Frequently Asked Questions
Why convert AIFF to Opus?
AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and is best for Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. Opus (Opus Interactive Audio Codec) uses lossy compressed encoding and excels at voice-over-IP, real-time communication, and streaming at very low bitrates with excellent quality. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
What bitrate should I use?
64-128 kbps is recommended for music. 32-64 kbps works well for speech. Higher bitrates preserve more detail but produce larger files.
Does Opus support all sample rates?
Opus supports 8kHz to 48kHz. AIFF files at higher sample rates (96kHz, 192kHz) are resampled to 48kHz maximum during conversion.
What browsers support Opus?
All modern browsers support Opus natively in WebM containers. For standalone .opus files, most media players (VLC, foobar2000) support them.
Is AIFF to OPUS conversion done locally?
Yes. All conversion runs in your browser using FFmpeg WASM. No audio files are uploaded.
