Convert OGG to MP3
OGG Vorbis is technically the better format and almost nothing supports it. MP3 is the reverse.

The converter could not start.
The engine files are missing from — copy ffmpeg-core.js and ffmpeg-core.wasm there.
Almost always a mismatched build: the worker is an ES module, so the core has to be the esm one too. Copy ffmpeg-core.js and .wasm from @ffmpeg/core/dist/esm/, not dist/umd/.
not in this build of the converter, so it is not offered.
What you lose
A second lossy compression, and OGG at a given bitrate is usually a little better than MP3 at the same one — so match or exceed the source bitrate if you can.
What you do not gain
Compatibility, which is the entire reason anybody does this. The audio does not improve.
What it does to the size
Approximate, for stereo audio at the settings this tool uses by default. The real figure moves with the material — silence and speech compress far better than a full mix.
When this is the right conversion
A game, a Wikipedia clip or an open-source project handed you an OGG and the thing you want to play it on has never heard of the format.
