Older Windows versions require a specific AV1 Video Extension codec from the Microsoft Store. Converting to standard JPG lets you view the image immediately on any system.

Because standard JPG does not support alpha transparency, any transparent areas are automatically matted with your chosen background color (default is clean white).

Yes! Click the Batch tab to drop an entire folder of AVIF files and convert them all at once.
