A large size drop from BMP to AVIF
Of every conversion pair offered here, BMP to AVIF has the biggest gap between source and destination. BMP stores every pixel uncompressed, while AVIF is one of the most efficient compressed formats available today. A multi-megabyte BMP screenshot or scan can often shrink to a small fraction of its original size, frequently under a tenth, depending on the image content. That is the combined effect of removing uncompressed padding and applying modern compression.
