Convert WAV to MP3 — Free Online
Convert WAV audio files to MP3 format instantly. Choose bitrate from 64 to 320 kbps. Free, private, runs in your browser.
WAV files sound great but are massive — a 3-minute song can be 30MB. Converting to MP3 shrinks files by 90% while keeping audio quality that's indistinguishable to most listeners. Choose 192+ kbps for near-CD quality.

How It Works
This tool uses FFmpeg compiled to WebAssembly to perform professional-grade audio conversion entirely in your browser. The FFmpeg engine loads once (~30MB) and stays cached for instant conversions on return visits.
Select your target format (MP3, WAV, OGG, FLAC, AAC, M4A), optionally adjust bitrate and sample rate, then convert. The tool handles codec transcoding, metadata preservation, and format-specific optimizations automatically.
