🚀 Why You Need Custom Thumbnails

YouTube reports that 90% of the best-performing videos have custom thumbnails. For bloggers, a featured image is what appears when your link is shared on Facebook or Twitter. A generic image gets scrolled past; a designed thumbnail gets clicked.

Key Features

• Dual Mode: One click to switch between "Blogger Standard" (800x450) and "YouTube HD" (1280x720) dimensions.
• Image Filters: Upload your own photo and use the sliders to adjust brightness and contrast. No need to edit the photo beforehand.
• Smart Text Overlay: We automatically add a dark overlay behind your text so it remains readable even on busy backgrounds.

How to Design a High-CTR Thumbnail

1. Colors: Use high-contrast colors like Yellow on Black, or White on Red.
2. Text: Keep it short. Don't repeat your title word-for-word. Use a teaser phrase (e.g., "The Secret Revealed" instead of "How to do X").
3. Faces: If you are making a YouTube thumbnail, include a face showing emotion (surprise, joy, anger). Humans are wired to look at faces.
