Converting MP3 to OGG Vorbis re-encodes the audio through a different lossy codec. Vorbis tends to sound slightly cleaner than MP3 at the same bitrate, especially below 128 kbps, and is royalty-free, which is why it's the native format in Unity, Godot, and many Linux distributions.

This is a transcode between two lossy codecs, so quality will drop by a small but measurable amount. To minimize the loss, pick an OGG bitrate at least as high as the source MP3. You cannot recover detail the MP3 discarded, only avoid piling more loss on top.
OGG plays on Windows (with codec pack or VLC), macOS (VLC, modern browsers), Linux (native), Android (native since 2.3), and all modern browsers via HTML5 audio. iOS Safari does not play OGG natively, which is the main limitation.
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.
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.
Generally yes at the same bitrate. Vorbis was designed after MP3 and handles things like cymbals and reverb tails with fewer artifacts. The difference is most audible below 128 kbps and shrinks as bitrate climbs.
A small amount. You're transcoding lossy to lossy, so each encode adds some artifacts. Keep the OGG bitrate at or above the MP3's bitrate to minimize the loss.

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.
