About FLAC to AIFF Conversion
Short answer: yes, you can convert FLAC to AIFF online for free, and quality is well preserved with the right settings. Just upload your .flac file to CocoConvert, pick AIFF as the output, and click Convert. The whole process takes seconds.
Now for the details. FLAC is lossless audio compression — bit-for-bit identical to the original at roughly 50-70% of WAV size. AIFF is Apple's uncompressed audio format — equivalent to WAV in quality. Converting between these two formats lets you convert between formats quickly.
Full Name: FLAC uses Free Lossless Audio Codec, while AIFF uses Audio Interchange File Format. Compression: FLAC uses Lossless, while AIFF uses None (uncompressed). Typical File Size: FLAC uses 5–7 MB per minute (50–70% of WAV), while AIFF uses 10 MB per minute at 44.1 kHz/16-bit stereo.
Your FLAC file is decoded and re-encoded as AIFF. Converting FLAC to AIFF maintains high quality with CocoConvert's optimised encoder settings.
Common misconception: ""AIFF will be smaller than my FLAC file"" — in reality, aiff uses no compression, so the output file is often larger than a lossy flac. if you need a small file, aiff may not be the right choice.
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.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
