Save YouTube videos as MP4 in seconds
MP4 is the universally-compatible container for H.264 video and AAC audio — it plays on every phone, tablet, TV, and video editor. yt2mp3.lol pulls the highest-quality MP4 streams YouTube serves, merges them with FFmpeg, and hands you a single file that's ready for offline viewing, archiving, or editing.
Available resolutions
We always select the best track that matches your chosen height. 360p and 720p are the safest bet for small phones and slow connections. 1080p is the sweet spot for laptops and TVs. 1440p and 2160p (4K) are exported when the original video was uploaded at those resolutions.
How to download YouTube as MP4
Copy the video URL from YouTube's share menu or your browser address bar, paste it into the converter, select MP4 and your preferred resolution, then click Convert. A three-minute 1080p clip typically takes under 10 seconds.
Shorts and live replays
Shorts export in their native vertical aspect ratio. Live stream replays (VODs) work once YouTube has finished processing them, usually within minutes of the stream ending.
