How do I convert a CAF file to M4A step-by-step?

Open the LetsConvert CAF to M4A tool, upload your CAF file (either drag-and-drop or via file browser), optionally adjust the output audio bitrate (default 256 kbps AAC), and click 'Convert'. After processing, download the resulting M4A file. The entire conversion happens client-side in your browser, so no upload is required for files under 200 MB.

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

CAF (Core Audio Format) is Apple's uncompressed audio container, often used in recording and editing. M4A with AAC encoding is a compressed format that reduces file size by up to 90% while maintaining near-perfect audio quality for playback. M4A is supported by virtually all modern devices, media players, and web platforms, whereas CAF requires special software (such as Final Cut Pro or GarageBand). Converting saves space and ensures your audio plays everywhere without compatibility issues.

Does converting CAF to M4A preserve the original audio bitrate and metadata?

LetsConvert retains the source sample rate, bit depth (for PCM), and channel layout during conversion. The encoder uses AAC-LC at a configurable bitrate (default 256 kbps), which is transparent for most content. Metadata such as track title, artist, album, and cover art is copied to the M4A container. However, if your CAF file uses a sample rate above 96 kHz, it will be resampled to 96 kHz to stay within AAC's range. For archival lossless conversion, choose the ALAC encoder in settings, which preserves 100% of the original audio data.

Yes, CAF-TO-M4A on LetsConvert is 100% free with no registration or hidden fees required.
