Free online WAV to CAFF converter

Source format: WAV

WAV (Waveform Audio File Format) is a widely used uncompressed audio container developed by Microsoft and IBM. It is common in audio production, editing, archiving, and sample libraries because it preserves high quality and is easy for software to read. WAV files often contain PCM audio, which makes them ideal as a source format when you want to convert audio without introducing extra compression artifacts.

Target format: CAFF

CAFF (Core Audio Format) is an Apple audio container designed for high-quality audio storage and flexible metadata support. It is used mainly in macOS and iOS workflows, especially in professional audio applications and Apple-oriented media pipelines. CAFF can store uncompressed audio and other audio encodings, and it is useful when you need a format that integrates well with Apple software and preserves audio fidelity.

How to perform the conversion

The most reliable way to convert WAV to CAFF is with FFmpeg, which supports both formats and is available on Windows, macOS, and Linux.

1. Install FFmpeg if it is not already available on your system.
2. Open a terminal or command prompt.
3. Run a command like ffmpeg -i input.wav output.caf.
4. Check the resulting output.caf file in a compatible audio player or editor.

If you prefer a graphical workflow, some audio editors and converters can export to CAFF. In such programs, the process is usually File → Open to load the WAV file, then File → Export or File → Save As and choose CAFF or Core Audio Format as the output type.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and compatibility

WAV to CAFF is usually a lossless container conversion if both files use the same uncompressed audio encoding, such as PCM. That means the audio quality should remain unchanged. However, compatibility can vary: CAFF is less universally supported than WAV, so some players and editors may not open it. If you need maximum compatibility, WAV is usually the safer delivery format; if you need Apple-oriented workflows or Core Audio support, CAFF is a good choice.
