🔁 Convert BMP to ICO
About these formats
About BMP. BMP is an old, essentially uncompressed bitmap format. Files are very large for what they contain, so converting to a compressed format saves a lot of space with no visible difference.
About ICO. ICO is the multi-resolution icon container browsers load as a site favicon. A single .ico bundles several sizes so the browser can pick the sharpest one.
Your BMP image is rendered at several small sizes and packed into a single ICO file, ready to serve as a website favicon.
When to keep the original instead. There is no quality penalty to worry about here, but it is still wise to keep the original BMP as a master copy.
