Why convert ICO to BMP?
ICO is the Windows icon container, used for application icons and website favicons. It can hold one or more small images, typically 16x16 up to 256x256 pixels. BMP is an uncompressed raster format from early Windows. It preserves every pixel but produces very large files, so it is mainly used for compatibility with legacy software.
- BMP has no transparency channel, so any transparent areas are flattened onto a solid background (white by default, adjustable below).
- Improve compatibility — BMP is widely supported and easy to use across the apps and platforms you rely on.
