Download any YouTube video thumbnail in all available sizes

Paste a full watch URL (youtube.com/watch?v=...), a share link (youtu.be/...), a Shorts URL, or the raw ID, and the tool returns the available thumbnail resolutions so you can view or save the JPG directly.
It is used by content creators auditing their own thumbnails, video editors and designers who need reference images, researchers archiving video metadata, and writers who want a clean still for blog posts or social cards. Because YouTube generates several fixed sizes per video, the tool exposes each one so you can grab the exact resolution you need.
Every YouTube video has a unique 11-character ID, found after v= in a watch URL or after the slash in a youtu.be link. YouTube stores thumbnails at predictable, public image URLs built from that ID, in the form https://img.youtube.com/vi/VIDEO_ID/NAME.jpg. The tool simply parses the ID out of whatever link you paste and constructs those image URLs for you.
YouTube generates a fixed set of named sizes: default (120x90), mqdefault (320x180), hqdefault (480x360), sddefault (640x480), and maxresdefault (1280x720). It also creates numbered frame grabs (0.jpg, 1.jpg, 2.jpg, 3.jpg) captured from the start, one-quarter, and midpoints of the video. The hqdefault and default sizes exist for essentially every video, while sddefault and maxresdefault are only present for videos uploaded at higher resolutions.
Thumbnails are served as JPEG files. The maxresdefault version reflects the exact custom thumbnail an uploader set (or the highest-quality auto-generated frame), which is why it is the best choice for print or high-DPI display when it is available. All requests hit YouTube's own image CDN, so the tool does not host or cache any images itself.
Yes, it is completely free with no sign-up. The tool only parses the video ID from the link you paste and points to YouTube's public image CDN, so no account details or personal data are collected or stored.
YouTube only generates the 1280x720 maxresdefault image for videos uploaded at HD resolution or with a high-quality custom thumbnail. For older or lower-resolution videos, use hqdefault (480x360) or sddefault (640x480) instead.
It works with standard watch URLs (youtube.com/watch?v=...), short youtu.be links, Shorts URLs, embed URLs (youtube.com/embed/...), and a bare 11-character video ID pasted on its own.
Thumbnails are only reachable for public and unlisted videos whose image URLs YouTube serves openly. Fully private videos are not accessible, since their thumbnails are not exposed on the public CDN.
All thumbnails are JPEG files. The standard sizes are 120x90, 320x180, 480x360, 640x480, and 1280x720, plus numbered frame grabs taken from points across the video.
Downloading is technically simple since the images are public, but the thumbnail is still the uploader's copyrighted content. Use it within fair use, or get permission before republishing someone else's thumbnail commercially.
No. Everything runs in your browser using YouTube's public image URLs, so there is no software to install, no extension, and no API key required.
