What is WAV?
Uncompressed audio format. Perfect quality with no data loss. Standard for music production and professional audio work.
What is MP3?
The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.
Why Convert WAV to MP3?
WAV files are huge. A 3-minute song in WAV format takes about 30MB. The same song as MP3 takes 3-5MB. That's a 90% size reduction. For sharing, streaming, or storing large music libraries, MP3 is the practical choice. Most listeners can't distinguish 320kbps MP3 from WAV in a blind test.
Frequently Asked Questions
How much smaller will my MP3 be compared to WAV?
About 10x smaller. A 50MB WAV file converts to roughly 5MB as MP3 at 320kbps. At 128kbps, it's even smaller — around 2MB.
What bitrate should I use?
320kbps for the best quality, 192kbps for a good balance of quality and size, 128kbps for voice recordings or podcasts where size matters more than fidelity.
Will I lose audio quality?
Yes, MP3 is a lossy format. But at 320kbps, the difference from WAV is nearly imperceptible to most listeners. For casual listening and sharing, it's more than enough.
Are my files uploaded to a server?
No. Conversion happens entirely in your browser. Your audio files never leave your device.
