Convert ALAC to iPad Audio — Free Online Converter

ALAC (Apple Lossless Audio Codec) is Apple's native lossless format, supported with hardware-accelerated decoding on every iPad. iPad Audio is a device-optimized preset that typically produces AAC in M4A — but since ALAC already plays natively on iPad with hardware decode support, this conversion re-encodes to AAC for significantly smaller file sizes while maintaining virtually transparent quality.

The iPad's A-series and M-series processors include dedicated AAC hardware decoders in their always-on audio processing unit. Converting ALAC to iPad-optimized AAC trades lossless fidelity for dramatic storage savings — ideal when iPad storage is limited.

While iPad plays ALAC natively, ALAC files are 2-3x larger than AAC at transparent quality. A 64 GB iPad storing ALAC music holds roughly 6,000 songs; the same iPad with AAC at 256 kbps holds 16,000+ songs. Converting ALAC to iPad-optimized AAC maximizes your music library size on iPad.

Both ALAC and AAC receive hardware decode acceleration on iPad, so battery life is comparable. The conversion is purely a size optimization — the perfect ALAC source ensures the AAC output achieves the best possible quality for the target bitrate.

FFmpeg decodes ALAC to perfect PCM and encodes to AAC-LC at 256 kbps within M4A. Since both codecs share the M4A container, all metadata — album art, lyrics, chapters, iTunes tags — transfers perfectly. The AAC encoder receives lossless PCM input, producing the best possible quality for the bitrate. iPad's A-series hardware AAC decoder handles the output natively.
