About This App
This tool helps you design better thumbnails by showing you the 'safe zones' where your content is unlikely to be covered by YouTube's interface. By uploading your design, you can toggle guides to see where the timestamp appears or how the image might be cropped on different screens. This ensures your key visual elements are always clear and clickable, no matter how a viewer sees it.
