Three ways to generate thumbnails from video

Start from a published video, raw footage, or just a script idea. Thumbmagic meets you wherever you are in your workflow.

Generate thumbnails from any YouTube video

Paste any public link and the AI pulls your video automatically. It detects faces, identifies key moments, and generates thumbnails. Just paste and generate.

Auto generate thumbnails from uploaded video

Upload MP4, MOV, AVI, or WEBM files up to 5GB. The AI extracts frames and generates thumbnails the same way it handles YouTube URLs.

Create thumbnails before you film

Paste at least 100 characters of your script and the AI generates thumbnails based on topic and tone. Plan your visual hook before filming.

Choose from 15+ layout styles

Before/after comparisons, podcast speaker grids, educational layouts with text hierarchy, and headline-forward designs—each built for specific creator needs.

AI-generated backgrounds and objects

Put a camera, controller, or book in your avatar's hand to signal your topic. Describe your scene and the AI generates a matching background.
