YouTube Thumbnail Downloader
Paste a video link or ID and get its public thumbnails in every resolution — preview at full size, then copy the URL, open the image or save it. Runs entirely in your browser.
Get the thumbnails
Everything below updates as you type. No button, no waiting, no upload.
How it works
Three steps, no round-trip to a server.
Drop in a watch link, a youtu.be short link, a /shorts/ or /embed/ URL — or just the 11-character ID. Query strings and timestamps are stripped for you.
The video ID builds five public i.ytimg.com thumbnail URLs. Each one is probed in your browser, so sizes YouTube never published are labelled instead of silently showing a grey placeholder.
Copy the direct URL, open the image in a new tab, or download it with your filename prefix. Right-click → Save image as… always works as a backup.
What you get
No sign-in, no upload, no queue. Your video URL never touches a server — the page only assembles image URLs in JavaScript.
maxresdefault 1280 × 720, sddefault 640 × 480, hqdefault 480 × 360, mqdefault 320 × 180 and default 120 × 90, each with pixel dimensions.
Many videos have no 1280 × 720 thumbnail. That case is detected automatically and the preview falls back to hqdefault with a clear label.
Every resolution gets three actions, plus a sticky action bar on phones so the current size is always one tap away.
Set a prefix once; downloads are named prefix-size-videoid.jpg with unsafe characters replaced.
Parsing and URL building happen locally in well under a millisecond — the only wait is the image download itself.
FAQ
Why does maxresdefault sometimes look like a tiny grey image?
YouTube answers missing sizes with a 120 × 90 placeholder instead of a real error. This tool measures the loaded image: if it is smaller than the size it claims to be, the resolution is marked “placeholder / not available” and the preview falls back to hqdefault. You can still copy or open that URL — it simply is not the full-size image.
The download button did not save the file. What now?
Some browsers block cross-origin downloads from i.ytimg.com. Use Copy URL and paste it into a new tab, or right-click the preview (long-press on mobile) and choose “Save image as…”. Both routes always work.
Which links are accepted?
youtube.com/watch?v=…, youtu.be/…, youtube.com/shorts/…, youtube.com/embed/…, youtube.com/live/… and the bare 11-character video ID (letters, digits, dash and underscore). Links from other sites are rejected with guidance rather than a broken image.
Do you store my links or the images?
No. There is no upload, no account and no server-side fetch: the page builds the image URLs itself and your browser loads them straight from YouTube’s image host.
Am I allowed to use someone else’s thumbnail?
Thumbnails are the copyright of their creators and usage is covered by YouTube’s terms. Use them for reference, research or work you are entitled to do — this tool only shows you where the public image lives.
