What is a course thumbnail?
A course thumbnail is the cover image displayed on course marketplaces, landing pages, and social media when someone discovers your online course. Think of it as the "book cover" for your educational content — it's the very first visual impression a potential student gets, and it plays a critical role in whether they click to learn more or scroll past.
Great course thumbnails combine bold typography, relevant imagery, and a professional portrait of the instructor to signal quality and build trust before a single lesson has been watched.
Why does your course thumbnail matter?
Research consistently shows that visual content captures attention faster than text. A well-designed course thumbnail can dramatically influence your click-through rate (CTR) and, ultimately, your enrollment numbers. Here's why it matters:
- First impressions count — Students browsing a catalogue will make a snap judgment based on the thumbnail. A polished image signals a professional course.
- Higher CTR — Thumbnails that feature a human face alongside clear course titles have been shown to achieve significantly higher click-through rates.
- Brand recognition — Including your face or logo in every thumbnail creates visual consistency across your catalogue, making your courses instantly recognizable.
- Social sharing — Compelling thumbnails appear as Open Graph images when links are shared on LinkedIn, X, and Facebook, multiplying organic reach.
How to create a course thumbnail with this tool
- Enter your course subject — Tell the AI what your course is about (e.g. "cryptocurrency investing" or "watercolour painting"). This gives the model creative direction for colours, imagery, and composition.
- Add your course title — Type the exact title you want displayed on the thumbnail. The AI will incorporate it into the design.
- Upload a profile photo (optional) — Drag and drop a clear, well-lit headshot. The AI will blend your portrait into the design for a personal touch. This is especially important for building trust and increasing CTR. Adding a logo or brand image can also work well for business courses.
- Click "Generate thumbnail" — Within 15-30 seconds you'll receive a 4K, 16:9 thumbnail ready to download and use on any platform.
Tips for an effective course thumbnail
- Use a high-quality headshot with a neutral or solid background for the best compositing results.
- Keep your course title concise — shorter titles read better at small sizes.
- Be specific with the subject field — "beginner Python programming" gives the AI more to work with than just "coding."
- Generate a few variations and A/B test them to find the thumbnail that drives the most clicks.
