Why convert BMP to AVIF?

BMP is a legacy Microsoft image format that stores raw, uncompressed pixel data. It's still found in Windows software and embedded systems, but creates massive files compared to modern formats. AVIF is the newest mainstream image format, based on the AV1 video codec. It compresses 30–50% smaller than WebP and 50%+ smaller than JPG at the same quality — the leader for modern web performance. Converting from BMP to AVIF is useful when you need cutting-edge web performance and seo or want to take advantage of best-in-class compression.
