Xvid to CAF Converter
Processing entirely on your device — large files may take a moment.
Convert CAF files to WAV or MP3 for use outside the Apple ecosystem. If your files are still in Xvid format, this page is the shortcut: Xvid is the open-source DivX competitor — the other MPEG-4 ASP encoder behind a decade of movie downloads.
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.
How Xvid compares to CAF
| Xvid | CAF | |
|---|---|---|

| Types / schema | MPEG-4 ASP + MP3 audio | PCM/ALAC/AAC in CAF |
| Compatibility | ffmpeg, VLC, every player | afconvert, Logic Pro, ffmpeg |
| Best for | Legacy download migration | Apple pro-audio workflows |

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 CAF format
CAF (Core Audio Format) is Apple's container for pro audio: 64-bit file offsets for recordings of any length, any codec as payload (PCM, ALAC, AAC), and time-stamped MIDI-style event chunks. Logic Pro exports it and macOS system sounds ship in it.
ffmpeg decodes the common PCM/ALAC payload variants, converting CAF to WAV or MP3 for use in any non-Apple DAW, player or web player.
+ Strengths
- ✓64-bit offsets — no size ceilings
- ✓Native to Logic Pro pipelines
- ✓Flexible codec payload
! Limitations
- −Apple-centric — rare outside macOS
- −Some CAF variants (UUID chunks) unsupported
- −Tag metadata Apple-specific
Why convert Xvid to CAF?
Converting makes sense where the strengths of CAF meet what Xvid cannot give you. 64-bit offsets — no size ceilings Meanwhile Same ASP-era limitations as DivX One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Xvid to CAF 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 CAF?
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 Xvid to CAF 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 CAF, staying in sync with the video. If your Xvid file has multiple audio tracks, the first one is used.
