WMA preserves your audio at full quality, but the large file sizes make it impractical for sharing or mobile playback. Converting to OGG compresses the audio to a fraction of the size while maintaining quality that is virtually indistinguishable from the original at moderate bitrates.
WMA (Windows Media Audio, introduced in 1999) uses Lossy (modified DCT) or Lossless compression. OGG (Ogg Vorbis, introduced in 2000) uses Lossy (MDCT-based, psychoacoustic model) compression. WMA browser support: Limited (Edge on Windows only). OGG browser support: All modern browsers (Chrome, Firefox, Edge; no Safari).
Both WMA and OGG use lossy compression. Converting between two lossy formats involves decoding the WMA file and re-encoding it as OGG, which introduces an additional generation of compression. To minimize quality loss, use the highest practical quality setting for the OGG output.
Typical WMA file size: A 4-minute song at 192 kbps: ~5.5 MB. Typical OGG file size: A 4-minute song at quality 5 (~160 kbps): ~4.5 MB.
When converting between two lossy formats, use the highest practical bitrate for the output to minimize the quality impact of double compression. If possible, convert from the original lossless source instead of from a previously compressed file.
