Verdict: MP3 wins for listening and sharing — around a tenth of the size with quality most ears cannot distinguish from the original. WAV wins for recording and editing — uncompressed and bit-perfect with no generation loss. Listen and share as MP3; record and master as WAV.
| Criterion | MP3 | WAV |
|---|---|---|
| Compression | Lossy — roughly 10x smaller than WAV | Uncompressed PCM — full size |
| Sound quality | Transparent at 192 kbps and above | Bit-perfect original |
| Editing and re-saving | Generation loss on every re-encode | Re-save and re-edit without any loss |
| Compatibility | Plays on literally everything | Broad support, but files are huge |
| Streaming and sharing | The practical standard | Too big to stream or message casually |
| Best for | Music libraries, podcasts, sharing | Recording, mastering, samples |

At 192–320 kbps, controlled tests show most listeners cannot reliably tell them apart on normal equipment. Differences appear mainly after heavy editing or on revealing studio gear.
192 kbps is transparent for most material; 256–320 kbps for critical music. For speech-only podcasts, 96–128 kbps mono sounds fine at half the size.
No — the discarded detail is gone forever, and the WAV just wastes space. Convert WAV to MP3 for delivery, never MP3 to WAV for quality.
Yes — the linked converters process audio locally in your browser, so recordings and masters never leave your device.
