Xvid to W64 Converter
Processing entirely on your device — large files may take a moment.
Xvid Video and Sony Wave64 exist for different jobs: Xvid is the open-source DivX competitor — the other MPEG-4 ASP encoder behind a decade of movie downloads. 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.
How Xvid compares to W64
| Xvid | W64 | |

| Types / schema | MPEG-4 ASP + MP3 audio | PCM, any bit depth WAV supports |
| Compatibility | ffmpeg, VLC, every player | Sony Vegas, ffmpeg, Sound Forge |
| Best for | Legacy download migration | Long-duration uncompressed sessions |

About the Xvid format
Xvid is the open-source implementation of the same MPEG-4 ASP profile DivX commercialized — after the original was open-sourced following a legal scuffle, Xvid became the encoder of choice for a decade of scene releases and personal rips.
Identical migration path as DivX: decode through ffmpeg, re-encode to H.264. The video quality at its usual bitrates survives the trip better than DivX's worst files, thanks to Xvid's tunable quantization.
+ Strengths
- ✓Open-source and configurable
- ✓Enormous existing content corpus
- ✓Decodes via ffmpeg everywhere
! Limitations
- −Same ASP-era limitations as DivX
- −Packed bitstream quirks in some files
- −Development ended years ago
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 Xvid to W64?
There is a concrete reason this conversion exists: Same ASP-era limitations as DivX W64 sidesteps that — No 4 GB size ceiling — hours-long recordings If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this Xvid 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 Xvid 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 Xvid file has multiple audio tracks, the first one is used.
Does converting Xvid to W64 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.
