Questions
How much smaller will the MP3 be?
CD-quality stereo WAV uses about 10 MB per minute. A 192 kbps MP3 uses about 1.4 MB per minute.
Will I hear a difference?
At 192 kbps or higher most listeners can't tell on everyday speakers and headphones. Keep the WAV if you'll edit or master the audio later.
Is my audio uploaded to a server?
No. The tool runs in your browser and works on your audio directly on your device. Nothing is sent to us or anyone else, which is why it also keeps working if your connection drops after the page loads.
