What is BMP to ICO Converter?
BMP to ICO Converter turns bitmap artwork into an ICO icon file. ICO stores several icon sizes in one container, which helps Windows and browsers choose the right size for each display context. The tool renders the BMP at standard icon dimensions and packages the result as an ICO file.
How does BMP to ICO Converter work?
This tool decodes the BMP file, draws it to browser canvas sizes such as 16x16, 32x32, 48x48, and 256x256, then writes those images into one ICO container. BMP sources are normally opaque, so the generated icon has a solid background. Use PNG input instead when the icon design needs transparency.
