iTunes Video and QuickTime Movie exist for different jobs: M4V is Apple’s iTunes video format — essentially MP4 that may carry FairPlay DRM, which is why non-Apple players sometimes reject it. MOV keeps high production quality, which makes it a favourite intermediate format for video editing before final export.

This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the M4V format

M4V is Apple's variant of MP4, distinguished by an optional DRM layer (FairPlay) used by iTunes movie purchases, plus chapter flags. A DRM-free M4V is byte-for-byte the same beast as MP4 — rename the extension and most players never notice. Apple TV, iTunes and QuickTime treat it as first-class.

Outside Apple's world it buys you nothing: DRM-protected files are locked to authorized devices by design, and non-protected ones are just MP4. Converting M4V to MP4 is only meaningful to drop the extension or to strip DRM you are entitled to remove in your own jurisdiction — DRM-locked store purchases remain locked.

+ Strengths

  • ✓Native to iTunes/Apple TV/QuickTime

  • ✓DRM-free files equal MP4 in every way

! Limitations

  • −Store purchases are DRM-locked to Apple devices
  • −Redundant with MP4 outside Apple ecosystems

About the MOV format

MOV is Apple's QuickTime container, and technically the elder sibling of MP4 — same ISO base media format, same codec freedom. What sets it apart is professional video: ProRes intermediate codecs, timecode tracks and alpha channels live in MOV, which is why Final Cut, Premiere and every camera that shoots Apple ProRes hand you MOV files.

For everyday sharing it behaves exactly like MP4 (an H.264 MOV is interchangeable in practice). Where it hurts is size: ProRes and other editing codecs run hundreds of gigabytes per hour by design — they prioritize frame-accurate editing over compactness.

+ Strengths

  • ✓Native to macOS, iOS and pro editing suites
  • ✓Carries ProRes, alpha and timecode tracks
  • ✓MP4-compatible for standard codecs

! Limitations

  • −Editing codecs produce enormous files
  • −ProRes playback needs capable hardware/players

Frequently asked questions

Is this M4V to MOV converter really free?

Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.

Are my files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.

Does it work on Windows, Mac, iPhone and Android?

Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.

Is there a file size limit for M4V to MOV?

The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.

Why is video conversion slower than image conversion?

Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.

Does converting M4V to MOV re-encode my video?

Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
