How to stream video files on your phone or tablet

To stream a video on your Android device:

The Dropbox Android app uses the native Android operating system video player. Many of the videos in your Dropbox may already be supported, depending on your device and version of the Android operating system.

To stream a video on your iOS device:

When connected to the internet, the Dropbox iOS app will play just about any type of video file you throw at it. We use Apple's HTTP Live Streaming (HLS) protocol, which has been specially designed to stream files to your iPhone or iPad. The quality of the stream will depend on the speed of your wireless connection.


  • DRM-protected video files cannot be previewed.
  • Video codec created via GoToMeeting can be previewed.
  • If a video is not supported natively, there are many applications available designed to encode them to play properly. We recommend the free Handbrake desktop application (for Windows, Mac, and Linux). Read Handbrake's online documentation for detailed information about how to convert for your mobile device.

How to stream audio files on your phone or tablet

When you play an audio file in the Dropbox app, you can listen to supported audio types. You should be able to minimize the app and still hear playback. However, a couple of notes on usability:

  • The Dropbox app is not designed to be a fully-featured media player, so if you're playing items from a folder of audio files, it will not progress automatically to the next file.
  • Playback will also stop if the app is open and you load a different file or exit from the playback screen.

How to play Dropbox media files when you're offline

The media player in the Dropbox application uses the Dropbox servers to stream and transcode media. If you're offline, Dropbox will default to your device’s media player. This means that non-native files (those not filmed or recorded on your device) may not play in our application when you're offline.
