Frequently Asked Questions
Why do some YouTube downloaders only go up to 1080p? ▼
YouTube encodes 4K (2160p) as an adaptive DASH stream that is video-only — no audio is bundled. Downloading it requires fetching a separate audio stream and merging both. Many tools skip this step, so they're limited to the older progressive MP4 format which caps at 1080p.
Which codec is better for 4K — VP9 or AV1? ▼
AV1 provides better compression than VP9 at the same visual quality, meaning smaller file sizes. However, AV1 hardware decoding support varies by device. VP9 is more widely supported. Snapvie lets you choose the codec that matches your playback setup.
How large are 4K YouTube video downloads? ▼
File size depends on video length and codec. A 10-minute 4K VP9 video typically ranges from 400 MB to 1.2 GB. AV1 files are 20-30% smaller. Snapvie shows estimated quality tiers before you download so you can pick the right size/quality tradeoff.
Can I download 4K videos on a mobile device? ▼
Yes. Snapvie works in any modern mobile browser. The 4K file will download to your phone storage. Note that playing back 4K files smoothly requires hardware decoding support, which most flagship phones released after 2019 have.
Do I need an account to use Snapvie? ▼
No account required. Paste a URL, select quality, and download. No sign-up, no email, no login.
What quality should I download YouTube videos at for offline viewing? ▼
Match the quality to your screen. 1080p covers most laptops and monitors. Download 4K only if you have a 4K display or want an archive-quality copy. Higher quality means larger files — a 1-hour video at 4K can be 3–5 GB.
