AVI Compressor - How to Compress AVI Files on Mac (macOS High Sierra Included)


A number of media files are saved in AVI format. The typical downloaded AVI file will be around 700MB for an average length movie. As you can probably tell, storing such large files on your hard drive will have you running out of space quickly. As such, you may want to consider compressing your AVI files to smaller sizes/formats. General consumer converters will generally trade off quality for compression. Thus, you will get a much smaller media file with poor quality video and/or audio. If you want to retain the current quality of your AVI files after compressing them, then you might want to use AVI compressor.
