App Preview Video Converter takes the hassle out of producing videos to use as App Previews on the iOS and Mac App Stores. 

Having a video demonstrating your app is a great way of improving your listing, but if you've ever tried to upload a video to App Store Connect you will have found that there's a very specific set of requirements for your masterpiece of cinematography to be accepted. Don't waste your time searching through documentation and StackOverflow for what might be causing your files to be incompatible; just use this app. 

With one click your video and audio tracks will be re-encoded into the ideal format; guaranteed to upload successfully. 

App Preview Converter is also able to resize your video into all the different resolutions on the Apple App Store. This allows you to record your video just once and use App Preview Converter to turn it into the perfect format for every device.

Make sure your listing is as great as it can be with videos formatted specifically for the device it's being viewed on.

App Preview Converter also validates your video for you to prevent failed uploads due to requirements such as length. Should your video not meet Apple's length requirements, you can even trim the video without leaving the app. 

Preview Video Converter accepts most common video file formats as inputs, with more coming soon.
