CAF to VOC Converter
FileFlip converts CAF to VOC entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a CAF file to VOC?#
- Drop your CAF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to VOC and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the VOC file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting CAF to VOC lose quality?#
It depends on what is inside the file. CAF is a container rather than a codec, so whether the VOC conversion copies the streams across untouched or re-encodes them is decided by the codecs that particular file happens to use.
Is it safe to convert CAF files online?#
Yes, because nothing is uploaded. FileFlip converts CAF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What CAF to VOC actually does to the file#
Converting CAF to VOC runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, re-encodes or copies through depending on the codecs in the file, and drops encoded streams.

What is a CAF file?#
A CAF file holds audio in Apple's Core Audio Format, introduced in 2005 to replace AIFF and WAV on the Mac because its 64-bit chunk sizes have no practical file size or duration limit.
Keep audio as CAF while it stays inside Apple's own tools, such as Logic Pro, GarageBand, or an iOS app's own audio recordings, where the format's size and codec flexibility are used directly.
Convert CAF to WAV or M4A when the audio needs to leave the Apple ecosystem, since most non-Apple software has no built-in way to open it.
What is a VOC file?#
A VOC file holds audio in Creative Voice File format, the format Creative Labs introduced alongside the original Sound Blaster card in 1989 for storing digitized speech and sound effects in DOS-era games.
VOC mainly shows up today inside old DOS games and their emulation via DOSBox, where the original sound assets were never converted to a newer format.
Convert VOC to WAV to play or edit the audio in current software, since almost every modern audio tool reads WAV and very few still read VOC.
CAF to VOC questions people ask#
What creates a CAF file?
CAF files come from Apple's own audio software, including Logic Pro, GarageBand, and any iOS or macOS app that records audio through Apple's Core Audio APIs. Apple adopted CAF as its own format specifically to avoid the 4 GB size limit that WAV and AIFF both carry.
What still opens CAF files?
QuickTime Player, Logic Pro, and GarageBand open CAF natively on macOS, and VLC decodes it on Windows and Linux as well. Very little non-Apple software supports it directly.
What should I convert a CAF file to?
Convert CAF to WAV for lossless compatibility with editing software, or to M4A for a smaller file that still plays on non-Apple devices. Whether the conversion loses quality depends on what codec the CAF file already holds inside; a CAF containing uncompressed PCM converts to WAV with no loss at all.
What creates a VOC file?
VOC files come from Creative Labs' own Sound Blaster recording software and from DOS-era games that shipped their speech and sound effects in this format, since VOC was the native audio format for early Sound Blaster cards.
