Need help?Convert M4V to MOV Online
M4V and MOV are both Apple container formats, so this conversion is usually a lightweight rewrap rather than a full re-encode — handy when you want an iTunes-style M4V to drop cleanly into Final Cut Pro, iMovie, or QuickTime Player. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.
How to Convert M4V to MOV
- Upload Your M4V File: Drag and drop your M4V into the box, or click "+ Add Files" to browse. You can queue several clips and convert them with the same settings.
- Pick a Quality Preset: Under Advanced Options, leave Quality Preset at "Very High (Recommended)" to keep the picture untouched, or pick a lower tier to shrink the output.
- Trim or Resize (Optional): Use Trim to keep only a time range, or set a Video resolution preset if you need to scale the frame down.
- Convert and Download: Click "Convert" and save your MOV. No sign-up, no watermark.

Frequently Asked Questions
Will converting M4V to MOV re-encode the video and lose quality?
It depends on the settings. M4V already stores H.264 video, which MOV supports natively, so at "Very High" quality the picture is effectively preserved through a remux. If you lower the Quality Preset, set a Specific file size, or change the resolution, the stream is re-encoded and you trade some quality for a smaller file. Leave the preset at "Very High (Recommended)" for the closest-to-original result.
Can you convert a DRM-protected M4V bought from iTunes?
No. Movies and TV shows purchased or rented from the iTunes Store can carry Apple's FairPlay copy protection, which ties playback to an authorized account. We cannot strip or bypass FairPlay, so a protected file will fail to convert. Home videos and DRM-free M4V exports (for example, from iMovie or a camera) convert normally.
Why convert M4V to MOV instead of just renaming the file to .mov?
Renaming only changes the label, not the internal structure. An M4V file is built on the MPEG-4 box layout, and while QuickTime is forgiving, some editors reject a renamed file or misread its track edit lists. A real conversion rewrites the container into a proper QuickTime structure so apps like Final Cut Pro read the tracks correctly.
Does the MOV output keep my audio track and timing?
Yes. The AAC or Dolby Digital audio in an M4V is carried into the MOV alongside the video, and the track timing is preserved. In our testing, a 1080p H.264 M4V exported from iMovie produced a MOV of nearly identical size with audio sync intact, since the streams were copied rather than re-compressed at the default preset.
My MOV file is too large to share — how do I shrink it?
MOV from a high-bitrate source can be hefty. Drop the Quality Preset a tier, or enter a Specific file size under File Compression to target an exact size. If you want to stay in MOV but squeeze the bitrate, the dedicated MOV compressor gives you finer control. To go smaller still, convert M4V to MP4 instead — MP4 is the more space-efficient sibling for sharing and uploads.
