How to Do a YouTube Giveaway: Rules, Ideas & Picking a Winner
Step-by-step guide to running a YouTube giveaway: clear rules, YouTube’s contest policies, prize ideas, and how to pick a random winner from comments fairly.
Paste any YouTube video or Shorts link and save its thumbnail in every size YouTube offers — up to HD 1280×720.
“Not available” means YouTube never generated that size — usually because the video was uploaded below 720p. Learn why.

How it works
No fake “1080p”
YouTube automatically makes several copies of every thumbnail. We show exactly which ones exist for your video and grey out the rest — YouTube doesn’t store 1080p or 4K thumbnails, so we never pretend it does.
Read the size guide| Quality | Resolution | Available |
|---|---|---|
| HD maxresdefault | 1280 × 720 | HD uploads |
| SD sddefault | 640 × 480 | Most videos |
| High hqdefault | 480 × 360 | Always |
| Medium mqdefault | 320 × 180 | Always |
| Small default | 120 × 90 | Always |

Yes. There is no sign-up, no download limit and nothing to install. The tool runs in your browser and loads the images straight from YouTube’s own image server.
The largest image YouTube generates is 1280×720 pixels (called “maxresdefault”). YouTube does not store 1080p or 4K thumbnails, so any site offering a “1080p thumbnail” is simply upscaling the 720p file.
YouTube only creates the 1280×720 version when the video was uploaded in HD (720p or higher). Older or low-resolution uploads only have the 640×480 and smaller sizes.
Yes. Paste a youtube.com/shorts/… link and you’ll get the same set of thumbnail sizes. The saved images are landscape (16:9 or 4:3), because that is how YouTube stores Shorts thumbnails.
Yes. Tap “Download”. If your mobile browser opens the image in a new tab instead, long-press the image and choose “Save image” or “Download image”.
Thumbnails are owned by the channel that made them. Using them for reference, research, commentary or restoring your own artwork is generally fine; re-uploading someone else’s thumbnail as your own is not. When in doubt, ask the creator.
