Should you convert FLAC to AIFF?
A lossless move: FLAC and AIFF both keep every sample, so the sound is identical and you can convert back at any time.
FLAC is lossless audio at roughly half the size of WAV; AIFF is uncompressed audio, Apple’s equivalent of WAV. Use AIFF for editing in Mac audio software, or when a Mac workflow asks for it.

Who needs AIFF
Use AIFF for editing in Mac audio software, or when a Mac workflow asks for it.
Expect a larger file
AIFF generally takes more room than FLAC. If the file has to fit an upload limit, check the size once it’s converted. FLAC: About 5–7 MB a minute for music. AIFF: About 10 MB a minute at CD quality.

Why it doesn’t upload
Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.
How to check for yourselfWorth knowing
- About the FLAC. FLAC made from an MP3 is lossless only in name: it perfectly preserves an already lossy recording, at five times the size.
- About the AIFF. AIFF stores samples in the opposite byte order to WAV; tools that assume WAV turn it into loud static.
- MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.
