Both ICO and BMP preserve image quality without loss. The conversion between these formats is about broader compatibility.
ICO (Icon File Format, introduced in 1985) uses None (BMP payload) or PNG payload compression. BMP (Bitmap Image File, introduced in 1986) uses None (RLE optional but rarely used) compression. ICO supports transparency, but BMP does not. Transparent areas will be filled with a solid background color (typically white) during conversion. ICO browser support: Universal. BMP browser support: All modern browsers.
Both ICO and BMP use lossless compression. The conversion preserves 100% of the original data — the output file is pixel-for-pixel (or sample-for-sample) identical to the input. No quality is lost during this conversion.
Typical ICO file size: A multi-size favicon (16+32+48+256): ~15-100 KB. Typical BMP file size: A 12MP photo: ~36 MB (24-bit uncompressed).
Before converting, choose your background color carefully. BMP does not support transparency, so transparent areas will be filled with a solid color. White is the default, but a specific brand color may work better for your use case.
