WAV to MP3 Converter
Compress bulky WAV recordings into portable MP3 files in your browser.
WAV files are uncompressed and huge, which is great for editing but impractical for sharing or storing. Converting to MP3 shrinks them by roughly 90% while staying perfectly listenable.
Pick a bitrate to balance size against quality — 192 kbps is a great default. Conversion runs entirely in your browser, so your recordings stay private.
