Method 1: Use a thumbnail downloader (fastest)
- Copy the video’s link. On a computer, copy it from the address bar. In the YouTube app, tap Share → Copy link.
- Open the GrokThumbnails thumbnail downloader and paste the link.
- Press Get thumbnails, choose a size, and press Download.
This works for regular videos, Shorts, live streams and youtu.be short links, on any device.
Method 2: Build the image URL yourself
Every YouTube thumbnail lives at a predictable address. Find the 11-character video ID — it’s the part after v= in a watch link, after youtu.be/ in a short link, or after /shorts/ for Shorts. Then put it into one of these URLs:
| Size | URL pattern |
|---|---|
| 1280 × 720 | https://i.ytimg.com/vi/VIDEO_ID/maxresdefault.jpg |
| 640 × 480 | https://i.ytimg.com/vi/VIDEO_ID/sddefault.jpg |
| 480 × 360 | https://i.ytimg.com/vi/VIDEO_ID/hqdefault.jpg |
| 320 × 180 | https://i.ytimg.com/vi/VIDEO_ID/mqdefault.jpg |
| WebP version | https://i.ytimg.com/vi_webp/VIDEO_ID/maxresdefault.webp |
Open the URL in your browser, then right-click (or long-press on mobile) and choose Save image as.
Method 3: On iPhone and Android
iPhone (Safari)
- In the YouTube app, tap Share → Copy link.
- Open Safari, go to grokthumbnails.com and paste the link.
- Tap Download, or long-press the image and choose Save to Photos.
Android (Chrome)
- Copy the link from the YouTube app.
- Paste it into the downloader in Chrome.
- Tap Download. The image goes to your Downloads folder and appears in your gallery.
Why is the HD thumbnail missing?
The maxresdefault image only exists when the video was uploaded in 720p or higher, or the creator uploaded an HD custom thumbnail. Older or low-resolution videos only have the smaller versions. In that case YouTube returns a small grey placeholder. Use sddefault or hqdefault instead — they are always available.
Can you use a downloaded thumbnail?
Thumbnails are the creator’s copyrighted work. Saving one for personal reference, research or to study design patterns is common. Reusing it in your own video, re-uploading it as your own, or using it commercially generally needs the creator’s permission. When in doubt, ask, and always credit and link to the original video.
What to do after downloading
Downloading top thumbnails is a great way to learn. Try:
- Extracting their colours with the palette extractor.
- Checking how they handle the timestamp with the safe zone checker.
- Comparing your design against them in the A/B compare tool.
Frequently asked questions
What is the URL of a YouTube thumbnail?
https://i.ytimg.com/vi/VIDEO_ID/maxresdefault.jpg for HD, replacing VIDEO_ID with the 11-character ID from the video link. Smaller versions use sddefault, hqdefault, mqdefault or default.
How do I download a YouTube thumbnail on iPhone?
Copy the video link in the YouTube app, paste it into the GrokThumbnails downloader in Safari, then tap Download or long-press the image and choose Save to Photos.
Is it legal to download YouTube thumbnails?
Viewing and saving a public image for personal use is generally fine, but the thumbnail remains the creator’s copyrighted work. Don’t reuse it publicly or commercially without permission. This isn’t legal advice.
