Free online AAC to IMY converter

AAC files contain recorded audio, while IMY files are ringtone files used by phones that support the iMelody format. Convert an AAC file when a compatible phone or ringtone tool requires IMY, but expect to recreate the melody rather than preserve the original recording.

What the AAC format is

AAC (Advanced Audio Coding) is a lossy audio compression format used for music, podcasts, and other recordings. It is common in files from Apple devices and apps, including iTunes and Apple Music downloads that are not protected, as well as in video and phone recordings. AAC stores sampled sound, such as voices and full musical performances.

What the IMY format is

IMY is the file extension for iMelody, a text-based ringtone format used on some mobile phones. It represents a sequence of notes, rests, and timing instructions rather than recorded sound. Its small, simple melody data suits basic ringtones, but it cannot carry an AAC recording’s vocals, instruments, or full audio quality.

How to convert AAC to IMY

Online on 101convert.com

1. Open the AAC-to-IMY converter on 101convert.com and upload the AAC file. Multiple files can be added for batch conversion; the page shows the per-file size limit.
2. Start the conversion and wait for it to finish.
3. Download the resulting IMY file and test it on the intended phone or ringtone tool.

Offline with desktop software

There is no direct, lossless AAC-to-IMY conversion: AAC contains recorded sound, but IMY can encode only a simple note sequence. For an offline recreation, use Audacity (Windows, macOS, or Linux) to listen to the AAC and work out a single melody, then use a plain-text editor to write that melody in iMelody format and save it with an .imy extension. Audacity can help inspect the audio, but it does not export IMY; the notes and timing must be transcribed and entered manually according to the iMelody specification.
