How do I convert an MP4 file to CAF?

Upload your MP4 to the LetsConvert tool, select CAF as the output format, choose your preferred audio codec (passthrough, ALAC, or PCM), then click Convert. The converter extracts the audio track and wraps it into a CAF container. Download the resulting .caf file when complete.

What is the difference between MP4 and CAF, and why should I convert?

MP4 is a video container that holds compressed audio like AAC. CAF is Apple's professional audio container capable of storing high-resolution, uncompressed, or lossless audio. Converting to CAF is ideal for macOS audio workflows in Logic Pro or Final Cut Pro, as CAF supports advanced metadata, multichannel layouts, and higher bit depths than MP4 audio.

Does the MP4 to CAF conversion lose audio quality?

No. If you use passthrough mode, the original AAC frames are copied directly into the CAF container without re-encoding. If you choose ALAC or PCM, the audio is decoded losslessly then re-encoded, preserving sample rate, bit depth, and channel count. Compression artifacts already present in the MP4 will remain, but no additional quality loss is introduced.
