FAQ
Which MP3 bitrate should I pick?
96–128 kbps is fine for speech, 192–320 kbps for music.
Is the Audio Converter free?
Yes, completely free with no sign-up and no usage limits.
Are my files or text uploaded anywhere?
No. Everything runs right in your browser: your files and text are never uploaded, never stored by us and never seen by anyone but you.
Does it work on a phone?
Yes, but video processing on a phone is slower than on a computer. Use a computer for large files.
