Q. Can I reuse a thumbnail I downloaded?A. Opening or downloading a public thumbnail for research is different from republishing it. Reuse can create copyright risk, so check rights and rebuild with your own assets, framing, and text.Q. Why is HD not always available?A. YouTube's upload best practice is 3840 x 2160, at least 640px wide, and 16:9. 1280 x 720 remains useful as a public-preview and A/B-test 720p floor, but GrabThumbs can only open the sizes YouTube actually exposes for each video or Shorts URL.Q. Is GrabThumbs a YouTube thumbnail extractor, downloader, or grabber?A. Yes. Those search phrases describe the same public-thumbnail workflow: paste a public YouTube or Shorts URL, open available thumbnail sizes, download when useful, or copy the public image URL.Q. Does GrabThumbs work for YouTube Shorts thumbnails?A. Paste the Shorts URL just like a regular video link. If YouTube exposes a public thumbnail image for that Shorts URL, GrabThumbs lets you open it, download it, or copy the public image URL.Q. Can I copy the image URL without downloading the file?A. Yes. Use Copy Image URL in the result workspace when you only need the public image link for research notes, sharing, or quick comparison.
