About this tool
ICO files are multi-frame containers: a single .ico can bundle 16x16, 32x32, 48x48, and 256x256 versions of the same icon, each stored as either a BMP bitmap or an embedded PNG. The decode-ico library reads the binary header, walks every directory entry, and this tool automatically picks the largest frame for export. CUR cursor files use the same container layout and are handled identically. The extracted PNG preserves the full alpha channel, so transparent favicon backgrounds stay transparent in whatever editor you open next.
