The open alternative to MP3

iPhone Ringtone
The iPhone ringtone format
M4R is an M4A (AAC) file with a different extension, which iPhones recognize as a ringtone or alert tone. iOS accepts ringtones of up to 40 seconds.
Audio is converted by ffmpeg running inside your browser. Your files never reach a server.
Queue up to 50 files and download them one by one or together as a ZIP.
Set the bitrate, bit depth, sample rate and channels — or simply keep the sensible defaults.
Add your OGG files to the converter above. M4R is already selected as the output, so conversion starts right away. When a file is ready, click Download, or use Download all to get a ZIP.
The audio is encoded as AAC at 256 kbps, which sounds excellent through a phone speaker. Only the first 40 seconds are kept, unless you turn that option off.
The defaults (AAC at 256 kbps, first 40 seconds) are ideal. Then connect your iPhone to a computer and drag the file into Finder or iTunes, or share it to GarageBand on the phone and export it as a ringtone.
No. The OGG to M4R conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your files are never sent to a server, so even private recordings stay on your device.
Yes. Add up to 50 files; they are converted one after another, and you can download each M4R file separately or all of them together as a ZIP archive.
