M4A → AIFF. Source file ≤ 100 MB · Output ≤ 100 MB.

M4A output contains AAC audio without a video track. AIFF output contains uncompressed 16-bit PCM audio.

M4A → AIFF: Example settings

60 s × 48,000 Hz × 2 ch × 16 bit ÷ 8 = 11.52 MB (PCM)

AIFF: Output

Sizes are examples, not guarantees. Container overhead is extra; variable bitrate and image content change the result. Keep the original and compare the output.
