How to Trim MP3 on iPhone
No GarageBand. No app install. Trim MP3 files on your iPhone using just Safari.
Why Not Use an App?
Most iPhone apps for audio trimming are bloated with ads, require in-app purchases, or want access to your entire music library. You don't need any of that to trim a single MP3. cut.audio runs in Safari — open the page, load your file, trim, download. No App Store, no permissions, no ads.
Step by Step on iPhone
1. Open Safari on your iPhone 2. Go to cut.audio 3. Tap the Audio Cutter tool 4. Tap to browse files — select your MP3 from Files, iCloud, or another location 5. The waveform loads — pinch to zoom, drag handles to set trim points 6. Tap Play to preview 7. Tap Export, choose MP3 or WAV 8. The trimmed file downloads to your Files app
Use It for Ringtones
Want to make a ringtone from a song? Trim it to 30-40 seconds, export as MP3, then use the Settings app to set it as your ringtone. No GarageBand required. The waveform view makes it easy to find the exact part of the song you want — the chorus, the drop, or any section that sounds good in 30 seconds.
