DivX to AVI Converter
Processing entirely on your device — large files may take a moment.
DivX Video and AVI Video exist for different jobs: 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. Some legacy systems and DVR/camera devices only accept AVI input.
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 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- −Superseded by H.264 everywhere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 AVI format
AVI (Microsoft, 1992) is one of the oldest video containers still encountered. It has no native understanding of modern features — variable frame rates, modern codecs, subtitles, chapters — and stores everything through a 32-bit indexing system that caps reliable file sizes around 2 GB (OpenDML extensions patched some of this). Most AVIs you meet today are DivX/Xvid-era rips or old capture-card output.
There is no reason to produce AVI today; the realistic task is converting old libraries into MP4, which typically cuts file size by half or more at equal or better quality.
+ Strengths
- ✓Opens in legacy Windows tooling
- ✓Simple structure, decades of player support
! Limitations
- −Obsolete: no modern codecs or features by design
- −Large overhead, ~2 GB practical ceiling
- −Codec zoo inside — playback is guesswork
Why convert DivX to AVI?
There is a concrete reason this conversion exists: QPEL/GMC profiles break some decoders AVI sidesteps that — Opens in legacy Windows tooling If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this DivX to AVI 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 AVI?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of AVI, staying in sync with the video. If your DivX file has multiple audio tracks, the first one is used.
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.
