About ICO Transparency

ICO is the standard icon format for Windows applications and favicons. ICO files can contain multiple image sizes (16x16, 32x32, 48x48, 256x256) in a single file, and each size supports transparency through alpha channels. This tool lets you remove background colors from ICO images and create transparent versions perfect for desktop icons and web favicons.
