Free Tools and Tips to Convert AVI Files to MP4 for Kindle Fire

The Kindle Fire is a fantastic device for enjoying entertainment on the go, offering vibrant picture quality and quick responsiveness. However, it can be a bit choosy about the video formats it supports, especially when it comes to AVI files.
