WAV to MP3
Drop a WAV (or several). We compress it to MP3 with the bitrate you choose — fast, lossless decode, clean encode. Your bounce never gets uploaded.

or click to pick. AIFF supported too.
How it works
Your browser already decodes audio. We pair that with a tiny encoder (pure JavaScript for MP3, or a slim WebAssembly codec for less common formats) and put it behind a drop target. The whole pipeline runs in your tab. The first conversion may take a moment to load the codec; after that it's instant and cached.
Why convert WAV files
WAV files are great for some workflows and frustrating for others. MP3 fixes the common compatibility headaches without losing what matters about your audio.

Can I convert multiple files?
Yes, drop several at once and you'll get a zip back.
How big can the file be?
Around 500 MB on a typical laptop. Past 1 GB the browser starts running out of memory.
