Frequently Asked Questions
Is it legal to download YouTube thumbnails?
Always respect YouTube's Terms of Service and applicable copyright laws. Downloaded thumbnails should be used only in ways permitted by the content owner's license or applicable fair use exceptions.
What resolutions are available?
We attempt maxresdefault (highest), then sddefault, hqdefault, mqdefault, and default. Availability depends on whether the creator uploaded a high-resolution thumbnail.
Does this tool store or upload my data?
No. Everything runs locally in your browser; nothing is uploaded or stored on our servers.
Will the download button always save the file?
Some browsers may open the image in a new tab for cross-origin resources. You can still right-click and save the image if the download prompt doesn't appear automatically.
Do I need any extensions or accounts?
No extensions, no login. The tool works entirely in your browser using standard web APIs.
Can I use this on mobile devices?
Yes. It's responsive and works on modern mobile browsers. Use long-press to save images if needed.
Does this alter or compress the image?
No. The image is fetched directly from YouTube's static servers; we do not modify the file.
