Generate your Roblox game thumbnail with AI
On Roblox, the thumbnail decides the click. Builblox's thumbnail studio turns a description — or a starting image — into icons at the right size, in the style that works on the platform: expressive characters, saturated colours, readable text.
From a description or from an image
You write the scene you want: "two avatars running from an explosion, title in yellow". Or you upload a capture of your game and the AI turns it into a finished thumbnail. You can chain variants until the one you like.
Roblox-sized, ready to publish
Thumbnails come out at the dimensions Roblox expects for the icon and experience images. You download in one click and upload them in the Creator Hub. Each project keeps its thumbnails: yesterday's are in the left column.
Included in every plan
The thumbnail studio is part of Starter, Pro and Studio. It spends credits like building does, at a far lower rate than a whole game.
Frequently asked questions
Can I use my own character?
Yes: upload an image of your avatar or your game as the starting point and describe what you want around it.
