Step-by-step guide: how to download in 4K
- Open your browser and go to the SaveFrom 4K Video Downloader page.
- Copy the YouTube video URL you want to download from YouTube.
- Paste the URL into the input field on the downloader page.
- Choose your desired format and quality. To save in 4K, select MP4 (or MKV/WebM) at 2160p if available. If you want audio, select MP3 or M4A with a high bitrate.
- (Optional) For the highest fidelity, pick H.265/HEVC or VP9 codecs when offered, and adjust the bitrate if the option is shown.
- Click the Download/Convert button. The tool will fetch the video and start the conversion. You'll see a progress indicator and an estimated time remaining.
- Once the conversion finishes, your browser will prompt you to save the file. Choose a location on your device and start enjoying your 4K video or audio file.

Tip: If a video isn't available in 4K, the downloader will automatically offer the best available resolution (for example 1080p or 720p). You can still extract high-quality audio from most videos.

- WebM – modern, browser-friendly format often used for streaming and web playback, available in high resolutions.

Codecs and technical details

4K specifics: what you can expect
4K (2160p) provides the sharpest, most detailed picture available for consumer video. When you download in 4K, you are preserving a higher level of detail, which is especially noticeable on large screens and high-DPI displays. Availability of 4K depends on the video's original source. Some videos are posted in 4K; others are available up to 1080p or 1440p. The downloader will surface the best 4K option if the video supports it, and otherwise offer the best alternative. Expect larger file sizes and longer download times for 4K videos, typically measured in gigabytes per hour of video content.
Quality options and how to choose
- Choose 4K when you have a 4K display or plan to view on a big screen where detail matters.
- Choose 1080p or 720p for smaller devices or slower connections to reduce file size and download time.
- For audio-focused needs, select MP3 or M4A at 192–320 kbps for high fidelity.

How this compares with other formats
In many cases, users compare 4K video downloads with other formats like 1080p MP4, 720p MP4, or audio-only extractions. Here are some practical comparisons to help you decide which option to choose.
- 4K MP4 vs 1080p MP4: 4K offers more detail and a larger file size; 1080p is smaller and quicker to download, which may be preferable for mobile viewing or limited storage.
- 4K MKV vs MP4: MKV can be more flexible with multiple audio tracks or subtitles, but MP4 is more universally compatible with devices and media players.
- Audio-only (MP3/M4A) vs video: If your goal is listening on the go, audio formats save space and bandwidth, but you lose video quality.
Use cases: why you'd want 4K YouTube downloads
