Download YouTube videos as MP4 files
MP4 is the safest format for video downloads — your phone plays it, your laptop plays it, the USB stick plugged into your car plays it, smart TVs play it, and you can edit it in any video editor. SnapVid gives you direct MP4 downloads of any public YouTube video at whatever resolutions YouTube has encoded.
The files come straight from YouTube's own CDN (googlevideo.com) to your device. There's no middle server slowing things down, no compression beyond what YouTube already applied, and no quality loss. What you download is bit-for-bit what YouTube serves to its own player when you watch the video in your browser.
Common uses: saving tutorials to watch offline on flights or commutes, archiving lectures and conference talks before they're removed, pulling reference clips into a video editor, downloading travel vlogs for plane rides, grabbing music videos for a wedding playlist, saving cooking videos to follow while your hands are busy, and keeping a personal copy of important content before channels go private or get terminated.
MP4 quality guide
Higher resolution means bigger file. For a phone or tablet, 720p is usually plenty. For a laptop or TV, 1080p is the sweet spot. For video editing or projection, go 4K when available. Here's the rough size estimate per minute of video so you can pick before you click:
| Quality | Resolution | ~Size per minute | Use case |
|---|---|---|---|
| 360p | 640×360 | ~4 MB | Slow connection, small phone |
| 720p | 1280×720 | ~10 MB | Phone, tablet, casual viewing |
| 1080p HD | 1920×1080 | ~18 MB | Laptop, TV, most modern displays |
| 1440p (2K) | 2560×1440 | ~30 MB | High-end monitors |
| 2160p (4K) | 3840×2160 | ~60 MB | 4K TVs, professional editing |

Why MP4 (and not WebM, MKV, or AVI)?
YouTube stores videos in two main containers: MP4 (using the H.264 or AV1 codec) and WebM (using the VP9 codec). MP4/H.264 is the most universally compatible — every phone, tablet, laptop, smart TV, and gaming console from the last fifteen years plays it natively. WebM, while technically more efficient, doesn't play on iPhones without third- party apps and isn't supported by older devices.
SnapVid defaults to MP4/H.264 for that reason. If you specifically need WebM for editing or storage, those formats are sometimes listed separately. For 99% of users, MP4 is what you want.
About 1080p, 4K, and "no audio"
One quirk to know: YouTube splits high-resolution video and audio into separate streams. When you watch a 1080p video in your browser, YouTube's player downloads both streams and combines them in real time. For direct downloads, that means some 1080p+ files come as video-only (no audio track).
We mark these clearly as "(no audio)" so you know what you're getting. If you need a single file with both video and audio at 1080p+, you'd typically download both streams and merge them with a tool like ffmpeg. For most users, 720p MP4 (which always includes audio) is the practical sweet spot.
Frequently Asked Questions
What MP4 qualities are available? +
Whatever YouTube has encoded for that video — typically 360p, 480p, 720p, 1080p, and sometimes 1440p (2K) and 2160p (4K). SnapVid shows all available qualities with file sizes.
Does the MP4 include audio? +
The 360p MP4 download includes both video and audio in one file. Higher resolutions (720p+) sometimes come as video-only streams — we mark these as 'no audio' so you know which to pick.
Will the file play on my phone / iPhone / TV? +
Yes. MP4 with H.264 codec (what YouTube serves) plays on every modern device — iPhone, Android, Windows, Mac, Smart TVs, gaming consoles, USB sticks plugged into your car. It's the most universally supported video format.
How big is a YouTube MP4 download? +
Depends on length and quality. Roughly: 360p ≈ 4 MB/min, 720p ≈ 10 MB/min, 1080p ≈ 18 MB/min, 4K ≈ 60 MB/min. SnapVid shows the exact file size before you download.
Can I download YouTube Shorts as MP4? +
Yes. Paste the Shorts URL (the one starting with /shorts/) and you'll get the vertical MP4 file.
Why is the download URL hosted on googlevideo.com? +
That's YouTube's CDN. The file goes directly from Google's servers to your device — SnapVid doesn't proxy the bytes through our servers, so downloads are as fast as your internet connection allows.
Is downloading YouTube videos legal? +
It depends on where you live and what you do with the file. YouTube's Terms of Service prohibit downloading without permission. In many countries, downloading copyrighted content for personal offline use exists in a legal grey area. Always respect copyright — download content you own, public domain content, or Creative Commons content.
Why is the file size so much smaller than YouTube shows? +
YouTube reports total bandwidth used by its player, which streams chunks repeatedly during seeking and re-buffering. The actual MP4 file is much smaller. A 10-minute 1080p video is usually 150-250 MB, not the multi-GB figure YouTube's stats might suggest.
