AIFF vs Opus at a glance
AIFF is Apple's uncompressed audio format — the Mac equivalent of WAV, lossless and studio-standard but with much less support outside professional audio software. Opus is the modern voice and streaming codec behind WhatsApp voice notes and Discord calls — excellent quality at tiny file sizes, but not widely supported by standalone music players or older devices.

AIFF to Opus — frequently asked questions
Is this AIFF to Opus converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to Opus?
Opus uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Audio conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
