What is PNG to ICO Converter?
PNG to ICO Converter turns PNG images into ICO icon files for favicons, Windows shortcuts, and application icons. PNG is a strong source format for icons because it supports transparency, and ICO can hold multiple sizes in one file. The tool decodes the PNG in the browser and packages the ICO output.
How does PNG to ICO Converter work?
This tool decodes the PNG source, renders standard icon sizes such as 16x16, 32x32, 48x48, and 256x256, then writes them into an ICO file. PNG alpha transparency is preserved for clean edges when the icon is displayed over different backgrounds.
