Frequently asked questions
Is the MP4 uploaded to a server?
No. The video is read and converted by your own browser, so even large files stay on your device.
Which MP3 quality should I choose?
192 kbps sounds good for music and speech. Choose 320 kbps for the best quality or 128 kbps for smaller files.
Can I keep the original audio without converting?
Yes. Choose "Same as source" as the output format: the audio track is copied out of the video, usually as M4A, without any quality loss.
Is there a size limit?
Videos up to 2 GB work. Long videos take a little longer, because all the work happens on your device.
