FAQ
How much smaller will the MP3 be?
Typically 5–15× smaller than the original WAV. A 50 MB WAV file may compress to 3–8 MB MP3 at 128–192 kbps.
Does converting WAV to MP3 lose quality?
Yes. MP3 is a lossy format. Higher bitrates (192–320 kbps) preserve more quality but produce larger files. 192 kbps is transparent for most listeners.
Can I convert stereo WAV to mono MP3?
The tool preserves the original channel layout by default. Mono/stereo conversion is not currently available in this tool.
