Converting OGG to MP3 trades slightly better compression for universal device support. Vorbis is a fine codec, but MP3 is what every car stereo, dash cam, and legacy media player actually supports without extra codecs.

Both formats are lossy, so transcoding compounds the loss slightly. Matching or exceeding the OGG's bitrate in the MP3 minimizes audible artifacts. The original source would always produce a better MP3. Use the OGG only when the source isn't available.
MP3 is the most universally supported audio format in existence. Every device, every app, every platform handles it.
OGG Vorbis is a royalty-free lossy codec developed by Xiph.Org. At comparable bitrates it sounds cleaner than MP3, especially at 96 kbps and below, and it's the audio format used by Spotify's streams, most modern games, and open-source projects that want to avoid patent encumbrances.
MP3 is the most widely supported lossy audio format. Encoded in 1993 and still the default on countless devices, it trades some fidelity for dramatically smaller files. At 192 kbps most listeners cannot distinguish it from the source. Anything that plays audio will play MP3.
Compatibility. OGG has better compression efficiency, but MP3 plays on devices OGG can't touch: iPhones, older car stereos, certain Bluetooth speakers. You're trading audio quality for reach.
At least match the OGG's bitrate; 192 kbps is a good default. Going higher (256 or 320 kbps) can't undo the OGG's existing lossy compression but can prevent adding further MP3 artifacts.

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
