Want to save YouTube videos in 480p, 720p, 1080p, 4K or 8K quality in Australia? Our YouTube 4K / 8K Downloader is a free online tool that saves your favourite YouTube videos in ultra HD, with MP4, WebM and MKV formats plus MP3 audio. It works smoothly on PC, Mac, Android and iPhone, without installing any software.
1080p (Full HD) is 1,920×1,080 pixels. 4K (2160p) is 3,840×2,160 pixels — four times the detail of 1080p. 8K (4320p) is 7,680×4,320 pixels — four times more than 4K. Higher resolution means better visuals, but also a much larger file size, so always check your device's storage and connection before saving ultra HD media, especially on mobile data.
Video editors, filmmakers and content creators often need 4K or higher resolution for their work. For lectures, podcasts and everyday entertainment, 720p or 1080p is usually the better choice, since it balances file size with smooth playback and uses less data.

Before you download
How to Check if a Video Has 4K or 8K Quality

Tap Quality, then Advanced.

Good to know
Why You Might Not See a 4K or 8K Option
The original upload is in 1080p or lower quality.
Newly released media can take time before higher qualities become available.
An unstable internet connection is preventing the higher rungs from loading.
Your device does not support playback at that resolution.
Best Format for 4K and 8K Downloads
- MP4 is the best choice for most people — it plays on almost every device, app and media player.
- WebM offers strong quality at a smaller file size, when your media player supports it.
- MKV keeps audio, subtitle and video tracks together in one file.
How to Play 4K and 8K Videos Smoothly
- Use a capable media player, such as MX Player, PotPlayer, IINA, MPC-HC or VLC.
- 8K playback needs a modern CPU, GPU, more RAM and free storage than most 4K-ready devices have.
- If a video buffers or stutters, update your graphics driver, close other tabs, or connect to a more stable network.
