Frequently asked questions

How do I convert audio to MP3 for free?
Drop your file in, choose MP3 as the output format, and download the result. There is no charge, no sign-up and no watermark. The conversion happens on your own device, so even large files convert without an upload.
Which formats can I convert between?
You can convert to and from MP3, WAV, OGG and M4A, and the tool reads most other common audio formats your browser supports as input. Pick the target that fits where the file is going: MP3 for broad compatibility, WAV for lossless quality.
Why does a large file take a while?
Because the conversion runs on your device rather than a server, the speed depends on your computer and the file size. Short clips convert in seconds; a long, high-quality file takes longer. Nothing is uploaded, which is the trade-off for that privacy.
Is it really free, and is there a watermark?
It is free and there is no watermark, no sign-up and no email wall. You get the full-quality file straight back, with nothing added and nothing held behind a paywall.
Is my file uploaded to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
