How the two formats differ on the things that change your result.

This is a transcode, not a copy: Vorbis is decoded and then re-encoded as MP3, and every re-encode costs a little quality. If the source was encoded at a low bitrate, encode the MP3 file near 320 kbps so the second pass is not the bottleneck.
OGG can carry sample rates up to 192 kHz, but MP3 tops out at 48 kHz. High-resolution sources are resampled down on the way through.
Multichannel sources need care: MP3 handles at most 2 channels where OGG allows 8, so anything wider is downmixed.
This conversion buys reach. Unlike OGG, MP3 is natively supported on web browsers, Windows, macOS, iOS, and smart TVs, which is usually the reason people convert in this direction.
This conversion moves the file toward a different purpose: OGG suits game audio, open-source projects, web delivery, whereas MP3 is chosen for music libraries, podcasts, sharing with anyone.
Converting OGG to MP3 means moving audio out of the Ogg container, introduced in 2000, and into MPEG-1/2 Audio Layer III, which arrived in 1993. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by Xiph.Org Foundation in 2000, OGG carries lossy-compressed audio (Vorbis). That sets the upper bound on what any conversion can preserve.
MP3 was introduced by Fraunhofer IIS / MPEG in 1993. It holds lossy-compressed audio (MP3) and plays natively on web browsers, Windows, macOS, iOS, Android, and smart TVs.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
