Batch Settings
Quality reduction ahead
AIFF is uncompressed, meaning every bit of data is preserved. WEBM uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your AIFF file may contain ID3v2, AIFF chunks metadata. WEBM has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
WEBM lossy compression can produce blockiness (VP8), blurring (VP9/AV1). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
