ICO to BMP Converter

Pulling an icon out of an ICO file for an old Windows tool that reads BMP is the niche but real reason for this pair. ICO is a container format for icons that can hold several sizes of the same picture in one file, used for favicons and app icons. This free ico to bmp converter does that conversion entirely in your browser, so your file is never uploaded and no signup is needed. BMP output is an uncompressed 24-bit bitmap, which any legacy tool can open, at the cost of a much larger file than the input. The honest limits: BMP has no transparency in this 24-bit output, so see-through areas become white. The file will also be much larger than the input.
