Frequently asked questions
Why is the HD thumbnail sometimes blank?
Older or low-resolution uploads have no 1280×720 thumbnail — use the HQ size instead.
Where do the images come from?
They load directly from YouTube's public image CDN (img.youtube.com). This tool never downloads or hosts the video itself.
Can I download someone else's thumbnail?
Only if you own it or have permission. Thumbnails are copyrighted images — use them for reference, not re-upload.
What is a YouTube video ID?
The 11 characters after v= in a YouTube URL, for example dQw4w9WgXcQ. Paste the full link and the tool finds it for you.
