YouTube Thumbnail Grabber
Paste any YouTube link to get its thumbnail image in every size.
Every YouTube video has thumbnail images at fixed URLs. Paste a link and this returns the max, SD, HQ and MQ image links so you can open or save whichever size you need.
This is built from the video id, so it is instant and stores nothing.
Questions
How do I download a YouTube thumbnail?
Paste the video link above, then open the size you want and save the image.
Why is the max resolution image missing?
The 1280x720 version exists only when the uploader provided one. If it does not load, use the SD or HQ link.
