DivX to M4V Converter
Processing entirely on your device — large files may take a moment.
DivX is the MPEG-4 ASP profile that defined movie sharing and DVD-player compatibility in the 2000s — most "AVI movies" of the era are DivX. Converting M4V to MP4 removes the compatibility friction while keeping quality.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the DivX format
DivX was the codec that made movie-sharing possible on a CD-R: MPEG-4 ASP at a bitrate that fit a 90-minute film into 700MB. The .divx container is DivX's own variant of AVI with chapter and menu extensions, and a decade of downloaded movies carry it.
Conversion to MP4 is straightforward — the MPEG-4 ASP video decodes through ffmpeg and re-encodes to H.264 at half the size for phones and smart TVs that never learned the DivX profile.
+ Strengths
- ✓Enormous installed base of content
- ✓Hardware players supported it for a decade
- ✓Decodes cleanly via ffmpeg
! Limitations
- −QPEL/GMC profiles break some decoders
- −MPEG-4 ASP artifacts at low bitrates
- −Superseded by H.264 everywhere
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 DivX 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 DivX 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 DivX 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 DivX file has multiple audio tracks, the first one is used.
