Why is YouTube to MP4 better than screen recording?

Downloading as MP4 gives you the original video quality (up to 1080p Full HD) with proper H.264 encoding, while screen recording captures lower quality with potential frame drops. MP4 downloads are also faster and produce smaller, better-quality files.

What is H.264 and why does it matter for MP4 downloads?

To extract audio from YouTube, paste the video URL into MP3Extra and select the MP3 format option. This downloads only the audio track without the video, saving space and data. Perfect for music, podcasts, and lectures.

Is MP3Extra better than browser extensions for downloading YouTube?

Can I download age-restricted or private YouTube videos?

Age-restricted videos may not be downloadable. Private videos and unlisted videos that require login cannot be downloaded. MP3Extra works best with public YouTube videos that anyone can view without logging in.

What should I do if the download is slow?

If your download is slow, try selecting a lower quality (360p instead of 1080p) for smaller file sizes. Check your internet connection speed. You can also try refreshing the page and starting the download again. For audio, MP3 downloads are much faster than video.
