Why convert AVIF to BMP?
AVIF is new, so many apps and older devices can't open it yet.
Some older programs, printers and embedded devices only accept uncompressed BMP files.
What to expect
- BMP has no transparency, so transparent areas become white.
- BMP is uncompressed, so the file will be much larger than the original.
- Converting to BMP keeps every pixel of your AVIF, but it can't restore detail that AVIF compression already removed.

About the formats
AVIF (AV1 Image File Format, 2019) is the newest major image format, based on the AV1 video codec. It usually produces the smallest files of all, often half the size of JPG, with transparency and HDR support.
BMP (Windows Bitmap, 1990) is a simple, uncompressed Windows format. Files are large because every pixel is stored as-is, but almost any program, including very old software and embedded devices, can read it.
