Questions
What makes a good Roblox thumbnail?
A real moment from your game, from a good angle, that says what players do. Most people see it small, on a phone, so a short title and one clear subject beat a busy picture.
Can I put text on a Roblox thumbnail?
Yes, but keep it short and about the game. Roblox's rules for video thumbnails ban ads and claims like "50% off" or "Free UGC!", and that's a sensible rule for pictures too. Every thumbnail has to pass moderation.
Where should the title go?
Near the top or in the middle. Roblox says to keep anything important away from the bottom, where the player count can cover it. That's why this tool doesn't offer the bottom.
What size does it make?
1920×1080 for a thumbnail, which is what Roblox recommends, or 512×512 for an icon. See every size on the image sizes page.
Is there a watermark?
No. There's no watermark and no account, and it's free.
Is my picture uploaded anywhere?
No. It all happens in your browser, and your picture never leaves your computer.
