8K UHD 7680 × 4320 ~80 Mbps ~300 MB Future-proofing, 8K displays

Our recommendation: For most users, 1080p Full HD provides excellent visual quality on any modern screen while keeping file sizes manageable. Choose 4K only if you specifically need ultra-high resolution for a 4K display or video editing.

YouTube Video Download FAQ

Common questions about downloading YouTube videos in MP4

It depends on your device and available storage. 1080p Full HD is the sweet spot for most users — excellent quality with reasonable file size. Choose 4K only if you have a 4K display and sufficient storage. 720p is perfect for mobile viewing and saves significant storage space.
Yes! YouTuDown supports 4K Ultra HD (2160p) video downloads. Note that the source video must be available in 4K on YouTube. If it's not, we'll automatically provide the highest available quality. 4K files are significantly larger — a 5-minute 4K video can be 350MB or more.
MP4 (H.264) is the most universally compatible video format, playing on virtually every device, TV, and media player. WEBM (VP9) offers slightly better compression at the same quality but has limited compatibility, mainly supported in web browsers and some media players. For maximum compatibility, always choose MP4.
File sizes vary by resolution. For a 5-minute video: 360p ≈ 25MB, 720p ≈ 75MB, 1080p ≈ 150MB, 4K ≈ 350MB. Actual sizes depend on the video's visual complexity and encoding settings. Action-heavy videos with lots of motion tend to be larger.
Yes! Open YouTuDown in Safari, paste the video URL, and select your preferred quality. When the download link appears, tap and hold the download button, then select "Download Linked File." Find the downloaded video in your Files app under the Downloads folder.
