Frequently asked questions
Which MP3 quality should I choose?
192 kbps sounds good for most music and speech. Choose 320 kbps if you want the best quality and don't mind larger files.
Can I convert audio from a YouTube link?
No. FileToaster only converts files on your own device and never downloads anything from the internet.
Are my audio files uploaded?
No. Decoding and encoding happen in your browser, on your device.
Does converting to MP3 lose quality?
MP3 is a lossy format, so a little detail is removed. At 192 kbps or higher, most people can't hear the difference.
