YouTube Thumbnail Safe Area Checker
Load a thumbnail and see whether the timestamp badge and mobile UI overlays cover your key text or captions
Drop your finished YouTube thumbnail onto a virtual canvas and preview it with the same overlays viewers actually see — the video duration badge and the progress bar layer on both mobile and desktop — so you can catch covered text or graphics before you ever upload.

How to use
- Drag and drop the thumbnail you want to check (16:9 recommended) to upload it.
- Turn on the simulated overlay layers, including the timestamp badge position.
- Check that your headline text or the subject's face isn't buried under the bottom-right badge or other overlays, then adjust your layout accordingly.
FAQ
- Which areas of a thumbnail should I keep clear?
- On mobile, the duration badge (e.g., 10:15) is always pinned to the bottom-right corner of the thumbnail. Any text or logo you place there will be covered and unreadable, so keep that corner free of anything important.
- Does the time badge appear in a different position or size on desktop versus mobile?
- Yes — on the mobile app the badge shows up relatively smaller, and its exact position can shift slightly depending on screen size. Switching between the desktop and mobile overlays in this tool lets you confirm your layout stays safe in both environments.
