Preview YouTube Thumbnails | Boost CTR Before You Publish

Your thumbnail is the single most important factor for winning the click. But too often, crucial text is buried under the timestamp or titles get cut off on mobile.

Preview your thumbnail in the real YouTube environment—Desktop Home, Sidebar, and Mobile layouts—before you hit "Publish."

💡 Key Features

High Click-Through Rates (CTR) come from seeing your design through the eyes of a viewer. - Timestamp Overlay: Ensure faces and text aren't hidden behind the black duration box in the bottom-right corner. - Mobile Readability: Verify your "big text" actually works on a 5-inch screen. - Title Truncation: See exactly where YouTube inserts "..." to ensure your hook words stay visible.

📘 Pro Tips

• Upload & Compare: Drag and drop your image to see it across three distinct layouts instantly.
• Simulate the Feed: Enter your channel name and view count to replicate the true visual weight of the YouTube UI.
• Toggle Dark Mode: Many power users browse in Dark Mode. Check that your colors pop against both light and dark backgrounds.
• Protect the Safe Zone: Keep the bottom-right corner clear of any vital branding or messaging.

🧐 FAQ

Is my image uploaded to a server? No. Processing happens locally in your browser. Your designs stay private and are never transmitted to our servers.

What is the ideal thumbnail size? Aim for 1280x720 pixels (16:9 ratio) under 2MB.

Why does my preview look blurry? Low-resolution uploads will appear pixelated. Always design at 1280x720 or higher for crisp results on high-DPI displays.

🧠 Thumbnail Best Practices

• The Rule of Thirds: Place your subject slightly off-center and leave the opposite side for high-contrast text to create a more balanced, professional look.
• Color Contrast: Use bright, high-contrast colors to stand out against YouTube’s neutral UI.
• Front-Load the Hook: Since titles truncate on most devices, put your most compelling keywords in the first 40 characters.
