How it works
Add WAV files
Drop in one WAV file or a whole batch - or click to choose them.
Check the format
MP3 is already selected at 192 kbps - change it if you like.
Convert & save
Everything is converted on your device - save each file, or all of them at once.
How to convert WAV to MP3 online
WAV is uncompressed - perfect for recording and editing, but a 4-minute song is about 40 MB. As a 192 kbps MP3 it's under 6 MB and sounds the same to nearly everyone.
Add your WAV files
Drop them on the box above or click to choose. Several at once is fine.
Choose the quality
MP3 is already picked. For MP3, 192 kbps suits most music, 320 kbps is the best, 128 kbps is smallest.
Convert
Press Convert. Each file shows a tick and its new size when it's done.
Save
Save files one by one, or Save all - allow multiple downloads once if your browser asks.
Frequently asked questions
Which bitrate should I choose?
192 kbps is the sweet spot for music. 320 kbps is the best MP3 can do; 128 kbps is fine for speech and podcasts.
How much smaller will my files be?
Around 7 times smaller at 192 kbps and about 4.5 times at 320 kbps, compared with a CD-quality WAV.
Are my WAV files uploaded?
No - they're converted on your computer, so even huge files are fine and nothing leaves your device.
Can I convert 24-bit or 32-bit WAV?
Yes. Any WAV your browser can play converts - 16, 24 or 32-bit, mono or stereo.
Why does Save all ask for permission?
Browsers protect you from sites that download many files at once. Allow it once for swarasound.com and the rest save automatically.
