Audio Cutter & Ringtone Maker

Cut a song or recording on its waveform, fade it in and out, and save an MP3 for Android or an M4R ringtone for iPhone. Your music never leaves your device.

MP3, M4A, WAV, OGG, FLAC, or the sound of a video

Making a ringtone in four steps

  1. Choose a song or recording: MP3, M4A, WAV, OGG, FLAC, or a video whose sound you want. The waveform appears and the first 30 seconds are selected.
  2. Drag the handles on the waveform to the part you want, or type the start and end times. Press Play the selection to hear exactly what you are keeping.
  3. Add a fade. A fade in of 1 or 2 seconds avoids a sudden blast when the phone rings; a fade out (2 seconds to begin with) stops it ending abruptly.
  4. Choose the format for your phone and save.

A good ringtone starts strongly, so pick a moment where the tune or chorus is already going rather than a quiet introduction. 20 to 30 seconds is usually plenty: most calls are answered or missed well before that.

Which format for which phone

FormatUse it forNotes
MP3Android ringtones, alarms and notification soundsPlays on everything
iPhone ringtone (M4R)iPhone ringtonesAAC sound, at most 40 seconds
M4AA short clip to keep or shareSame sound as M4R, no length limit
WAVEditing software, some upload formsUncompressed, about 10 MB a minute

For MP3, M4R and M4A you can choose 128, 192 or 256 kbps. 192 kbps is a good balance for music.

Setting it as your iPhone ringtone

Apple does not let you set a ringtone straight from a download, so there are two routes:

  • With a computer. Connect your iPhone with its cable. On a Mac, open it in Finder; on Windows, open the Apple Devices app or iTunes. Drag the .m4r file onto the iPhone. Then on the iPhone go to Settings, Sounds & Haptics, Ringtone, where it appears at the top of the list.
  • On the iPhone alone. Save the file to the Files app. Open GarageBand (free from Apple), start a new project, import the file, then use Share, Ringtone. GarageBand can also set it as your ringtone straight away.

Setting it as your Android ringtone

Save the MP3, then open Settings, Sound (on some phones Sounds and vibration), Phone ringtone, and choose it from your files. The menu names vary between Samsung, Xiaomi, Vivo, Oppo, OnePlus and others. If your ringtone does not appear in the list, move the file into the Ringtones folder using the Files app and look again. The same steps work for alarm and notification sounds.

Want the sound from a video saved whole? Use video to MP3. Need to change a file's format without cutting it? The audio converter does that, and the audio joiner puts several clips together.

The engine behind this tool

Video and sound are processed by FFmpeg, the open-source engine behind most of the world's video software, compiled to run inside your browser as ffmpeg.wasm. It is downloaded from this site (about 31 MB) the first time you use a video or audio tool, and your browser keeps it for next time. FFmpeg and ffmpeg.wasm are free software, licensed under the GNU General Public License version 2 or later; their source code is at github.com/ffmpegwasm/ffmpeg.wasm.

Frequently asked questions

Is my song uploaded anywhere?

No. The song is cut on your own device by FFmpeg compiled to WebAssembly, running inside this browser tab. The engine (about 31 MB) is downloaded from this site once and cached by your browser; your music never leaves your device.

Why can an iPhone ringtone be only 40 seconds long?

That is the limit Apple sets for ringtones. If your selection is longer, the tool saves the first 40 seconds of it as the M4R file and tells you so before you save. MP3, M4A and WAV have no such limit.

How do I set the M4R file as my iPhone ringtone?

An iPhone accepts ringtones only through a computer or GarageBand. With a computer: connect the iPhone, open it in Finder on a Mac or the Apple Devices app or iTunes on Windows, and drag the .m4r file onto it; then on the iPhone go to Settings, Sounds & Haptics, Ringtone. Without a computer: save the file to Files, import it into a GarageBand project, then use Share, Ringtone.

Can I make a ringtone from a video?

Yes. Choose the video file and the tool uses its sound. This works for iPhone and Android videos as well as MP4, MOV, MKV and WebM files.

Does cutting reduce the sound quality?

The part you keep is encoded again in the format you choose. At 192 or 256 kbps the difference is very hard to hear, but the result can never sound better than the original. WAV is uncompressed, so it adds no further loss, at the cost of a much larger file.

My Android phone does not show the new ringtone. What now?

Some phones list new ringtones only when the file is in the Ringtones folder. Move the MP3 there with the Files app, then look again under Settings, Sound, Phone ringtone. The exact menu names differ between brands.
