iOS 26 and iPadOS 26 allow users to use any 30-second audio file in various formats as ringtones on their iPhone or iPad.
To set an audio file as a ringtone, open the file in the Files app or a third-party file manager app, select 'Use as Ringtone,' and follow the prompts in the Settings app.
Deleting the original audio file does not remove the created ringtone; users can delete added tones by going to Settings > Sounds & Haptics > Ringtone.
Users on older iOS versions have limited options for custom ringtones, including purchasing from iTunes, using GarageBand, or creating ringtones with specific tools.
