Free online MP2 to ALAC converter

Source format: MP2

MP2 (MPEG-1 Audio Layer II) is a compressed audio format that was widely used in broadcasting, digital radio, and older video production workflows. It is still found in some TV, radio, and archival files. MP2 offers efficient compression and good compatibility with legacy hardware, but it is less common today than MP3 or AAC for consumer audio.

Target format: ALAC

ALAC (Apple Lossless Audio Codec) is a lossless audio format developed by Apple. It preserves the full audio signal while reducing file size compared with uncompressed PCM/WAV. ALAC is commonly used in Apple devices, iTunes/Music libraries, and archival collections where keeping original quality matters.

How to perform the conversion

The best practical method is to use a desktop audio converter or a command-line tool that can decode MP2 and encode ALAC. Because ALAC is lossless, the conversion will not improve the original MP2 quality; it only stores the decoded audio in a lossless container.

Option 1: FFmpeg

FFmpeg is one of the most reliable tools for this task and supports both formats directly.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt.
3. Run a command such as ffmpeg -i input.mp2 -c:a alac output.m4a.
4. Check the resulting file in an audio player that supports ALAC.

If you want to preserve metadata when possible, FFmpeg usually copies common tags automatically. You can also use output.m4a or output.mp4 as the destination filename, since ALAC is commonly stored in an M4A/MP4 container.

Option 2: Audacity with export tools

1. Open the MP2 file in Audacity.
2. Verify that the audio imports correctly.
3. Use File → Export → Export Audio.
4. Choose an ALAC-capable export format if available through your installed codecs or use a workflow that exports to a lossless intermediate first, then encode with FFmpeg.

Option 3: Convert online on 101convert.com

You can convert the file on 101convert.com for free, without installing any software. Upload the MP2 file, choose ALAC as the output format, and download the converted file when processing is complete.

Notes on quality, compatibility, or limitations

MP2 is lossy, so converting it to ALAC does not restore lost audio detail. The resulting ALAC file will be larger than the original MP2 because it stores the decoded audio in a lossless format. This conversion is useful for Apple ecosystem compatibility, long-term storage, or editing workflows where a lossless format is preferred after decoding.

For best compatibility, save ALAC in an .m4a container rather than a raw audio extension. Some older players may not support ALAC, while modern Apple software and many current media players do. If the MP2 source has low bitrate or artifacts, those imperfections will remain audible in the ALAC output.
