Convert your AAC 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.
AAC (Advanced Audio Coding) is an audio coding standard designed as the successor to MP3, offering better sound quality at similar bit rates. It was developed by a group including Fraunhofer, Nokia, and Dolby.
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.
Unlike AAC which is lossy, ALAC preserves 100% of the original audio data, making it perfect for audiophiles and professional applications where sound quality is paramount.
ALAC files are stored in an M4A container and are fully compatible with iTunes and Apple devices, while also supporting rich metadata including album artwork and detailed song information.
Converting AAC to ALAC involves both a codec change and container modification. The lossy AAC audio is re-encoded into the lossless ALAC format.
While converting from a lossy format (AAC) to a lossless one (ALAC) won't recover lost audio data, it prevents further quality degradation in future edits or conversions.
ALAC files are typically larger than AAC files because they preserve all audio data, but they're still smaller than uncompressed formats like WAV or AIFF.
This conversion is especially useful for archiving important audio or for use in professional audio workflows where maintaining the highest possible quality is critical.
ALAC supports high-resolution audio up to 32-bit/192kHz, though the converted file will retain the same sample rate and bit depth as the source AAC.
Pro Tip: Converting from AAC to ALAC is ideal when you want to archive important audio files or use them in professional audio workflows. While this conversion won't recover quality already lost in the original AAC compression, it prevents further quality loss in future edits or conversions.
ALAC (Apple Lossless Audio Codec) provides lossless audio quality while maintaining compatibility with Apple devices. Converting from AAC to ALAC allows you to get higher quality audio for archiving or professional use while ensuring compatibility with the Apple ecosystem.
While converting from AAC (which is lossy) to ALAC (which is lossless) won't recover audio quality that was already lost in the AAC compression, it prevents further quality loss in future conversions. ALAC preserves the quality of the source at its current level.
Conversion time depends on the original file size. Most conversions complete within a few minutes or less.
