FAQ

What are the best practices for course thumbnails?

The best course thumbnails feature a clear, readable title, a professional color scheme, and visual elements that convey the course topic at a glance. Use high-contrast text, limit yourself to 3–5 words, and include imagery that signals the subject matter — such as icons, diagrams, or relevant visuals. GetThumbAI applies all of these principles automatically.

What is the ideal thumbnail size for online courses?

Most platforms recommend 1280×720 pixels (16:9 aspect ratio) as the standard course thumbnail size. This works for Udemy, Skillshare, YouTube, and most LMS platforms. GetThumbAI outputs images at exactly this resolution in high-quality PNG format, so your thumbnails look sharp on every platform.

How can I make thumbnails that increase course enrollment?

To increase enrollment, your thumbnail should clearly communicate the course outcome — what will the learner be able to do after completing it? Use bold, legible text that highlights the benefit, pick colors that stand out in a course marketplace feed, and keep the design clean and professional. GetThumbAI generates enrollment-focused designs by training on high-converting course thumbnails.

Can I use GetThumbAI for YouTube educational content too?

Absolutely. GetThumbAI is perfect for YouTube tutorials, educational series, and tutorial channels. The AI generates thumbnails optimized for both course platforms and YouTube, so you can maintain consistent branding across all your educational content.
