How do I convert MP3 to CAF using this tool?

Upload your MP3 file, select 'CAF' as the output format, choose your preferred codec (e.g., PCM 16-bit for Apple apps), and click Convert. Once processing completes, download your CAF file directly. You can also adjust sample rate and bit depth before conversion.

Why should I convert MP3 to CAF instead of keeping it as MP3?

MP3 is lossy and compressed, while CAF is Apple's container that can hold uncompressed PCM or other codecs. CAF is ideal for iOS/macOS development, Core Audio, low-latency playback, and scenarios where you need sample-accurate timing or more flexibility in editing. It also preserves metadata better than MP3 in some cases.

What happens to the audio quality and metadata during MP3 to CAF conversion?

Because MP3 is lossy, the original source data is already reduced. Our converter decodes MP3 fully and stores it in CAF—if you choose uncompressed PCM, there is no further generation loss. Metadata such as artist, title, and album are copied over; sample rate and channel count remain the same unless you manually change them. However, you cannot recover frequencies lost during MP3 encoding.
