About this tool
Audio format conversion is usually driven by a compatibility problem — a FLAC file that a phone player will not open, a WAV too large to share, an M4A that an old car stereo does not recognise. The right output format is whichever one the destination device or application accepts, balanced against the acceptable file size and quality.
When converting from any lossy format to any other, both codecs are applied to the same underlying audio. An MP3 at 128 kbps converted to OGG at 128 kbps will sound slightly worse than the original MP3, because the OGG encoder is working from an already-compressed signal. This is unavoidable. For that reason the default bitrate here is set slightly higher than the strict minimum — 192 kbps rather than 128 kbps — to leave headroom for the generation loss.
