Convert your M4A audio files to ALAC (Apple Lossless Audio Codec) format using our free online tool. ALAC provides lossless audio quality while maintaining compatibility with Apple devices like iPhone, iPad, and Mac. No Signup Required.
M4A is a container format that typically holds audio encoded with either AAC (lossy) or ALAC (lossless) codecs. Most M4A files use the AAC codec, resulting in smaller file sizes with some quality loss.
ALAC (Apple Lossless Audio Codec) is a lossless audio codec developed by Apple that offers exact audio reproduction while typically reducing file size by 40-60% compared to uncompressed audio.
Converting from M4A (AAC) to ALAC won't recover any quality lost during the original AAC compression, but it prevents further quality loss when playing on Apple devices.
ALAC files are stored in an M4A container and are fully compatible with iTunes and Apple devices, making them ideal for Apple ecosystem users.
Converting M4A to ALAC involves transcoding from (typically) a lossy codec to a lossless one. While this can't restore already lost audio data, it ensures no further quality loss occurs.
The conversion process involves decoding the M4A (AAC) data to PCM (uncompressed audio) and then encoding it to ALAC format, preserving the audio quality as it exists in the M4A.
ALAC files will typically be larger than AAC M4A files because they don't discard any audio information during compression.
This conversion is especially useful for Apple users who want to maintain their audio library's current quality while ensuring compatibility with iTunes, iOS devices, and macOS.
ALAC supports high-resolution audio, though the converted file will retain the original sample rate and bit depth of the source M4A.
Pro Tip: Converting from M4A to ALAC is ideal for Apple users who want to maintain their current audio quality while ensuring compatibility with iTunes, iOS devices, and macOS. While it can't recover quality already lost in AAC compression, it prevents any further quality loss.
ALAC (Apple Lossless Audio Codec) provides better audio quality while maintaining compatibility with Apple devices. Converting from M4A to ALAC allows you to have a high-quality version for your Apple ecosystem devices.
While converting from M4A to ALAC won't recover quality lost in the original M4A compression (if it was lossy AAC), it prevents further quality loss when playing on Apple devices. The ALAC format will preserve the M4A's quality without additional degradation.
