How to convert WAV to MP3 in 3 steps

  1. Drop your WAV file — File stays on device, never uploaded. Works offline after first load.
  2. We auto-select MP3 — For wav-to-mp3, we pre-select MP3 output. You can change quality, resolution, rotate.
  3. Convert & download — Click Convert. Fast remux uses -c copy when possible (instant), otherwise H.264 + AAC re-encode.

Why private matters: Wedding videos, work recordings, voice memos — uploading leaks them. Here, ffmpeg.wasm runs locally. No server copy.

FAQ: WAV to MP3

Is WAV to MP3 private?

Yes. ffmpeg.wasm runs in your browser tab. No upload endpoint exists. Your file never leaves your computer.

Is it free? Watermark?

Free forever, no watermark, no account. Supported by ads after you click Accept.

Max file size?

Best under 500MB. Hard limit 1GB. For larger, use desktop Handbrake/Shutter Encoder.

Will quality drop?

If we can fast-remux (same codec, just changing container), no loss and instant. If we must re-encode (e.g., WAV→MP3 with different codec), we use CRF 23 (Balanced) — visually lossless for most.
