About AIFF to WebM Conversion
AIFF is Apple's uncompressed PCM format, while WebM is Google's open multimedia container built for the web. WebM pairs VP8/VP9 video with Vorbis or Opus audio. Converting AIFF to WebM encodes the pristine PCM audio to Opus — the most efficient audio codec available — producing files optimized for web delivery. Opus at 128 kbps from uncompressed AIFF source delivers quality that matches AAC at 192 kbps.
Why Convert AIFF to WebM?
WebM with Opus audio is the most bandwidth-efficient format for web audio delivery. Encoding from uncompressed AIFF produces the best possible Opus output — first-generation compression from pristine source material. For web applications, Progressive Web Apps, and browser-based audio players, WebM/Opus offers the best quality-per-byte of any audio format available.
