When to Convert
Common scenarios where this conversion is useful
Archive audio from iPhone video recordings
iPhone videos saved as MOV files often contain high-quality AAC audio. Convert to FLAC to archive the audio track from memorable moments — concerts, speeches, performances — without any further quality loss.
Extract audio from Final Cut Pro exports
Final Cut Pro exports are often MOV containers. Extract the audio as FLAC to create a lossless audio archive of your video production's audio mix for distribution, broadcast delivery, or long-term storage.
Create lossless audio from Mac screen recordings
macOS screen recordings are MOV files. If you record voiceovers, tutorials, or presentations, extracting to FLAC gives you a lossless audio file for editing in any DAW without introducing codec artifacts.
Preserve concert audio from iPhone video
Concert videos recorded on iPhone in MOV format capture audio at high quality. Convert to FLAC for a lossless archive of the performance audio that can be organized in music libraries with full metadata.
Extract dialogue from QuickTime movie files
Film and video producers working with MOV source files can extract dialogue, narration, or sound design tracks as FLAC for lossless audio review, transcription, or archiving.

Frequently Asked Questions
MOV files from iPhones and modern Macs typically contain AAC audio. Professional MOV files from Final Cut Pro or cinema cameras may contain uncompressed PCM or Apple Lossless (ALAC). FFmpeg handles all of these codecs when extracting to FLAC.
If the MOV contains ALAC or PCM audio, the FLAC will be a perfect lossless copy. If the MOV contains AAC (as iPhone videos do), the FLAC stores the AAC audio without further loss — but it cannot recover quality lost by AAC encoding.
FLAC uses lossless compression and produces files much smaller than uncompressed WAV or AIFF. Audio-only FLAC is also dramatically smaller than the source MOV because the video stream is removed.
Yes. Apple added native FLAC support in iOS 11, macOS 10.13 (High Sierra), and Apple TV 4K. FLAC files play in the Music app and most third-party players on Apple devices.
Yes. Upload the MOV directly from your iPhone via the browser. ChangeThisFile works on mobile Safari. Download the FLAC file to your iPhone's Files app when done.
Chapter markers in MOV files may not transfer cleanly to FLAC metadata. FLAC supports cue sheet embedding for chapter-like navigation, but this may require manual setup with a tag editor after conversion.
FLAC is lossless and open-source. M4A uses AAC (lossy) but is more compatible with Apple devices and smaller in size. For archiving, FLAC is superior; for playback convenience on Apple devices, M4A is more practical.
Yes. ChangeThisFile is completely free. No signup, no limits, and no fees for converting any number of MOV files to FLAC.
Typically under 30 seconds for most videos. FFmpeg extracts and encodes only the audio stream, which is much faster than processing the video. Longer MOV files may take up to a minute.
Yes. All uploads use HTTPS encryption and files are automatically deleted from our servers immediately after you download the converted FLAC. We never retain or access your content.
