Frequently asked questions
Can I extract MP3 from a video?
Yes. Add an MP4, MOV or WebM video and choose MP3; the video's sound is saved as MP3.
Which quality should I choose?
For music, 192–256 kbps MP3 is a good balance. For speech, 128 kbps mono is enough; choose lossless WAV for editing.
How many files can I convert at once?
There is no fixed limit; files are processed one after another and the limit depends on your device's memory.
Are my files uploaded to a server?
No. All conversion happens in your browser; files are never sent anywhere.
