Download YouTube videos in 4K
When a video was uploaded in Ultra HD, you can keep it that way: 2160p or 1440p MP4, bit-for-bit as YouTube stores it.

About this tool
Plenty of download tools quietly cap everything at 1080p. Here the quality list reflects what the upload actually contains, so 1440p (often called 2K) and 2160p (4K) show up whenever YouTube has them. The stream is handed over without re-encoding — no softening, no artefacts added.
Be prepared for big files: a 4K video weighs about four to six times as much as the same clip in 1080p, and ten minutes can easily pass 1 GB. That is why anything above 1080p is capped at 45 minutes in length. Longer videos are still available at 1080p, up to 2 hours.
How it works
-
1
Find a video with 2160p
Open the quality menu on YouTube; if “2160p” is listed, the upload is genuinely 4K.
-
2
Paste the link here
The 2160p and 1440p options appear alongside the others, each with an estimated size.
-
3
Choose 2160p and download
Click Download next to it. Ultra HD files are large, so give the download a bit longer.
What you get
Real Ultra HD
Genuine 2160p from the source — never a 1080p file stretched to look like 4K.
Smooth motion kept
Videos uploaded at 50 or 60 fps keep their full frame rate, in 1440p as well as 4K.
Know the size first
An estimate sits next to every quality so you can plan your storage before you click.
No cost, no watermark
Nothing to sign up for and nothing stamped on the video. Files vanish from the server after 15 minutes.
Questions about this tool
The 4K option is missing. What happened?
Either the video was never uploaded in 4K or YouTube is still processing the higher resolutions. Only what the source really contains can be offered.
Can my phone or TV play the 4K file?
YouTube encodes 4K with VP9 or AV1. Anything reasonably recent — phones, laptops, smart TVs — handles it; some older media players do not.
How much storage will a 4K video take?
Expect roughly 100–200 MB for each minute, depending on how much movement the footage has. The exact figure is shown beside the option.
How long can a 4K video be?
Up to 45 minutes for 1440p and 2160p. At 1080p and below the limit rises to 2 hours.
