Frequently asked

Why convert OGG to MP3? +

OGG (Vorbis/Opus) is efficient but not universally supported: plenty of players, car stereos, and devices reject it. MP3 is lossy and plays on nearly everything.

Are .opus files supported? +

Yes. Opus audio often lives in an .ogg or .opus container. This tool decodes both and re-encodes to MP3.

Why does it take a few seconds? +

Browsers have no native MP3 encoder, so the OGG audio is decoded and re-encoded with an in-browser LAME-based encoder. It all runs locally, so nothing is uploaded. Bigger files just take a little longer.
