Technical Constraints & Limitations

- Only publicly viewable YouTube video covers are retrievable; private or geoblocked streams depend on CDN availability.
Frequently Asked Questions
Is it legal to download YouTube thumbnails?
Yes. YouTube thumbnails are publicly served image assets intended for feed display and sharing across platforms. You can download them for editorial reference, fair-use analysis, or archiving your own uploaded content.
Does this tool work with YouTube Shorts?
Yes. You can paste standard watch links, youtube.com/shorts/..., youtu.be/... shortened links, or livestream links.
Why does maxresdefault occasionally show a gray placeholder for older videos?
Before 2012, YouTube did not generate 1280×720 "maxres" covers for standard definition (480p) uploads. If a video is very old, choose the High Quality (HQ 480×360) option instead.
