Question 1

What audio formats can I convert to WAV?

Accepted Answer

You can convert MP3, OGG, AAC, M4A, FLAC, WebM, OPUS and any other format your browser can decode into a WAV file. Output is 16-bit or 24-bit PCM WAV.

Question 2

Is my audio uploaded to a server?

Accepted Answer

No. All decoding and WAV encoding happens entirely in your browser using the Web Audio API. Your files never leave your device.

Question 3

Can I choose the sample rate and bit depth?

Accepted Answer

Yes. Pick from 8000 Hz to 48000 Hz sample rate, and 16-bit or 24-bit depth. Higher rates give better quality but larger files.

Question 4

Why is WAV so much bigger than MP3?

Accepted Answer

WAV is uncompressed PCM audio — every sample is stored in full. MP3 uses lossy compression that throws away inaudible data, so it can be 10x smaller at near-CD quality.
