FAQ

Frequently asked questions

Will the audio quality drop?

MP3 is a lossy format, so a little detail is discarded during conversion. At bitrates of 256 kbps and above, most listeners won't notice any difference.

How much smaller will the file be?

A WAV file usually shrinks to roughly a tenth of its size, depending on the bitrate you pick. That makes MP3 perfect for email and messaging apps.

Are my files uploaded anywhere?

No. Conversion happens locally in your browser by default. An optional server mode exists for very large files, but you have to choose it explicitly.

Can I set the bitrate myself?

Yes. You can pick a bitrate from 128 up to 320 kbps and decide for yourself whether smaller files or higher quality matters more to you.
