Frequently asked questions
How do I convert an audio file?
Drop your file onto the converter, choose MP3 or WAV as the output, and it is converted right in your browser. A Download button appears when it is done — no install, no account, no upload.
Which formats can I convert?
You can drop in MP3, WAV, M4A, FLAC, and the audio from MP4 or MOV video, and convert it to MP3 (320, 192, or 128 kbps) or WAV.
Is my file uploaded?
No — conversion happens entirely in your browser. Your file never leaves your device.
Is it really free?
Yes — the converter is genuinely free, with no sign-up and no watermark. It runs on your own device, so there is no server cost to pass on.
How big a file can I convert?
The converter is built for songs and clips up to 30 minutes or 500 MB. That covers most music and recordings; very long videos are too large to process in the browser.
MP3 encoding uses lamejs (LGPL-2.1).
