Generation loss — quality may degrade
OGG uses lossy compression, and so does WEBM. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your OGG file may contain Vorbis comments 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.
