🔁 Convert BMP to AVIF
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 AVIF. AVIF is one of the most efficient image formats, often noticeably smaller than WebP or JPG at the same visual quality, with transparency support. Support is good in current browsers but not yet universal across older devices and apps.
Going from BMP (uncompressed raster) to AVIF (lossy or lossless raster) keeps your picture intact while moving to a format that can also store transparency if you need it later.
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.
