YouTube Thumbnail Grabber and Size Preview
Paste a YouTube video URL and grab available thumbnail resolutions, from default size to max resolution.
About this tool
This youtube thumbnail grabber finds public thumbnail image URLs for a YouTube video and shows the common available sizes. Paste a standard watch URL, Shorts URL, youtu.be link, embed URL, or plain video ID, then preview max resolution, SD, HQ, MQ, and default thumbnails.
The tool is useful for content audits, design checks, creator workflows, and downloader thumbnail YouTube tasks where you need to inspect the actual image YouTube exposes. It does not bypass private videos, membership content, or copyright rules. Use thumbnails you have permission to reuse, and remember that the max resolution image may not exist for every video.
The lookup is 100% free, runs in your browser, nothing is uploaded, and simply builds public thumbnail image URLs from the video ID. Check each size because YouTube does not provide every resolution for every upload. Use the open button to test each thumbnail before downloading it locally.
