DivX to W64 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. Convert W64 recordings to WAV or FLAC for standard editors.
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- −Superseded by H.264 everywhere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 W64 format
W64 is Sony's Wave64 — what happens when WAV's 32-bit size fields run out of road. A RIFF variant with 64-bit offsets, it shrugs off the 4 GB ceiling that makes plain WAV choke, which is why long field-recording sessions and Sony Vegas projects land in W64.
Inside, it is the same uncompressed PCM as WAV — ffmpeg hands W64 to WAV, FLAC or MP3 without touching a single sample, so conversion is purely about container compatibility.
+ Strengths
- ✓No 4 GB size ceiling — hours-long recordings
- ✓Bit-exact PCM, same as WAV inside
- ✓Standard in Sony Vegas workflows
! Limitations
- −Almost nothing outside Sony tools opens it
- −Uncompressed — very large files
- −Legacy niche — new tools prefer RF64
Why convert DivX to W64?
Think of it as moving your file to the container that fits the job. QPEL/GMC profiles break some decoders W64 works differently: No 4 GB size ceiling — hours-long recordings If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this DivX to W64 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 W64?
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 W64, 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.
