About Audio Converter
Convert audio files to MP3 or WAV right in your browser — drop in one or several files, pick a bitrate for MP3, and download the results, or grab them all at once as a ZIP. Decoding and encoding both happen on your device, so nothing is uploaded to a server. Handy for converting a WAV recording down to a compact MP3, or turning any audio your browser can play into an MP3 or WAV file.
- Convert to MP3 (with bitrate control) or lossless WAV
- Batch-convert multiple files and download as a ZIP
- Runs entirely on-device — no upload required
Frequently asked questions
Which audio formats can I convert from?
Anything your browser can decode — MP3, WAV, OGG, M4A/AAC and FLAC in most modern browsers. If a file fails to decode, try a different browser.
Is any audio uploaded to a server?
No. Decoding and encoding both run in your browser using the Web Audio API — your files never leave your device.
