About AIFF to CAF Conversion
Short answer: yes, you can convert AIFF to CAF online for free, and quality is well preserved with the right settings. Just upload your .aiff file to CocoConvert, pick CAF as the output, and click Convert. The whole process takes seconds.
Now for the details. AIFF is Apple's uncompressed audio format — equivalent to WAV in quality. CAF is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your AIFF file is decoded and re-encoded as CAF. Converting AIFF to CAF maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
