How to convert audio online

01

Add your files

Drop in one or many audio files. They're decoded on your device using the Web Audio API — nothing is sent to a server.

02

Pick a format

Choose MP3 with your preferred bitrate, or lossless WAV. The same setting applies to every file in the list.

03

Convert & download

Hit convert and watch each file's progress. Download them one by one, or grab them all at once.

Which formats can I convert?

Input can be anything your browser decodes — MP3, WAV, M4A/AAC, OGG and usually FLAC. Output is MP3 or WAV, the two formats that play everywhere.

Are my files uploaded to a server?

No. Conversion happens entirely in your browser, so your audio never leaves your device — and it's faster because there's no upload or download wait.

What bitrate should I choose for MP3?

192 kbps is a good balance of quality and size for most music. Use 320 kbps for the best quality, or 128 kbps for the smallest files, like voice recordings.

Can I convert many files at once?

Yes. Add as many as you like; they convert one after another so your browser stays responsive, and you can download them individually or together.
