Free online CAFF to OGA converter

Source format: CAFF

CAFF stands for Core Audio Format File, an Apple audio container format used mainly on macOS and iOS systems. It is designed to store audio data with high flexibility and can hold uncompressed or compressed audio, along with metadata such as markers and channel information. CAFF is most often encountered in professional audio workflows, sound libraries, and Apple-based applications that need a modern alternative to older audio containers.

Because CAFF is not as widely supported as common consumer formats, users often convert it when they need broader playback compatibility or easier sharing across platforms.

Target format: OGA

OGA is an audio file extension commonly used for Ogg Vorbis audio streams inside an Ogg container. It is an open, royalty-free format with good compression efficiency and broad support in media players, web tools, and open-source software. OGA is useful for music, voice, and general audio distribution when you want a compact file without relying on proprietary formats.

Compared with CAFF, OGA is typically smaller and more portable, making it a practical choice for playback on many operating systems and devices.

How to perform the conversion

The most reliable way to convert CAFF to OGA is with FFmpeg, which supports both formats and preserves audio quality as well as the source allows.

1. Install FFmpeg on your computer if it is not already available.
2. Open a terminal or command prompt in the folder containing your CAFF file.
3. Run a command such as ffmpeg -i input.caff -c:a libvorbis output.oga.
4. If your CAFF file uses a codec that FFmpeg can decode directly, the audio will be re-encoded into Ogg Vorbis and saved as output.oga.

If you prefer a graphical workflow, you can also use audio editors or converters that support both formats, then choose File → Export or File → Save as and select an Ogg/Vorbis or OGA output option. On 101convert.com, you can convert the file for free without installing any software.

Notes on quality and compatibility

CAFF to OGA is usually a lossy conversion because OGA commonly uses Vorbis compression. That means some audio detail is discarded during export, so repeated conversions should be avoided. If the source CAFF contains uncompressed audio, the resulting OGA will usually be much smaller but not bit-for-bit identical.

Metadata support may also change during conversion. Tags, markers, and specialized CAFF information may not transfer perfectly into OGA, depending on the tool used. For best results, keep the original CAFF file as an archive copy and use the OGA version for playback or distribution.
