Download YouTube in 4K: Best Tools in 2026

Want to download YouTube in 4K to enjoy the sharpest image quality on your UHD display? With 4K monitors and TVs now mainstream, downloading at 2160p resolution has become a common need — but also a technical challenge. Not all tools handle 4K properly, and the resulting files are significantly larger than their 1080p counterparts.

This guide covers the best tools for downloading YouTube videos in 4K in 2026, compares video codecs (H.264, VP9, AV1), explains hardware requirements, and helps you pick the right solution for your setup. If you're looking for a versatile tool that also handles audio extraction, check our parent guide on the YouTube MP3 converter first.

KEY TAKEAWAYS
  • 4K Video Downloader is the most accessible; yt-dlp is the most flexible
  • A 4K file is four times heavier than a 1080p one: plan storage and bandwidth
  • AV1 codec offers the best compression but needs a recent CPU
  • FFmpeg is required to merge 4K video and audio streams

Why download in 4K instead of 1080p?

The difference between 1080p (Full HD) and 4K (Ultra HD) isn't just a slight bump in resolution: a 4K file contains four times as many pixels as a 1080p file. In practical terms, this means:

  • Finer details: sharp text, visible textures, wide shots that hold up when zoomed in.
  • Better large-screen rendering: on a 55" TV or larger, the difference is immediately visible.
  • Video editing: 4K footage allows cropping in post-production while maintaining HD output quality.
  • Quality archiving: preserving the best available version of content that might be removed.

On the flip side, files are larger, downloads take longer, and decoding is more demanding. That's why choosing the right tool and codec matters.

4K download procedure

  1. Install 4K Video Downloader from the official website (Windows, macOS, Linux).
  2. Copy the URL of a YouTube video available in 4K.
  3. Click "Paste Link" in the application.
  4. In the quality dropdown, select "2160p (4K)" — choose VP9 or AV1 codec for better compression.
  5. Pick the output format (MP4 or MKV) and destination folder.
  6. Start the download.

yt-dlp: 4K setup and configuration

yt-dlp is the Swiss army knife of command-line video downloading. As an actively maintained fork of youtube-dl, it offers the finest control over quality and codec selection. It's the go-to solution for downloading YouTube videos at maximum quality.

Installation

Install yt-dlp and FFmpeg (required for merging separate 4K audio and video streams):

  • Windows: winget install yt-dlp then winget install FFmpeg
  • macOS: brew install yt-dlp ffmpeg
  • Linux: pip install yt-dlp then sudo apt install ffmpeg

Essential 4K commands

List all available qualities to identify 4K streams:

yt-dlp -F URL

Download at best available quality (4K if available):

yt-dlp -f "bestvideo[height>=2160]+bestaudio/best" --merge-output-format mkv URL

Force VP9 codec in 4K (best size-to-quality ratio):

yt-dlp -f "bestvideo[height>=2160][vcodec^=vp9]+bestaudio[acodec=opus]/best" --merge-output-format mkv URL

Force AV1 codec in 4K (maximum compression, available on recent uploads):

yt-dlp -f "bestvideo[height>=2160][vcodec^=av01]+bestaudio[acodec=opus]/best" --merge-output-format mkv URL

Permanent configuration

Create a config file at ~/.config/yt-dlp/config with your default 4K preferences:

-f "bestvideo[height>=2160]+bestaudio/bestvideo+bestaudio/best"
--merge-output-format mkv
--embed-subs
--write-sub
--sub-lang en,fr
-o "~/Videos/YouTube/%(title)s [%(resolution)s].%(ext)s"

This way, every call to yt-dlp URL will automatically fetch 4K when available. To convert the downloaded video to audio format, see our yt-mp3 guide.

JDownloader 2: the versatile download manager

JDownloader 2 is an open-source download manager written in Java that supports hundreds of websites, including YouTube. While less specialized than 4K Video Downloader, it offers solid 4K capabilities.

YouTube 4K configuration

  1. Install JDownloader 2 from the official website.
  2. Go to Settings > Plugins > youtube.com.
  3. In video preferences, enable 2160p resolutions and VP9/H.264 codecs.
  4. Enable "Prefer best quality" in general settings.
  5. Paste the YouTube URL — JDownloader will detect all available streams.

JDownloader advantages for 4K

  • No download limits: no daily restrictions whatsoever.
  • Automatic resume for interrupted downloads — crucial for large 4K files.
  • Advanced queue management with bandwidth control.
  • Cross-platform: runs on Windows, macOS, and Linux via Java.

Limitations

  • Less intuitive interface than 4K Video Downloader.
  • No native AV1 codec support at this time.
  • Requires Java installed on the machine.

Browser methods for 4K downloads

Several browser-based extensions and methods allow 4K video retrieval, with varying results. For a no-install approach, also check our guide on online YouTube converters.

  • Video DownloadHelper (Firefox, Chrome): detects video streams on the page and offers downloads. 4K support requires the companion application.
  • SaveFrom.net Helper: adds a download button below YouTube videos, but limited to 1080p in the free version. No real 4K support.
  • youtube4kdownloader.com: online tool that supports 4K but with slow processing times.

Why browser methods are limited for 4K

YouTube separates video and audio streams above 720p (DASH protocol). Browser extensions typically cannot merge these streams, which is why they usually cap at 720p or 1080p. For genuine 4K downloads, a desktop application with integrated FFmpeg remains essential.

Video codec comparison: H.264 vs VP9 vs AV1

Your codec choice has a major impact on file size, visual quality, and hardware compatibility. Here's a detailed comparison for a 10-minute 4K video:

Criterion H.264 (AVC) VP9 AV1
File size (10 min, 4K) ~1.5 – 2.5 GB ~800 MB – 1.5 GB ~500 MB – 1 GB
Visual quality at equal bitrate Good Very good Excellent
Compression efficiency Baseline ~30-40% better ~50-60% better
Player compatibility Universal Very good Growing
Hardware decoding (GPU) All GPUs Recent GPUs (2016+) Latest GPUs (2020+)
YouTube availability Limited to 1080p Standard for 4K Recent 4K uploads
Container format MP4 WebM / MKV WebM / MKV / MP4

Which codec should you choose?

  • H.264: only choose this if you need maximum compatibility (older TVs, legacy media players). Note that YouTube rarely offers H.264 above 1080p anymore.
  • VP9: the best all-around choice in 2026. Great balance of compression, quality, and compatibility. YouTube's default codec for 4K content.
  • AV1: the most efficient compression, ideal for saving disk space. Verify your player/GPU supports it (VLC 3.0.17+, mpv, Intel 11th gen+, NVIDIA RTX 30+, AMD RX 6000+).

File sizes and disk space requirements

Before bulk-downloading in 4K, estimate the disk space you'll need:

Video duration 1080p (VP9) 4K (VP9) 4K (AV1)
5 minutes ~150 MB ~600 MB ~350 MB
10 minutes ~300 MB ~1.2 GB ~700 MB
30 minutes ~900 MB ~3.5 GB ~2 GB
1 hour ~1.8 GB ~7 GB ~4 GB
2 hours (movie) ~3.5 GB ~14 GB ~8 GB

A 1 TB hard drive can store approximately 140 hours of 4K VP9 video or 250 hours of 4K AV1 video. If you archive regularly, an external drive or NAS is recommended.

Hardware requirements for 4K playback

Downloading in 4K is pointless if your machine can't play the files smoothly. Here are the minimum requirements:

VP9 4K decoding

  • CPU: Intel Core i5 6th generation (Skylake) or AMD Ryzen 1st generation minimum.
  • GPU: Intel HD 530+, NVIDIA GTX 960+, AMD RX 460+ (hardware VP9 decoding).
  • RAM: 8 GB minimum.
  • Player: VLC 3.0+, mpv, MPC-HC with LAV Filters.

AV1 4K decoding

  • CPU: Intel Core i5 11th generation or AMD Ryzen 5000 (software decoding possible but demanding).
  • GPU: Intel Arc/Xe (11th gen+), NVIDIA RTX 3050+, AMD RX 6600+ (hardware AV1 decoding).
  • RAM: 16 GB recommended.
  • Player: VLC 3.0.17+, mpv (with --hwdec=auto).

Without hardware decoding, 4K AV1 playback may stutter on modest machines. In that case, stick with VP9 or download in 1080p instead.

4K downloading best practices

  • Check 4K availability: not all YouTube videos are uploaded in 4K. Look for the "4K" or "2160p" badge in YouTube's quality options.
  • Prefer MKV containers: MKV handles VP9/AV1 + Opus streams better than traditional MP4.
  • Schedule large downloads: 4K files are big — plan bulk downloads during off-peak hours.
  • Keep FFmpeg updated: codecs evolve, and FFmpeg regularly adds decoding improvements.
  • Verify file integrity: play back a few seconds after downloading to confirm the file isn't corrupted.

FAQ — Downloading YouTube in 4K

What is the difference between 4K and Ultra HD?

In practice, the terms are used interchangeably. Technically, "true" cinema 4K is 4096 x 2160 pixels, while UHD (used by YouTube and consumer TVs) is 3840 x 2160 pixels (exactly 4x 1080p). When you download a YouTube "4K" video, you're actually getting UHD at 3840 x 2160. The 256-pixel horizontal difference is imperceptible to the human eye. All tools mentioned in this guide — 4K Video Downloader, yt-dlp, JDownloader — download this native YouTube UHD resolution.

Why does my 4K download have no audio?

This is the most common 4K downloading issue. YouTube uses the DASH protocol (Dynamic Adaptive Streaming over HTTP) which separates video and audio into two distinct streams for resolutions above 720p. If your tool doesn't merge these streams, you get a silent video file.

The fix: use yt-dlp with the bestvideo+bestaudio syntax (which merges automatically via FFmpeg) or 4K Video Downloader which handles merging natively. With JDownloader, ensure the "Merge audio and video" option is enabled in the YouTube plugin settings. For audio-focused solutions, check our page on downloading music from YouTube.

How long does it take to download a 4K video?

The time depends on the codec, video duration, and your internet connection. For a 10-minute 4K VP9 video (~1.2 GB): roughly 2 minutes on 100 Mbps fiber, 5 minutes on 50 Mbps VDSL, or 15 minutes on 15 Mbps ADSL. AV1 files are ~40% smaller, so proportionally faster to download.

Stream merging via FFmpeg typically adds 10 to 30 seconds. For bulk downloads, JDownloader and yt-dlp allow parallelized connections to speed up the process. For a no-install download, try a free YouTube converter online, but note that 4K is rarely available there.
