Paste any YouTube link to test whether its thumbnail is public. Unlisted and most age-restricted videos work; private and deleted videos return a gray placeholder because no public image exists.
This tool works by fetching the copy of a thumbnail that YouTube keeps on its public image server. Whether that copy exists depends on the video's privacy state, not on the tool. An unlisted video keeps a public thumbnail, a private video does not, and deleted or age-restricted videos each behave differently. Here is what you can and cannot get for each case, and what to do when the image is not public.
Unlisted videos have a public thumbnail, so the tool grabs them normally once you have the link. Age-restricted videos usually keep a reachable thumbnail because the restriction limits who can watch, not the image file. Private videos have no public thumbnail at all, so only the owner can retrieve it. Deleted videos lose their thumbnail once they are gone, though an archive copy sometimes survives. The sections below cover each one.
Unlisted is not the same as private. An unlisted video is hidden from search, your channel page, and recommendations, but anyone who has the link can open it, and YouTube stores its thumbnail on the same public image server as any normal video. That means the grabber works exactly the way it does for a public video: paste the unlisted link into the box above, click Get Thumbnail, and download the size you want. The only catch is that you need the link in the first place, because there is no way to search for an unlisted video. If you have the URL, see how to find a YouTube thumbnail for the fastest routes.
A private video can only be watched by the owner and the specific people they invite, and YouTube does not publish a thumbnail for it on the public image server. Paste a private video's link and the tool returns the gray 120x90 placeholder for every size, because there is simply no public file to fetch. No third-party tool can get around this; the image is not withheld by us, it is not exposed by YouTube. If the video is not yours, the only real option is to ask the owner for it. If it is your own private video, the next section shows how to pull it from YouTube Studio.
Age restriction controls who is allowed to watch a video and often blocks playback on third-party sites, but it applies to the video, not to the static thumbnail file sitting on YouTube's image server. In practice that means the thumbnail is usually still reachable, and the tool can grab it like any other video. Treat this as the common case rather than a guarantee: if a specific size comes back as a gray box, that is the normal missing-size behavior, and the tool falls back to the largest size that does exist. The YouTube thumbnail URL guide lists that fallback order in full.
Once a video is deleted by its creator or removed by YouTube, the thumbnail stops being served and you get the gray placeholder. There is no live copy to download anymore. If you still have the original video URL, it is worth pasting that URL into the Wayback Machine at web.archive.org, which sometimes captured the video page or the thumbnail image before it went down. This is a maybe, not a method: an archived copy either exists or it does not. For a video that is still live but simply changed its thumbnail, that same archive can show its past thumbnails over time. If you only have the picture and want to trace where else it appears, work the opposite direction with a reverse image search of the thumbnail.
The tool tells you quickly. Paste the link, open a size, and read the result. A real image means the thumbnail is public, which is what you expect for unlisted and most age-restricted videos. A small gray 120x90 image on the largest size, and on every fallback size, means there is no public thumbnail, which points to a private or deleted video rather than a missing resolution. A gray box on only the top size while smaller sizes load fine is a different thing entirely: it just means the HD file was never generated. That missing-size case is covered in why a YouTube thumbnail is not showing or is a gray box.
If the private video is yours, you do not need a public URL at all. Open YouTube Studio, go to Content, and click the video. The custom thumbnail appears in the details, and you can download it from the thumbnail box or right-click the preview and choose Save image as. If you would rather use the grabber, change the video's visibility to Unlisted for a moment, paste the link here to save the thumbnail, then switch it back to Private. To replace that image entirely, see how to change a YouTube thumbnail.
Not if it is someone else's private video. A private video is only visible to the owner and invited viewers, and YouTube publishes no public thumbnail for it, so the tool returns a gray placeholder. If it is your own, save it from YouTube Studio, or set the video to unlisted first.
Yes. Unlisted videos are hidden from search but watchable by anyone with the link, and their thumbnail lives on the same public image server as any normal video. Paste the unlisted link above and the tool works as usual.
Usually yes. Age restriction gates who can watch, not the static thumbnail file, so the image is typically still reachable and the tool can grab it. A missing size just falls back to a smaller one.
Usually not directly, because YouTube stops serving the image once the video is gone. If you kept the original URL, paste it into the Wayback Machine to check for an archived copy, though there is no guarantee one exists.
A gray 120x90 box on one size means that exact size does not exist, not that the video is private. YouTube only makes the 1280x720 file for HD or custom-thumbnail uploads. The tool falls back to the largest size that exists, so use that button. See the gray-box guide for more.
Open YouTube Studio, go to Content, click the video, and download the custom thumbnail, or right-click the preview and save it. If you prefer the grabber, switch the video to unlisted, save the thumbnail here, then switch it back to private.
