YouTube-zu-MP4-Konverter

MP4 is the most universally compatible video format. It plays on virtually every device and platform — phones, computers, smart TVs, and media players. Unlike MKV or WebM, MP4 files work without any additional codecs.

Yes. Our downloader supports 1080p Full HD with audio included. We handle the video and audio stream merging automatically so you get a complete, ready-to-play MP4 file.

Simply open VidGrab in Safari on your iPhone, paste the YouTube link, choose your quality, and tap Download. The MP4 file will save to your device and can be played in the Photos app or any video player.

Yes, by default all our MP4 downloads include audio. We automatically fetch and merge the best audio stream with your chosen video quality. You can disable audio if you want a video-only file.

The maximum quality depends on the original upload. Most YouTube videos are available in up to 4K (2160p), and some go up to 8K. Our tool shows you all available quality options after you paste a link.

No, there is no file size limit. However, very long videos at 4K quality can produce large files (several GB). For most content, file sizes range from 50MB (360p) to 2GB (4K) depending on length and quality.

Our tool attempts to access age-restricted content, but some heavily restricted videos may not be downloadable. Most standard videos, including those with mild age restrictions, work without issues.

VidGrab offers native 4K support, no pop-up ads, no registration, and true audio-video merging. Many competitors limit resolution to 720p or 1080p, serve aggressive ads, or require sign-up for higher quality downloads.
