Frequently Asked Questions - WAV to MP3
How much does the size reduce when converting WAV to MP3?
Example: a 30 MB WAV (3 min song) converts to ~3 MB MP3. Typical 90% reduction. An album of 10 songs goes from 300 MB to 30 MB.
Is the quality loss noticeable?
For the average human ear, no. We use 128 kbps, which removes inaudible frequencies. Audiophiles may notice subtle differences, but for podcasts, casual music, and voice it's imperceptible.
When should I NOT convert WAV to MP3?
Don't convert if: 1) You need to edit audio professionally (better keep WAV), 2) You're a music producer and need maximum fidelity, 3) You'll convert the audio multiple times (each conversion loses quality).
Can I reconvert MP3 to WAV to recover quality?
No. Converting MP3 → WAV only increases file size, it doesn't recover lost quality. The resulting WAV still has the quality of the original MP3.
Why use PrivAudio instead of other converters?
Total privacy. Your WAV file (which could be original music, demos, private recordings) is never uploaded to any server. Everything is processed on your device.
Can I convert WAV to MP3 on my mobile?
Yes, PrivAudio works perfectly on iPhone, Android and any modern browser. No app installation required. Just open the web and convert.
