Should you convert AIFF to WMA?
A good trade for listening and sharing: WMA is a fraction of the size of AIFF, and at 192 kbps or more the difference is inaudible for most people. Keep the AIFF as your master if you’ll edit or convert again.
AIFF is uncompressed audio, Apple’s equivalent of WAV; WMA is the Windows Media audio format from the Windows XP era. Choose WMA only for an old Windows device; convert your WMA rips to MP3 or M4A to play them anywhere.

What changes when AIFF becomes WMA
From lossless to lossy
AIFF holds every sample; WMA keeps what the ear notices and discards the rest. Pick the bitrate by use: 128 kbps for speech, 192 to 256 kbps for music.
Who needs WMA
Choose WMA only for an old Windows device; convert your WMA rips to MP3 or M4A to play them anywhere.
A one-time engine download
AIFF is decoded by FFmpeg compiled to WebAssembly, a 31 MB download the first time. After that it is cached, and the conversion never leaves your device.
Expect a much smaller file
AIFF: About 10 MB a minute at CD quality. WMA: Similar to MP3. Shrinking the file is often the main reason to make this conversion.
This page is put together from our notes on each format, choosing only what is true of AIFF and WMA, so every pairing states the same facts the same way. How these pages are made.
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 AIFF. AIFF stores samples in the opposite byte order to WAV; tools that assume WAV turn it into loud static.
- About the WMA. WMA files bought from old online stores are often DRM-protected; no converter can open those.
- 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.
