How to Convert MP4 to MOV

Converting MP4 to MOV is occasionally needed for specific Apple software (some versions of iMovie, older Final Cut Pro projects) or for QuickTime-specific workflows. Since MP4 and MOV are closely related containers, the conversion is usually a fast remux with zero quality loss.

Step-by-step instructions

  1. 1

    Method 1: FFmpeg (lossless remux)

    ffmpeg -i input.mp4 -c copy output.mov. The '-c copy' remuxes without re-encoding — zero quality loss, completes in seconds. Both MP4 and MOV support H.264 and H.265 video with AAC audio, so the data transfers directly.

    Method 2: Browser converter

    Go to formatdrop.com → Video Converter. Drop your MP4. Select MOV as output. Download.

  3. 3

    Method 3: QuickTime Player (Mac)

    Open the MP4 in QuickTime Player → File → Export As → select resolution → save. QuickTime saves as MOV (actually M4V with .mov extension). This re-encodes the video.

  4. 4

    Check if you actually need MOV

    Modern Final Cut Pro, iMovie (2013+), and all recent Apple video software accept H.264 MP4 natively. Check if your software actually requires MOV before converting — most Apple tools work fine with MP4. If the issue is codec (e.g., software requires ProRes), you need to re-encode, not just remux.

Why convert MP4 to MOV?

MOV is Apple's native video container and shares its technical foundation with MP4. Both can contain H.264, H.265, and AAC data. In practice, modern Apple software is happy with both formats. The main reason to convert MP4 to MOV is compatibility with older Apple software or specific workflow requirements (like delivering video to a client who requires .mov files for their post-production workflow).

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Will converting MP4 to MOV improve quality in Final Cut Pro?
No — the container format doesn't affect quality. If Final Cut is accepting MP4, there's no quality benefit to converting to MOV. If Final Cut is rejecting the MP4 (perhaps due to an incompatible codec), you may need to transcode to ProRes (Apple's preferred editing codec), not just change the container to MOV.
Does MP4 to MOV change the file size?
With remux (-c copy): virtually identical file sizes, just a few KB difference for the container overhead. With re-encoding: file size changes based on quality settings. For lossless-quality re-encoding: about the same size. For a compressed output: smaller.
