Convert WAV files

Your audio never leaves your device. We use WebAssembly to process everything locally.
No File Limits
Convert files of any size without restrictions. Perfect for podcasts and long recordings.
Batch Processing

Works Offline
Once loaded, the converter can function without an internet connection.
100% Client-Side Conversion
Most online converters require uploading huge WAV files to a remote server — slow, risky, and often paid. Our tool eliminates this bottleneck entirely by running the lamejs MP3 encoder directly in your browser via a Web Worker.
Which MP3 Bitrate Should You Choose?
A 4-minute song as CD-quality WAV is ~40 MB. The same song as a 320 kbps MP3 is ~9.4 MB — saving 77% of storage while sounding virtually identical to 95%+ of listeners in blind tests.
