What is OGG?
Ogg container is an open media container from Xiph often carrying Vorbis or Opus audio (and sometimes video), created by Xiph.Org (2001). OGG is a patent-conscious open container popular in FOSS and some web audio. Convert to MP3/AAC when you need mainstream device reach.

OGG compression & quality
OGG compression: lossy (Vorbis typical). Lossy encoding discards some information to shrink files — re-saving repeatedly can accumulate artifacts. Typical size profile: Competitive with MP3; efficient for speech and music. Quality note: Vorbis often matches MP3 quality at lower bitrates
Quality: Vorbis often matches MP3 quality at lower bitrates
Typical size: Competitive with MP3; efficient for speech and music
Transparency & animation
OGG does not support an alpha channel. Convert to PNG, WebP, AVIF, or SVG when you need transparent backgrounds.
