When to Convert
Common scenarios where this conversion is useful
Import audio into Logic Pro projects
AIFF is the native uncompressed audio format for Logic Pro and GarageBand on Mac. Converting MOV video audio to AIFF lets you drag it directly into the Logic timeline as an audio region without any codec conversion.
Provide uncompressed audio from iPhone recordings to mastering engineers
iPhone MOV videos contain high-quality AAC audio. Convert to AIFF to give mastering engineers the cleanest possible uncompressed representation of your recording without adding further lossy encoding layers.
Extract audio from Final Cut Pro MOV for professional editing
Final Cut Pro exports MOV files. Extract the audio as AIFF to import it into Logic Pro, Nuendo, or Reaper for professional mixing and mastering without working in a lossy format.
Create AIFF samples from iPhone field recordings
iPhone is a popular field recording device for ambient sounds, foley, and location audio. Convert MOV recordings to AIFF for use as samples in Logic Pro's EXS24 sampler, Native Instruments Kontakt, or other Mac-native samplers.
Archive important video audio in Apple's native uncompressed format
AIFF is a stable, long-lived Apple format with no compression. Convert significant MOV recordings — speeches, performances, interviews — to AIFF for permanent archiving in an uncompressed form unlikely to become unsupported.

Frequently Asked Questions
The AIFF output is stored as uncompressed PCM. If the source MOV contained PCM or ALAC audio, the conversion is lossless. If the MOV contained AAC (as most iPhone recordings do), the AIFF accurately represents the AAC audio without further degradation — but AAC quality limits apply.
Both MOV and AIFF are Apple formats, but serve different purposes. MOV is a video container; AIFF is an audio-only container. Converting strips the video and provides uncompressed audio that integrates natively with Logic Pro, GarageBand, and audio DAWs.
AIFF is uncompressed. A 5-minute audio track at 44.1 kHz stereo produces approximately 50MB. Long MOV recordings convert to very large AIFF files. For lossless audio with smaller size, consider FLAC instead.
Logic Pro natively supports both AIFF and WAV. AIFF is the traditional Mac-native format and integrates seamlessly. For cross-platform compatibility with Windows-based collaborators, WAV is often preferred.
Yes. GarageBand on iPad and iPhone supports AIFF. You can import AIFF files via the Files app or directly from the Media Browser in GarageBand.
FFmpeg writes AIFF at the native sample rate and bit depth of the source audio. iPhone and Mac recordings are typically 44.1 kHz or 48 kHz at 16-bit, which will be reflected in the AIFF output.
Yes. AIFF is one of Pro Tools' primary supported formats on macOS. You can import AIFF files directly into Pro Tools sessions without any conversion.
Yes. ChangeThisFile is completely free for all conversions. No signup, no limits, and no fees.
Conversion is typically fast — usually under 30 seconds for most video lengths. FFmpeg extracts and decodes the audio without video processing, completing quickly.
Yes. All uploads use HTTPS encryption. Files are deleted automatically from our servers immediately after conversion. We never store or access your content.
