Convert M4V to AIFF — Free Online Converter

M4V, Apple's DRM-capable video container, stores H.264 video with AAC audio — the standard codecs for iTunes Store purchases and Apple TV content. AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, storing raw PCM data at full CD quality or higher. Converting M4V to AIFF extracts the audio track and decodes it to uncompressed PCM, producing a lossless representation of the sound at the cost of significantly larger file sizes.

AIFF provides bit-perfect, uncompressed audio that professional audio workstations like Logic Pro, Pro Tools, and GarageBand can import directly without any codec overhead. If you need to edit, remix, or master audio extracted from M4V video content on macOS, AIFF is the native uncompressed format that integrates seamlessly with Apple's audio production ecosystem.
