What This YouTube Thumbnail Preview Tool Does
YouTube thumbnails appear differently across devices. A thumbnail that looks perfect on desktop may look cropped, zoomed, or unreadable on mobile and TV. This tool helps creators preview their thumbnail in all major device layouts — Desktop, Mobile, and TV — exactly how real viewers will see it.
Why Preview Your Thumbnail?
- Mobile users may see tighter cropping
- Text may become unreadable on phone screens
- TV interface shows thumbnails much larger
- Helps you optimize for higher CTR (Click-Through Rate)
- Ensures your branding and face are clearly visible everywhere
How to Use the Tool
- Paste your YouTube video URL or the 11-character video ID.
- Select a resolution like Max, HQ, or Default.
- Click Show Preview.
- Scroll through the Desktop, Mobile, and TV previews.

- Clear focus on single subject
