The instructions have been checked against version 8.2.7. Some screenshots are from earlier versions, so labels, icons, or layout may differ.
Does conversion require an internet connection?
Conversion and editing are performed on the device, so ordinary file conversion does not require internet access. Advertising, in-app purchases and restoration, and the support page require a connection.
Which formats are supported?
See supported input and output formats. A file may still fail if its internal codec is unsupported or the file is damaged.
Background playback is not working
Restart the app and device, and confirm that the file is supported by the in-app player. If the problem continues, contact support with the app version, device model, and iOS version.
How do I restore a purchase?
Open the relevant purchase item on the Settings screen and select Restore. Use the same Apple Account used for the purchase and make sure the device is online.
