Tip: If you're not sure which format to pick, MP4 with H.264/AVC is the most widely compatible option across devices and apps, while 4K WebM with VP9 can offer efficiency in certain browsers. Always check the video's native resolution on YouTube to confirm 4K availability before downloading in 4K.
Vidloader's 4K YouTube Downloader supports a range of video and audio formats. Here's a quick guide to what you can expect and when to choose each option:
4K resolution (2160p) provides the sharpest image, especially on large screens and modern TVs. Use 4K when preserving detail matters, such as cooking videos, travel footage, or cinematic clips. If your device or bandwidth is limited, you can always choose 1080p or 1440p as a practical alternative that still looks great on most displays.
Understanding the technical side helps you pick the right option for your workflow. Here are typical, general ranges you may encounter when downloading from Vidloader's 4K YouTube Downloader. Actual numbers vary by video and source encoding:
When you select 4K MP4, you'll usually get a balance of excellent picture quality and broad compatibility. If you want maximum efficiency and you're using a compatible browser or device, 4K WebM (VP9/VR or VP9 in WebM) can be an attractive option, particularly for web playback.
Vidloader's 4K YouTube Downloader is browser-based, which means it works on any device with a modern browser — Windows, macOS, Linux, iOS, and Android. Because the process happens in your browser, you don't need to install desktop software or extensions. Here's how it translates to real-world use:
Because the tool is designed to be fast and lightweight, you won't experience heavy resource usage on typical devices. If you encounter any issue with a specific video, try a lower resolution option or a different container format to ensure compatibility with your software.
There are several scenarios where downloading a video in 4K makes sense:
If you don't need 4K right away, you can always pick 1080p or 1440p to save bandwidth and storage while still delivering excellent viewing experiences on most devices.
When choosing between formats, it's helpful to compare key aspects: compatibility, file size, and playback quality. Here are quick guidelines:
| Format | Quality | File Size (approx) | Compatibility | Best Use |
|---|---|---|---|---|
| MP4 (H.264/AVC) | Excellent | Medium to large | Very broad | General purpose, devices, editors |
| MP4 (H.265/HEVC) 4K | Very high | Smaller than H.264 at same quality | Modern devices, some editors | 4K playback with efficiency |
| WebM (VP9/AV1) | High, efficient | Lower than H.264 in some cases | Modern browsers and Android | Web playback, streaming |
| MKV | High | Variable | Editors, some players | Flexible containers |
For audio-only downloads, MP3 and M4A provide compact, widely compatible options. If you're prioritizing web delivery, WebM codecs can offer advantages in supported browsers. Remember, the availability of 4K depends on the original video and its encoding; some videos may not be encoded in 4K or may have limited 4K bitrate options.

Commonly supported formats for 4K downloads include MP4 (H.264/AVC or H.265/HEVC) and WebM (VP9). MP4 remains the most universally compatible format across devices and editors.
