YouTube Thumbnail Downloader
Paste a YouTube URL to see and download every thumbnail resolution that actually exists for that video — missing sizes are shown as "not available" instead of a broken image, since not every video has a maxresdefault.
How it works
- Paste a YouTube video URL or ID
- All 5 standard thumbnail resolutions load, from lowest to highest
- Download any size that's available — sizes the video doesn't have are marked clearly instead of showing a broken image
Frequently asked questions
Why is the highest resolution (maxresdefault) missing for some videos?
YouTube only generates that size for some videos — it depends on what the uploader provided, not on this tool. This tool checks and tells you plainly when a size isn't available instead of showing a broken image or pretending it worked.
Does this scrape YouTube or use an API key?
No — YouTube thumbnails are served from predictable URLs (img.youtube.com/vi/{id}/{quality}.jpg). This tool just constructs and checks those URLs directly in your browser.
Is there a watermark on the downloaded image?
No — you get the original thumbnail file exactly as YouTube serves it.
