Frequently asked questions
Why can't I convert to MP3?
MP3 encoding requires a proprietary codec that browsers don't include. WAV, OGG and WebM cover editing and web use — use an external tool if you specifically need MP3.
Is WAV the best quality option?
Yes — WAV is lossless PCM, identical to the source audio. OGG and WebM use the high-quality Opus codec, which is smaller but lossy.
Which files can I convert from?
Anything your browser can decode: MP3, WAV, OGG, M4A, AAC and WebM. Your browser version decides the exact set.
Are my files uploaded anywhere?
No — the entire conversion runs in your browser and your audio never leaves your device.
