All about AVI files
Classic Microsoft video container
The .avi file format is a container format for audio and video files developed by Microsoft. The abbreviation .avi stands for Audio Video Interleave, which describes the technical details of the format.
As .avi files can contain various codecs (a codec is a type of algorithm in which the data is stored), an .avi file cannot always be opened on every device. Furthermore, AVI files are often very large. With our video compressor tool, you can reduce the file size. MP4 files, for example, offer better compatibility and can now be opened with almost any modern web browser. With our AVI to MP4 tool, you can easily convert the files.
