MP3 quality, from 128 kbps to 320 kbps
128 kbps keeps files tiny and sounds fine for voice. 192 kbps is the sweet spot for music on phones and earbuds. 320 kbps is the highest standard MP3 quality — bigger files, best sound. The result can never be better than your original file, so a clean source at 192 kbps sounds great.
What you can convert
MP4, M4A, WAV, WEBM, OGG and MP3 — anything your browser can play, it can turn into an MP3. Music videos, voice recordings, podcasts, lectures: if it has audio, you get an MP3 out of it.
