Frequently asked questions
Can I change bitrate, sample rate, or channels?
Yes. Open Advanced audio options to choose channels, sample rate, and bitrate where the selected output format supports them.
Which output format should I choose?
MP3 is best for compatibility, WAV is useful for editing, FLAC keeps lossless quality, and Opus is efficient for modern playback.
Are my audio files uploaded?
No. Conversion runs in your browser, so your files are not uploaded to a server.
Why did conversion fail?
The browser may run out of memory, the file may be unsupported, or the chosen settings may not work with the selected output format. Try a smaller file or another format.
