Source format: ALAC
ALAC stands for Apple Lossless Audio Codec. It is a lossless audio format used to store music without quality loss compared with the original recording or CD source. ALAC is commonly used by Apple devices and software, including iTunes, Music, iPhone, iPad, and macOS audio libraries. Typical use cases include archiving music, keeping high-quality personal collections, and syncing audio within the Apple ecosystem.
Target format: M4R
M4R is an Apple ringtone format based on the MPEG-4 AAC container. It is essentially an .m4a/.mp4-style audio file with a different extension and ringtone-oriented usage. The main advantage of M4R is that it is recognized by iPhone as a ringtone file, making it the standard choice for custom ringtones and alert tones. It is typically used for short audio clips rather than full songs.
How to perform the conversion
The most practical way to convert ALAC to M4R is to use desktop audio software that can decode ALAC and export AAC/M4R, such as iTunes/Music on macOS, Apple Music, or FFmpeg. Because M4R is ringtone-oriented, you usually also need to trim the audio to 30 seconds or less before transferring it to an iPhone.
Method 1: Using FFmpeg
- Install FFmpeg on your computer.
- Make sure your source file is an ALAC file, often with
.m4aor.alacextension. - Run a command like
ffmpeg -i input.m4a -c:a aac -b:a 128k -t 30 output.m4r. - If needed, adjust the duration with
-tto keep the ringtone short. - Rename the output to
.m4rif your tool does not do it automatically.
Method 2: Using Apple Music or iTunes
- Import the ALAC track into your library.
- Trim the track to the desired ringtone length using Song Info → Options or an equivalent trim setting.
- Convert the track to AAC using File → Convert → Create AAC Version.
- Change the resulting file extension from
.m4ato.m4r. - Sync the file to your iPhone through Finder, Music, or iTunes, depending on your system.
Online conversion is also available on 101convert.com for free, without installing any software.
Notes on quality, compatibility, or limitations
ALAC is lossless, but M4R is usually AAC-compressed, so the conversion is not lossless. Some quality reduction is normal because ringtone files are meant to be small. For best compatibility, keep the file in stereo AAC, avoid unusual sample rates, and stay within the typical 30-second ringtone limit. Also, simply renaming a file to .m4r may not be enough if the audio codec is not AAC-compatible or if the file is too long for iPhone ringtone use.
