The iPhone and iPad can capture amazingly high definition video in 4K, 1080p, and 720p resolution, and while those movies will look fantastic they also create large file sizes. While you can always change the recording resolution of video in iOS ahead of time, another option is to compress video after the fact, thereby reducing its file size dramatically. Compressing video is helpful particularly if you want to share a video from an iPhone or iPad but you’re finding the movie file size is too large for a standard file transfer, message, or email.
We’re going to show you how to compress video on an iPhone or iPad to reduce the file size or lower the video definition quality. Compressing video is not a feature that is built into iOS natively however, so we’ll be relying on a free third party app that does the job quite well.
