Complete tool guide
Turn part of any song into an iPhone ringtone. Choose up to 40 seconds on the waveform, keep or adjust the gentle fades, and save a genuine M4R file: AAC audio in an MP4 container, which is what iPhone expects. It is not a renamed MP3 or WAV file.
Your input is processed in the current browser tab and is not sent to the application server.
Choose or drag in a song or video. The first 40 seconds are selected automatically.
Drag across the waveform from where the ringtone should begin. The selection stops growing at 40 seconds; fine-tune it with the handles or the Start and End fields.
Preview the ringtone and adjust the fade in and fade out if needed.
Select Create ringtone and download the M4R file, then add it to your iPhone.
iPhone ringtones longer than 40 seconds are not accepted, so the selection cannot exceed that length. Text and alert tones work best at 2 to 10 seconds.
A 0.1-second fade in and 0.5-second fade out are preset. They prevent a click at the start and a hard stop when the ringtone repeats. Set them to 0 if you want a hard edge.
The file is AAC at 192 kbps and 44.1 kHz stereo in an iPod-compatible MP4 container with the .m4r extension.
Start with: song.mp3, 3:45 long, chorus starting at 1:05
song-ringtone.m4r · 0:40.00 · about 0.9 MB (AAC 192 kbps)192 kbps is 24 KB per second, so 40 seconds is about 960 KB plus a small container overhead.
Start with: clip.mov, 45 seconds long
clip-ringtone.m4r · 0:06.00Text and alert tones are most useful when they are only a few seconds long.
The usual method is to connect the iPhone to a computer and drag the .m4r file onto the device in Finder on a Mac, or in the Apple Devices or iTunes app on Windows. Then choose it in Settings > Sounds & Haptics > Ringtone. Available methods can change between iOS versions.
Android does not need M4R. Use the Audio Trimmer to save your selection as MP3 or OGG, copy it to the phone’s Ringtones folder, and select it in the sound settings.
Renaming an MP3 to .m4r leaves MP3 audio inside, which iPhone rejects. This tool encodes new AAC audio and writes the correct container.
Open the MP3, choose the section you want (up to 40 seconds), and select Create ringtone. The download is a real AAC-encoded .m4r file.
iPhone does not accept ringtones longer than 40 seconds, so the tool keeps your selection within that limit.
On a Mac, Finder handles syncing on macOS Catalina and later. On Windows, the Apple Devices app replaces iTunes for device management on supported versions of Windows.
No. Decoding and AAC encoding happen in your browser tab. Only the encoder code downloads the first time you create a ringtone.
