Converting between MP3 and OGG changes the codec used for compression. OGG Vorbis offers superior quality per bit compared to MP3 and is royalty-free.
MP3 (MPEG Audio Layer III, introduced in 1993) uses Lossy (psychoacoustic model + MDCT) compression. OGG (Ogg Vorbis, introduced in 2000) uses Lossy (MDCT-based, psychoacoustic model) compression. MP3 browser support: Universal. OGG browser support: All modern browsers (Chrome, Firefox, Edge; no Safari).
Both MP3 and OGG use lossy compression. Converting between two lossy formats involves decoding the MP3 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 MP3 file size: A 4-minute song at 192 kbps: ~5.5 MB; at 320 kbps: ~9.2 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.
