Questions

Is YouTube to MP4 free?

Yes, up to 1080p for 67 downloads a month. 1440p, 4K and 8K need a Pro pass.

Why is my 4K download not an MP4?

YouTube serves 4K and 8K mostly as VP9 or AV1, which normally come as WebM or MKV. Choose MP4 and PurffleGrab picks an MP4-friendly stream or remuxes it, so it plays on any device.

Will the MP4 have sound?

Yes. YouTube stores HD video and audio separately; PurffleGrab downloads both and joins them with the built-in FFmpeg.

Can I download only part of a video?

Yes. Set a start and end time, or pick chapters, before you download.
