Frequently asked questions

Which bitrate should I choose?

Choose 128kbps to keep the file small, 192kbps for general use, or 256kbps if you need a higher bitrate.

Will the M4A sound exactly the same as the WAV?

No. The WAV audio is re-encoded with AAC, a lossy codec, so the quality may differ.

Is the original WAV's metadata kept?

No. The original metadata is not copied into the output.

Can I convert a WAV larger than 100 MiB?

No. Files over 100 MiB are rejected at the selection step.

Is my WAV file sent anywhere?

No. Your file never leaves your device. The conversion runs inside your browser and nothing is uploaded.
