How can I download 4k video from youtube on my computer?

It depends on the source video. If it is in 4k video quality, then you can download youtube video 4k using a app like Stacher, which is a completely free, open-source desktop application for downloading youtube video in 4K.

Instead of typing commands in a terminal, you can download YouTube videos in high quality, including 4K (2160p), using a simple, modern interface on Windows, macOS, and Linux.

Because Stacher relies on yt---dlp in the background, it inherits the same strong compatibility with YouTube updates, adaptive streams, and high-resolution formats. This makes it far more reliable than most browser extensions or online downloaders, especially when dealing with 4K videos that use separate video and audio streams.

Steps to Download YouTube Videos in 4K with Stacher

1. Download and install Stacher from its official website or GitHub page.

2. Launch Stacher on your PC or Mac.

3. Copy the YouTube video URL and paste it into the Stacher input box.

4. Open Settings → Quality / Format.

5. Select Best Video + Best Audio or explicitly choose 2160p (4K).

6. Choose the output format (MP4 or MKV is recommended for 4K).

7. Click Download and wait for Stacher to merge video and audio automatically.
