4K YouTube Video Downloader
Save YouTube videos in 4K Ultra HD (2160p) or 1440p, with sound, exactly as YouTube streams them.
Paste the link of a video published in 4K, open the Video tab and choose 2160p (4K) or 1440p. The video is saved as YouTube streams it, never re-encoded, with its sound added, and every option shows its file size first. 4K files are large, about 1 GB for 10 minutes, so they suit 4K TVs, monitors and video editing more than phones.
Real 2160p, not upscaled
You get YouTube's own 4K stream, copied without re-encoding, so every detail and the original frame rate stay as uploaded.
4K with sound
YouTube sends 4K picture and sound separately. They are joined while you download, with YouTube's original AAC audio.
Size shown before you download
4K is big: a 10-minute video is typically about 1 GB and an hour about 6 GB. Each quality lists its real size first.
Made for big screens
4K pays off on 4K TVs, monitors and in video editing. On a phone, 1080p looks almost the same at a fifth of the size.
4K Shorts too
Vertical videos are measured by their shorter side, so a 2160 × 3840 Short is offered as 4K.
Efficient AV1 files
1440p and 4K come in the AV1 format, which keeps 4K files smaller. Recent devices play it; for older ones, use VLC.

Choose 4K (2160p) for a 4K TV or monitor. 1440p is a good middle ground for 1440p monitors and large laptops: less than half the size of 4K and still sharper than 1080p.
4K and 1440p downloads use the AV1 format. On Windows, install Microsoft's free AV1 Video Extension or use VLC; recent smart TVs, phones and computers play AV1. If an older device still refuses, download 1080p, which uses H.264.
Yes. Copy the MP4 to a USB drive and plug it into the TV, or play it from a computer connected to the TV. The TV must support 4K and AV1; if it does not, use 1080p.
A 4K file is about five times the size of the same video in 1080p, and its picture and sound are joined while you download. Long 4K videos can take a few minutes to prepare and save.
