MOV is lossy. Converting to FLAC won't restore lost data, but gives you an uncompressed container for editing workflows. Free tier handles input files up to 20MB file size limit with a 10-second preview output. Upgrade to Pro for unlimited, full-length conversions up to 500MB file size limit.
Frequently Asked Questions
Does it matter if my MOV has AAC or ALAC audio?
Yes — for quality, not for the workflow. If your MOV holds ALAC (Apple Lossless), the FLAC output is bit-perfect (both formats are lossless). If it holds AAC (lossy), the FLAC wraps the decoded AAC losslessly — the audio is whatever the AAC was. The converter handles both automatically; you don't need to know which one your file uses.
How do I know what audio my MOV contains?
On macOS: open the file in QuickTime, choose Window → Show Movie Inspector. Format will show 'AAC' or 'Apple Lossless'. On Windows: open in MediaInfo (free download). For iPhone videos, it's almost always AAC. For Final Cut exports with 'High Quality' settings, it may be ALAC or PCM.
What's the file size difference?
FLAC is ~half the size of WAV at the same quality, and 5–10× the size of the source AAC inside the MOV. A 1-minute iPhone video with AAC audio (~1 MB of audio) yields a 5–10 MB FLAC. ALAC-source MOVs convert to FLACs of similar size to the original ALAC track.
Will the conversion preserve audio sync?
The FLAC contains only audio, so 'sync' becomes irrelevant once it's standalone. The audio's start point, sample rate, and channel layout are preserved exactly. If you re-pair the FLAC with video later, it should align frame-accurately to the original timeline.
Why not just convert to WAV?
FLAC and WAV are both lossless. FLAC is half the size, supports better metadata, and is preferred for music workflows. Use WAV if a specific tool demands it (some hardware samplers, broadcast deliverables) or if you need PCM compatibility. Otherwise, FLAC is the better default.
Can I convert iPhone Voice Memos that exported as MOV?
Yes, though Voice Memos usually export as M4A. If you have a MOV, drop it in — the converter handles MOV containers regardless of source. The output FLAC will be voice-grade audio you can edit, transcribe, or archive.
