MKV 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 MKV format, this page is the shortcut: MKV (Matroska) is the open container of choice for HD movies: it holds virtually any video/audio codec plus subtitles and chapters in one file.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the MKV format
MKV (Matroska) is the open container that refuses to say no: virtually any video codec, multiple audio tracks, multiple subtitle streams, chapters, attachments and menu structure in one file. It became the de facto standard for movie rips, anime releases and personal archives precisely because nothing needs to be thrown away.
The same generosity is its compatibility risk: smart players (VLC, mpv) handle everything, but smart TVs, consoles and car systems choke on exotic codec combinations inside MKV. It is also not a streaming standard, so web delivery runs through its subset, WebM.
+ Strengths
- ✓Unlimited tracks: audio, subtitles, chapters, attachments
- ✓Open specification, no licensing
- ✓Ideal archival container — nothing is lost
! Limitations
- −Device playback is hit-or-miss outside smart players
- −Not web/streaming native
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

Frequently asked questions
Is this MKV 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 MKV 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.
Does converting MKV to M4V 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.
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 MKV file has multiple audio tracks, the first one is used.
