Use any thumbnail as a style reference
Seen a layout that works in your niche? Grab the thumbnail, drop it into your project and ask for that style for your own video — an original design, not a copy.
Learn from what works — without copying
Studying successful thumbnails in your niche is one of the fastest ways to improve. ThumbSpark lets you use them as style references: the model follows the layout, colour palette, lighting and typography, while the subject, text and people are your own.
Style references are explicitly marked as style-only, so the model is instructed not to reproduce faces or subjects from them.
How to do it
- 1
Grab the thumbnail
Paste a video link into the YouTube thumbnail downloader — or the one inside the app.
- 2
Add it as a reference
Drag it into the chat, save it to an agent, or keep it in a reference library bucket.
- 3
Describe your video
Tell the agent what your video is about and that you want this style.
- 4
Generate your version
Approve the proposal and get an original thumbnail in that style.
Tip: Combine elements: the layout of one reference, the colours of another and your own face as a character.
Frequently asked questions
Is it legal to use another thumbnail as a reference?
Using a thumbnail for inspiration on style is common practice; copying someone’s image, face or artwork is not. ThumbSpark creates a new image and instructs the model not to copy subjects. You’re responsible for what you publish.
