How do I make an iPhone ringtone?

Cut a clip of up to 30 seconds, then convert it to M4A with the Audio converter and rename the file to .m4r before adding it in iTunes/Finder or GarageBand.

Can I cut several parts from one file?

Run the cutter once per clip — each run takes a few seconds. Joining clips is coming later.

The clip is re-encoded once. At 192 kbps or higher the difference from the source is inaudible; choose 320 kbps to be safe with music.

No. Decoding and encoding happen in your browser.

Type where the clip should start and end, and get just that piece as a new MP3 — a 30-second ringtone from a song, the intro of a podcast, or a voice memo without the first ten seconds of fumbling.

Runs in your browser — files never leave your device.

Why convert MP3 to MP3

MP3 is made of independent frames, so cutting is a matter of decoding the file, keeping the samples between your start and end points and re-encoding them with the LAME encoder at the bitrate you pick. The tool runs the whole chain in your browser through WebAssembly.

Because the clip is re-encoded, it is frame-accurate to a hundredth of a second — no keyframe rounding — and you can lower the bitrate at the same time to make a ringtone or voice clip smaller.

How to convert MP3 to MP3

Drop the MP3 onto the page.
Enter the start and end time in seconds (e.g. 45 to 75 for a 30-second ringtone).
Choose the bitrate, click Cut and download the clip.
