Why WAV files are so large
WAV stores every sample uncompressed. CD-quality stereo, 16-bit at 44.1 kHz, uses 1,411 kbps, about 10 MB per minute. MP3 at 192 kbps throws away detail most people can't hear and uses about a seventh of that.
Keep WAV for mixing, mastering and archiving, where every bit counts. Use MP3 for sending demos, uploading to sites with size limits, and listening on phones.
| Length | WAV (16-bit, 44.1 kHz stereo) | MP3 at 192 kbps |
|---|---|---|
| 4-minute song | About 42 MB | About 6 MB |
| 30-minute recording | About 318 MB | About 43 MB |
24-bit or 48 kHz WAV files are larger still; the MP3 size stays the same.
Questions about this tool.
Does converting WAV to MP3 lose quality?
A little, because MP3 is lossy. At 192 kbps the difference is hard to hear for most listening. Keep the WAV if you'll edit the audio again.
Can I convert a WAV larger than 100 MB?
Yes, with Pro. Long WAV recordings pass 100 MB quickly, at about 10 MB per minute.
Can I convert MP3 back to WAV?
Yes, choose WAV as the output. It won't restore detail lost to MP3, but it gives you a format editors accept.
Are my recordings uploaded?
No. Conversion runs in your browser, which is why it's safe for unreleased music.
Prefer a desktop app?
The Mac and Windows app works offline and saves results beside your original. It includes 5 free conversions, then costs $1 once per computer, separate from Pro.
