FAQ

What size should a Roblox thumbnail be?

Roblox recommends a 16:9 image, ideally 1920×1080 pixels. We export at that size for a direct Creator Hub workflow.

Can I add my game's title text?

Yes — text is rendered as an editable layer on the canvas, so you can reword or restyle it before exporting.

Is this cheaper than commissioning an artist?

Commissions typically run $20–50 per thumbnail. Here a thumbnail costs a few credits; you start with 15 free.

Do I own the thumbnail?

Yes. Commercial use is permitted, subject to our Terms and the rules of the platform where you publish it.
