AC3 to CAF conversion is the process of transforming audio encoded in AC3 (Dolby Digital) format into CAF (Core Audio Format), Apple's flexible container for audio data. This conversion repackages or re-encodes the audio so it can be played or edited in macOS/iOS workflows and audio software that prefer CAF containers.

Keep source AC3 files under 250 MB for most free online converters; larger files may require a desktop tool or premium service.
To preserve quality, convert AC3 to CAF using a lossless option (CAF PCM or ALAC) rather than re-encoding to a lossy codec.
For multichannel AC3 (5.1), ensure the converter supports multi-channel CAF output; otherwise downmix to stereo to avoid channel loss.
Batch convert multiple AC3 files using a dedicated app or batch-capable online service to save time; check CPU load for local bulk conversions.
