MP3 → OGG (Opus), in your browser
For OGG-only pipelines. Stated upfront: from MP3 source, this trades a little quality for a lot of compatibility.

When a game engine, mod toolkit or open-format pipeline takes OGG and nothing else, the MP3 in hand has to change shape. This page re-encodes it to Opus locally. Two lossy codecs in a row leave marks, so the guidance is simple: keep output at 128 kbps or above, use the best MP3 you have, and if the true source exists in lossless form anywhere, start from that instead. For voice and effects, the result is routinely fine.
Questions
Is MP3 to OGG ever a good idea?
When the destination accepts nothing else, yes. The alternative, no working audio, is worse than a marginal quality cost.
How do I minimise the damage?
Highest sensible output bitrate, cleanest source MP3, no further conversions afterward. Each additional generation compounds.
Voice content too?
Voice tolerates re-encoding well; Opus is excellent at speech even at low bitrates.
Anything leave my machine?
No. Everything runs client-side.
