The "Timestamp Trap"

One of the most common mistakes creators make is placing important text or logo elements in the bottom-right corner of their thumbnail.

YouTube automatically overlays a black timestamp badge (e.g., "10:24") in that corner, which can completely block your content. This tool helps you visualize that overlay instantly.

Standing Out

Your thumbnail doesn't exist in a vacuum. It competes with dozens of other videos. By seeing your design "in context" surrounded by other videos, you can better judge if your colors pop or if your text is readable.
