How to Download YouTube Videos in 4K and 1080p (Free)
Quick answer (TL;DR): To download a YouTube video in 4K or 1080p, paste the URL into The YouTube Tool's downloader and pick the 2160p (4K) or 1080p option. It is free, with no signup or watermark. The one rule: you can only get 4K if the creator actually uploaded the video in 4K. No tool can add detail that was never there.
Most "4K YouTube downloader" pages bury the one thing that decides whether you get a real 4K file. So here it is up front: a downloader cannot create resolution. If the source video was published in 1080p, the highest honest download is 1080p, and any tool promising "4K" is upscaling, which inflates the file size without adding a single pixel of real detail. This guide shows how to actually pull the highest available quality, how to tell what a video supports before you download, and the two technical traps that quietly ruin "HD" downloads.
Can you really download YouTube videos in 4K?
Only when the video exists in 4K to begin with. YouTube stores a separate file for each resolution the creator's upload supports, from 144p up to 4320p (8K). When you download, you are choosing one of those existing files. So the real questions are: did the creator upload in 4K, and does your tool give you that top file intact?
You can check before downloading. On the YouTube video, open the quality menu (the gear icon). If you see 2160p, the video has a 4K source and a 4K download is possible. If the list tops out at 1080p or 1440p, that is your ceiling, and that is the best any downloader can honestly give you.
How do you download a YouTube video in 4K for free?
- Confirm the video offers 2160p in YouTube's quality menu (gear icon). No 2160p, no 4K download.
- Copy the video URL and paste it into the free downloader.
- Select 2160p (4K), or 1080p if that is the source ceiling, and save the MP4.
The same flow covers 1440p and 1080p HD, so a "YouTube 1080p downloader" and a "4K downloader" are the same tool, just a different quality pick.

The same toolkit handles YouTube Shorts too.
Why do some videos only download in 1080p or lower?
Three reasons, and knowing them saves a lot of confusion:
- The creator never uploaded in 4K. Most videos before the mid-2010s, and plenty since, max out at 1080p. There is no 4K version to fetch.
- You hit the 720p progressive wall. YouTube serves a single combined video-plus-audio file only up to 720p. Everything above that (1080p, 1440p, 4K) is delivered as separate video and audio streams that a downloader must merge back together. Tools that skip the merge step silently cap you at 720p or hand you a higher-resolution file with no sound. A proper downloader merges them, which is why our downloader returns 1080p and 4K with audio intact.
- The codec tripped up the tool. YouTube encodes 4K in modern codecs like VP9 and AV1, not the older H.264 that everything plays natively. We cover what that means next.
What about file size and codecs at 4K?
Two practical things to expect.
File size scales fast. As a rough guide, expect very roughly 1 to 2 GB per hour at 4K, around 400 to 600 MB per hour at 1080p, and around 200 MB per hour at 720p. Actual size swings with the video's length, frame rate, and how much motion it contains, but the gap between 1080p and 4K is large enough that you should download 4K only when you will actually use it (large screens, editing, archiving).
4K usually means VP9 or AV1, not H.264. YouTube delivers 4K in efficient modern codecs. They look great and keep files smaller, but very old devices or some basic editors cannot play VP9 or AV1 directly. If you need maximum compatibility, either pick a 1080p H.264 download (which plays literally everywhere) or convert the 4K file afterward. If your goal is a guaranteed-compatible MP4, read how to convert YouTube to MP4.
| Resolution | Pixels | Rough size per hour | Best for |
|---|---|---|---|
| 720p HD | 1280x720 | ~200 MB | Quick saves, social clips |
| 1080p Full HD | 1920x1080 | ~400-600 MB | Editing, most archiving, max compatibility |
| 1440p (2K) | 2560x1440 | ~1 GB | Sharp playback on large monitors |
| 2160p (4K) | 3840x2160 | ~1-2 GB | Big screens, professional editing, future-proofing |
Are there real 4K and 8K downloads, or is "8K" a gimmick?
8K is real on YouTube, but rare. A handful of videos are uploaded in 4320p, and tools like the desktop 4K Video Downloader Plus or the open-source yt-dlp can fetch them. For the other 99% of videos, the meaningful ceiling is 4K, and most often it is 1080p. Treat any browser tool's "8K" badge with suspicion unless the source video genuinely offers 4320p in YouTube's quality menu, because for an ordinary 1080p upload the label is meaningless.
FAQ
How do I download a YouTube video in 4K for free? Confirm the video offers 2160p in YouTube's quality menu, then paste the URL into a free downloader and select 2160p. The 4K MP4 saves with no signup or watermark.
Why can't I download a video in 4K? Because the creator did not upload it in 4K. A downloader can only retrieve resolutions that already exist for the video. If YouTube's quality menu stops at 1080p, that is the highest you can get.
Does a 1080p or 4K download include sound? It should, but only if the tool merges streams. YouTube serves video and audio separately above 720p, so a downloader has to combine them. A quality tool does this automatically; weaker ones leave you with a silent file.
Is 4K download quality really better than 1080p? Only on a screen large enough to show it and when the source is true 4K. On a phone, the difference is invisible and the file is several times larger. Pick 1080p unless you specifically need 4K.
What codec are 4K YouTube downloads in? Usually VP9 or AV1, which YouTube uses for high resolutions. They are efficient and high quality but may not play on very old devices, where a 1080p H.264 file or a converted MP4 is the safer choice.
