PNG is a lossless image format: every pixel is stored exactly, and it supports full transparency. It is the standard for screenshots, logos, icons and graphics with text.
ICO is the Windows icon format, also used for website favicons. One file can hold several sizes, such as 16, 32 and 48 pixels.
Choose ICO when you need a favicon for a website or an icon for a Windows program.
