Frequently asked questions
How do I download a YouTube thumbnail?
Paste any YouTube URL (or just the 11-character video ID) into the field above. We construct the thumbnail URLs from YouTube's CDN (i.ytimg.com) for every available resolution — Max (1280×720), SD (640×480), HQ (480×360), MQ (320×180), Default (120×90). Click Download ↓ on the size you want and the file saves locally. No signup, no software install, no email required.
How do I save a YouTube Shorts thumbnail?
Same workflow as a regular video. Paste the /shorts/<id> URL, the tool extracts the video ID and pulls thumbnails from YouTube's CDN. Shorts use the same thumbnail URL format as long-form videos. Note: many Shorts only have hqdefault available (no maxresdefault) because creators upload them through phone clients that don't request high-res thumbnail generation.
What's the YouTube thumbnail size in pixels?
YouTube generates up to five resolutions per video: 1280×720 (maxresdefault, the recommended size for new uploads), 640×480 (sddefault), 480×360 (hqdefault), 320×180 (mqdefault), and 120×90 (default). For your OWN uploads, YouTube recommends submitting at 1280×720 with a 16:9 aspect ratio and under 2 MB.
Why is maxresdefault.jpg returning a 404?
YouTube only generates the 1280×720 maxresdefault for uploads that meet two conditions: the source video was at least 1280px wide AND the upload finished processing high-resolution thumbnails. Older videos, mobile-recorded clips at lower resolutions, and most Shorts skip this tier. Use hqdefault.jpg (480×360) — it always exists for any public video.
How do I get the YouTube thumbnail URL link?
Right-click the preview image above and "Copy image address", or look at the Download link's href. The URL pattern is i.ytimg.com/vi/<videoId>/<size>.jpg — for example https://i.ytimg.com/vi/dQw4w9WgXcQ/maxresdefault.jpg. You can hotlink to YouTube's CDN; YouTube serves these public thumbnails with permissive caching.
Is it legal to download YouTube thumbnails?
For research, retention analysis, or fair-use editorial commentary — generally yes. For reuploading as your own creative work or commercial use — no. The thumbnail is the creator's intellectual property. Most uses of this tool (comparing CTRs across competitors, archiving your own thumbnails, design study) fall under fair use, but read your jurisdiction's rules before redistributing.
Can I download a YouTube thumbnail in HD or 4K?
The highest resolution YouTube serves publicly is 1280×720 (maxresdefault). YouTube does NOT publish 4K thumbnails — those don't exist as files in their CDN, no matter what the source video resolution was. If a tool claims to download a "4K YouTube thumbnail" it's upscaling the 1280×720 with an algorithm; the actual source data tops out there.
Why does my downloaded thumbnail look small or blurry?
If the file says 480×360 or 320×180 it's because YouTube didn't generate maxresdefault (1280×720) for that video — common on Shorts, mobile uploads, and older content. The tool always shows which sizes are actually available. There's no way to recover detail YouTube didn't store; ask the original creator for their source thumbnail file if you need higher resolution.
Where does this tool send my YouTube URL?
Nowhere. The tool runs entirely in your browser — paste a URL, JavaScript extracts the 11-character video ID locally, and constructs the thumbnail URLs deterministically. Thumbnail downloads stream directly from YouTube's CDN to your machine. We don't log, store, or proxy anything. Open DevTools → Network to verify.
