How much smaller is MP3 compared to WAV?

A lot — MP3 is typically 8–10× smaller than uncompressed WAV. A 50 MB WAV usually becomes a 5 MB MP3 at 320 kbps.

Will I hear a difference after converting WAV to MP3?

At 320 kbps the difference is inaudible to most listeners. MP3 is lossy, so for studio mastering keep WAV, but for listening and sharing MP3 is ideal.

Why convert WAV to MP3?

WAV files are huge and awkward to email or upload. MP3 plays on every device and music app, streams easily and takes a fraction of the space.

What bitrate should I pick when converting WAV to MP3?

Use 320 kbps for music — it is the highest MP3 allows and effectively transparent. For voice recordings, interviews and podcast episodes 128–192 kbps sounds just as clear and halves the file size again, which matters when a recorder has produced hours of WAV. If you are not sure, keep the default — storage is cheap, and a higher bitrate saves you from converting the same files again later.

Can I convert a long WAV recording, like a lecture or a DJ set?

Yes. Uploads up to 2 GB are accepted, and since uncompressed WAV takes roughly 10 MB per stereo minute, that is around three hours of audio in a single file. The MP3 of the same recording comes out small enough to email or post. The 2 GB ceiling applies per file, so several long recordings can go through in a single session.

Can I convert several WAV files to MP3 at once?

Yes. Add them all and click Convert — each WAV becomes its own MP3, so an album of masters or a folder full of recorder files shrinks to a shareable set in one pass.
