Convert M4V videos to MP4 for playback outside Apple ecosystem. Works with DRM-free iTunes content. Simple container remux with zero quality loss.
Conversion settings — add a file to adjust
Upload your .m4v file by dragging it into the upload area or clicking to browse.
Choose your output settings. The default settings work great for most files.
Click Convert and download your .mp4 file when it's ready.
M4V is Apple's video container format—essentially MP4 with optional DRM protection. While M4V plays perfectly on Apple devices, non-Apple devices and software often don't recognize the extension. Converting M4V to MP4 is typically a simple container remux that changes nothing but the format designation.
For DRM-free M4V files (personal recordings, converted content, unprotected purchases), conversion is instant and lossless. The video and audio streams copy exactly—only the container designation changes from M4V to MP4.
For anyone with M4V content that needs to play on Windows, Android, or non-Apple media players, this simple conversion opens universal compatibility.
Cross-platform compatibility expands. While M4V and MP4 are technically similar, some Windows software and Android devices don't recognize the .m4v extension. Converting to .mp4 ensures universal recognition.
Simplified file management. Maintaining both .m4v and .mp4 files creates confusion. Converting to the standard .mp4 extension streamlines your video library.
Software compatibility improves. Some video editors and media servers handle .mp4 better than .m4v. Converting eliminates potential compatibility quirks.
For DRM-free M4V, conversion is simple remuxing with zero quality loss.
**DRM check**: We verify the M4V file isn't DRM-protected. FairPlay-encrypted content from iTunes purchases cannot convert.
**Container remux**: For unprotected M4V, we remux the streams—copying video and audio bit-for-bit into the MP4 container. This is essentially a file rename with proper container handling.
**Metadata preservation**: iTunes metadata (title, artwork, chapter markers) transfers to MP4. Your organization and information maintains.
**Instant processing**: Remuxing is instantaneous regardless of file size. Multi-hour movies process in seconds.
This conversion is typically completely lossless. Video and audio streams copy directly without re-encoding. The M4V and resulting MP4 are bit-identical in terms of actual video/audio data. File size is essentially identical—within a few bytes for container metadata differences. DRM-protected iTunes content cannot convert—only DRM-free M4V files process.
