MP4 to M4V Converter
Processing entirely on your device — large files may take a moment.
Converting M4V to MP4 removes the compatibility friction while keeping quality. If your files are still in MP4 format, this page is the shortcut: MP4 (H.264) is the universal video format: every phone records it, every browser, TV, editor and chat app plays it.
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 MP4 format
MP4 (MPEG-4 Part 14) is the universal delivery container of digital video. It wraps H.264, HEVC or AV1 video with AAC audio, and its structure — separate metadata (moov) and media atoms — is what makes streaming, seeking and fast-start playback possible. Phones, cameras, TVs, browsers and every social platform assume MP4 first.
Quality is entirely a function of the codec and bitrate chosen at encode time, so an MP4 can be a 10 Mbps HEVC master or a postage stamp. That flexibility plus total playback coverage is why nothing has displaced it in twenty years — conversion between formats almost always ends in MP4.
+ Strengths
- ✓Plays on every device and platform in existence
- ✓Streaming-ready structure (fast start, seeking)
- ✓Choice of modern codecs: H.264, HEVC, AV1
! Limitations
- −Quality depends entirely on encode settings
- −HEVC variants hit licensing gaps on some platforms
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
- ✓Chapters and metadata for video series
- ✓DRM-free files equal MP4 in every way
! Limitations
- −Store purchases are DRM-locked to Apple devices
- −Redundant with MP4 outside Apple ecosystems

Converting makes sense where the strengths of M4V meet what MP4 cannot give you. Native to iTunes/Apple TV/QuickTime Meanwhile Quality depends entirely on encode settings One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MP4 to M4V 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 MP4 to M4V?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of M4V, staying in sync with the video. If your MP4 file has multiple audio tracks, the first one is used.
