Format description

AVI is a popular video format, created in the 90’s by Microsoft. It is short for Audio Video Interleave. When compared to other commonly used video formats, such as MOV and MP4, AVI files are usually much larger in size. This is because AVI uses less efficient compression.

To free up space on your device, you can convert AVI videos to more efficient formats like MP4 and WebM.
