Questions creators ask before reusing thumbnail ideas
Use this page when you need the short answer first, then move into the downloader, creator tools, or guides for deeper workflow help.
Core questions
These answers match the boundaries already explained on the homepage and in the related guides.
Is it legal to reuse someone else's thumbnail?v
Downloading a public thumbnail for research is different from republishing it as your own creative asset. Reuse without permission or transformation can create copyright risk.
What thumbnail size should I optimize for?v
1280 x 720 at a 16:9 ratio is still the standard target. Use that size when you are planning new packaging or checking legibility.
Why does the opened thumbnail sometimes look smaller than expected?v
Some videos were published with a smaller source image. GrabThumbs can only open the public image versions that actually exist for that video.
