Use Compress Videos to shrink the file size of videos and regain storage space on your device.  Compress Videos works with all video file types supported by your iPhone, including H. 264, MPEG-4, HEVC, . m4v, . mp4, and . mov.  Save storage space on your iPhone or iPad by compressing your videos and reducing their size without reducing their quality.  The intelligent compression engine allows you to reduce the file size of videos without reducing their quality.  With two compression settings to choose from, Compress Videos can easily shrink your videos by 90% or more without a notable difference.  When applied to all your videos, Compress Videos can help you store up to 10 times more videos on your iPhone or iPad.  Compressed videos are saved to both your main library and a dedicated album conveniently called “Compressed Videos” on your device, allowing you to easily locate processed footage.  Upgrade to the Pro version of Compress Videos to remove ads, compress more than one video at a time, and compress unlimited videos daily.  Compress Videos is easy to use but it is incredibly powerful.  For best results, we recommend setting frame rate at 24 and video dimensions at 80%, which should significantly reduce the file size without a noticeable difference to the naked eye.  This new album is automatically created when you run the app and save compressed videos to your device.  It helps me save a lot of memory on my phone by compressing all my videos and photos.  Payment will be charged to your iTunes account at confirmation of purchase and will auto-renew at the same price every year, unless canceled in your iTunes account settings at least 24 hours before the end of the current period.  Are you plagued by the “Storage almost full” alert on your iPhone or iPad?  "Don’t waste time with other apps.  The compression is quick and design is user friendly".
