Thumbnail Safe Zone Checker
Upload your thumbnail and see exactly which parts of it get covered by player UI — the duration badge, caption overlays, the resume-watching progress bar, and the mobile center play button. Catch hidden text and obscured faces before you publish.

Why this matters
Most thumbnails look great in a design tool but lose key text the second they're rendered inside a real player. The duration badge alone covers roughly 12% of the bottom-right corner — exactly where many editors place a price tag, a result number, or a timestamp.
Safe zones are even more aggressive on mobile and TV apps, where the resume-watching progress bar paints over the bottom 3% of every previously-watched thumbnail in red.
An overlay-based check is faster than designing with grid guides, because the zones reflect actual player UI shapes — not abstract margins.
