Free online IMY to FLAC converter

Some older mobile phones store ringtones as IMY files, while audio players and editing or archiving workflows may require FLAC. Converting the file renders its ringtone instructions as sound; it does not recover an original recording.

What the IMY format is

IMY is the extension commonly used for iMelody, a text-based mobile-phone ringtone format associated with older GSM handsets, including Ericsson phones. It describes a melody using notes, timing and pauses rather than storing recorded audio samples, so an IMY file is not directly playable by many desktop audio applications.

What the FLAC format is

FLAC stores digital audio with lossless compression: decoding reproduces the same audio samples that were encoded. It is useful for playback, editing and archiving when software or devices support FLAC. It cannot preserve IMY note instructions as instructions; those must first be rendered into audio.

How to convert IMY to FLAC

Online on 101convert.com

1. Open the IMY-to-FLAC converter page on 101convert.com and upload the file. The page shows the per-file size limit; multiple files can be submitted as a batch.
2. Choose FLAC as the output format and start the conversion.
3. Download the converted file when the conversion finishes.

Offline with desktop software

Common audio tools such as FFmpeg and Audacity do not directly decode iMelody files. Use an IMY-capable renderer to create a WAV file first, then convert that rendered audio to FLAC with FFmpeg. The rendered result depends on the renderer; FFmpeg handles only the WAV-to-FLAC step.

1. Open the IMY file in an iMelody-compatible renderer and export or render it as WAV. The available export steps depend on the renderer.
2. Install FFmpeg for Windows, macOS or Linux, then run ffmpeg -i rendered.wav -c:a flac output.flac. Replace rendered.wav with the exported WAV filename.

Quality and limitations

FLAC encoding is lossless for the rendered WAV, but it cannot add detail absent from the ringtone instructions. Different renderers may produce different sounds, and a WAV export may include silence or use a sample rate and bit depth chosen by the renderer.
