Make a thumbnail players can read in one second.

A simple Roblox thumbnail maker workflow

Whether you work in Roblox Studio, an image editor, or an AI-assisted thumbnail maker, the workflow is the same: define the click, compose the scene, then remove anything that competes with it.

1. Start with the right canvas

Use a 16:9 canvas. A 1920×1080 file gives you room to work while matching the shape players already see across Roblox discovery surfaces. Keep important faces, text, and props away from the extreme edges.

2. Give the image one job

Decide what a new player should understand first: a boss fight, a social roleplay moment, a race, or a reward. The main subject should be obvious without reading the title.

3. Design for the small version

Zoom out until the thumbnail is roughly the size of a small card. If the character silhouette disappears, the background is too busy, or the title becomes unreadable, simplify the composition before adding more effects.

4. Export a clean PNG or JPG

Use a descriptive filename such as roblox-horror-game-thumbnail.png, keep the image sharp, and avoid placing important copy inside a crop-safe edge. Descriptive filenames and useful alt text also help image discovery.
