Frequently Asked Questions

Are files uploaded to a server?

No. All conversion is done entirely in your browser using the Web Audio API. Your files never leave your device.

What formats can I convert from?

Any audio format your browser can decode — typically MP3, WAV, OGG, M4A, AAC. Supported formats vary slightly by browser.

Will the audio quality change?

WAV output is lossless 16-bit PCM. For MP3 output, higher bitrate preserves more quality. Converting from a compressed format to another always involves some quality loss.
