AIFF to CAF conversion is the process of transforming audio data stored in the AIFF (Audio Interchange File Format), an uncompressed PCM audio format commonly used on macOS and for professional audio, into Apple's Core Audio Format (CAF), a flexible container that supports large files, multiple codecs, and advanced metadata. This conversion repackages or recompresses the audio so it can take advantage of CAF features such as extended file sizes, more efficient codecs, and richer metadata support.

AIFF files have the MIME type audio/aiff and typically store uncompressed PCM audio data. CAF files use the MIME type audio/x-caf and can contain audio compressed with Apple Lossless, AAC, or other codecs. CAF is designed for high-performance audio applications on Apple platforms and supports features like file chunking and extensible metadata.
The CAF (.CAF) format is commonly used for audio. Understanding its characteristics can be helpful when converting to or from other formats like AIFF.
While specific technical details aren't available here, CAF files generally serve the purpose of storing audio effectively within their domain.

AIFF is an uncompressed audio format widely used for high-quality audio but tends to have larger file sizes. CAF, or Core Audio Format, offers greater flexibility with support for multiple codecs and better metadata handling. While AIFF files are popular in traditional audio workflows, CAF provides enhanced compatibility with Apple devices and modern audio applications.
Keep source AIFF files under recommended sizes for faster processing; aim for individual files under 250 MB for web-based converters.
To preserve original quality, choose CAF with PCM or ALAC (lossless) instead of lossy codecs; match the original sample rate and bit depth.
For large batches, use a desktop converter or command-line tool (e.g., afconvert on macOS) to avoid web upload limits and speed up processing.
Be aware that AIFF stores uncompressed PCM while CAF can store multiple codecs and metadata — converting to lossy CAF codecs will reduce file size but lose some fidelity.
