Questions about audio converter
Which formats work in my browser?
MP3 and WAV work everywhere. M4A (AAC) and OGG (Opus) use your browser’s built-in encoders; for example, Firefox can’t currently create AAC. If a format isn’t available you’ll see a clear message, not a broken file.
Are my files uploaded?
No. Audio and video are processed in your browser with its built-in codecs, and are not sent to a server.
