Why convert ICO to BMP?

People often ask why bother converting ICO at all. The short answer: BMP handles Uncompressed images on Windows noticeably better. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. This kind of format decision tends to matter more as a project scales up.
