How do I convert M4A to CAF using LetsConvert?

Upload your M4A file, select CAF as the output format, and optionally adjust settings like sample rate or codec. Click 'Convert' and download the resulting CAF file. Batch conversion is also available for multiple M4A files.

Why should I convert M4A to CAF instead of keeping the original file?

CAF is Apple's native audio container for Core Audio, supporting more codecs, channels, and metadata. Converting to CAF ensures compatibility with macOS/iOS development tools, audio editors, and game engines that rely on CAF for high-fidelity audio.

Does the conversion preserve the audio codec and bitrate exactly?

Yes, when the M4A contains AAC or ALAC, the audio stream is remuxed directly into the CAF container without re-encoding, keeping bitrate and sample rate identical. Unsupported codecs are re-encoded to lossless PCM to prevent further quality loss, and all metadata is retained.
