MOV
QuickTime File FormatApple's QuickTime container, and the format an iPhone records to. MP4 was derived directly from it, so the two are structurally close — converting between them is often a fast remux rather than a full re-encode.

FLAC

- MOV is lossy and FLAC is lossless. Re-saving cannot recover details removed by the lossy source. The output is usually larger with similar visible quality, not a repaired original.
- Only the audio track survives this conversion — the picture is discarded entirely.
Questions about converting MOV to FLAC
Is this MOV to FLAC converter free?
Yes. Converting MOV to FLAC here is free, with no account, no watermark and no daily quota. The work runs on your own device, so there is no server cost to pass on to you.
Is my MOV file uploaded anywhere?
For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
Is there a file-size limit for MOV to FLAC?
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
Does converting MOV to FLAC lose quality?
Nothing is intentionally discarded in this step, because FLAC is lossless. A MOV file encoded with lossy settings stays lossy, so missing detail is not recovered.
Can I convert several MOV files to FLAC at once?
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
Does MOV to FLAC work on a phone, Mac or Chromebook?
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
