Quick answer: On iOS 26, save a short MP3 or M4A (30 seconds or less) to the Files app, tap it, tap Share, then Use as Ringtone. On iOS 18 and earlier, build the clip in GarageBand and use Share › Ringtone. Either way, the clip has to be 30 seconds or shorter and can’t be a copy-protected Apple Music song.
Check which method your iPhone uses
Open Settings › General › About and look at the iOS version. iOS 26 added a direct way to turn an audio file into a ringtone. Anything older still goes through GarageBand, which is free from Apple.
The iOS 26 way: Use as Ringtone
- Get the sound onto your iPhone as an MP3 or M4A file in the Files app. A voice memo works too, straight from the Voice Memos app.
- Make sure it’s 30 seconds or shorter. Longer files are refused with a “too long” message.
- Tap the file, tap Share, scroll down and tap Use as Ringtone.
- Settings opens with it set as your ringtone. It also appears in Settings › Sounds & Haptics › Ringtone, so you can switch back any time or pick it as a text tone.
The hard part is step 2. Most songs are three minutes long, and the bit you want is usually the chorus, not the first 30 seconds. iOS doesn’t include a tool to cut an MP3 down.
The older way: GarageBand
Apple’s own steps for iOS 18 and earlier:
- Open GarageBand and start a new audio recording.
- Open the Loops browser, choose Files (or Music for a downloaded, non-protected song) and drag the sound into a track.
- Drag the edges of the region to trim it, and move it to the very start of the track.
- Go to My Songs, select the project, tap Share › Ringtone and name it.
- If it’s over 30 seconds, GarageBand offers to shorten it. Tap Export, then Use sound as to set it as your ringtone, text tone, or a contact’s tone.
It works, but it’s a lot of steps for a phone call sound, and trimming in GarageBand’s track view is fiddly on a small screen.
Which sounds make good ringtones
- Start on the hook. A ringtone that opens on a quiet intro sounds like nothing in a noisy room.
- Add a short fade in and out. It stops the click you hear when audio is cut mid-wave.
- Loud and clear beats long. Ten punchy seconds are better than thirty quiet ones, because the tone repeats anyway.
