Draw the composition
Mark the subject, text area, arrows, circles, or any visual relationship that matters to the thumbnail.
SKETCH TO FRAME / 05
Turn a rough sketch into a thumbnail worth reviewing.
Draw the subject, text area, arrows, circles, or composition you have in mind. TubNexa helps turn that rough layout into a polished original thumbnail direction.
For creators who can see the composition before they have the time or tools to finish it.

WHY THIS WORKFLOW
A sketch is often the fastest way to protect the idea before detail takes over.
You do not need to know the final colors, lighting, or typography to communicate a composition. The sketch workflow keeps your placement and visual intention visible while TubNexa develops the image around it.
THE WORKFLOW
From rough premise to a frame worth reviewing.
See the full workflowKeep the important structure
Use the rough image as a layout signal so the generated direction respects the way you want the frame to read.
Review the polished frame
Generate a clean original thumbnail and inspect whether the final image still communicates your first idea.
KEEP THIS CLOSE
The finished image should still feel like your composition
Polish is useful when it makes the original idea clearer, not when it hides the reason you drew the sketch in the first place.
Open the Analyzer01
Mark the largest subject and the intended reading order.
02
Leave safe space for a headline if the thumbnail needs text.
03
Use arrows and circles to communicate relationships, not decoration.
04
Keep the sketch simple enough for the main idea to remain unambiguous.
05
Review the result at small size and refine the layout if the subject gets lost.
QUESTIONS CREATORS ASK
Useful answers before you choose a workflow.
Do I need to be good at drawing?
No. A rough layout with simple shapes and notes is enough to communicate the composition you want to explore.
Can I upload a hand-drawn sketch?
Yes. You can upload a sketch image or use the in-app sketch canvas to define the layout.
Will the generated image keep my layout?
The workflow is designed to use your sketch as composition guidance while rebuilding the image as a polished original thumbnail.
Can I add a headline to the result?
Yes. Thumbnail text can be enabled or disabled in the workspace settings.
READY WHEN THE IDEA IS
Bring the rough version. Leave with a clearer point of view.
No inflated promises. Just a better place to begin.
