Free online OGG to CAFF converter

Source format: OGG

OGG is a container format most commonly used for audio, especially with the Vorbis or Opus codecs. It is widely used by musicians, podcasters, game developers, and anyone who wants efficient, open, royalty-free audio compression. Typical uses include music distribution, voice recordings, streaming audio, and game sound assets.

Target format: CAFF

CAFF stands for Core Audio Format, an Apple audio container designed for high-quality audio storage on macOS and iOS systems. It can store uncompressed or compressed audio and is useful in Apple-centric workflows, audio editing, and archival tasks where compatibility with Core Audio tools matters. Its main advantages are flexibility, support for metadata, and strong integration with Apple software.

How to perform the conversion

The most reliable way to convert OGG to CAFF is with FFmpeg, which supports both formats and gives you control over the output codec. If you only need a quick conversion and do not want to install software, you can convert the file on 101convert.com for free.

1. Install FFmpeg if it is not already available on your system.
2. Open a terminal or command prompt in the folder containing your OGG file.
3. Run a conversion command such as ffmpeg -i input.ogg -c:a pcm_s16le output.caff to create a CAFF file with uncompressed 16-bit PCM audio.
4. If you want a smaller file and your target application supports it, you can try a compressed codec supported by CAFF, but PCM is the safest choice for compatibility.
5. Open the resulting output.caff in a compatible Apple audio tool or player to verify that the audio plays correctly.

In Audacity, you can also import the OGG file and export it through File → Export → Export Audio, then choose a CAFF-compatible format if your installed export options support it. However, FFmpeg is usually the most dependable method for this specific conversion.

Notes on quality, compatibility, or limitations

OGG to CAFF conversion is usually a format change rather than a quality improvement. If the source OGG uses a lossy codec such as Vorbis or Opus, the audio quality cannot be restored beyond what is already in the file. For best results, convert to uncompressed PCM inside CAFF to avoid adding another layer of lossy compression.

Compatibility can vary because CAFF is less universally supported than OGG. It is best suited for Apple software and workflows that explicitly support Core Audio containers. Some players and editors may not recognize .caff files even if they can handle the underlying audio codec. If broad playback compatibility is important, consider keeping a copy in OGG or converting to a more widely supported format instead.
