How to Change Roblox Game Thumbnail

Updated October 23, 2026

Your game thumbnail is the primary visual hook that determines whether players click into your experience or scroll past. A dynamic, high-contrast thumbnail drives player conversion and social engagement. Here is how to update your game thumbnail.

Step 1: Prepare a 1920×1080 Thumbnail

Roblox recommends an image resolution of 1920×1080 pixels (16:9 aspect ratio) in PNG or JPG format. Keep key characters, action poses, and text centered so they remain legible on mobile phone screens. Generate custom high-converting action thumbnails in seconds with the Roblox Thumbnail Maker.

Step 2: Upload via the Creator Dashboard

1 Navigate to create.roblox.com and log in with your developer account.
2 Click Creations and select the experience you want to update.
3 In the left navigation menu, click Places under Basic Settings, then click your starting place.
4 Select Thumbnails from the left sidebar.
5 Under Media, click Choose File and select your 1920×1080 image.
6 Click Upload Image to submit it to moderation.

Uploading image thumbnails is completely free. You can add up to 10 media items (including YouTube video trailers for 500 Robux each) to display in the experience carousel.

Step 3: Rearrange and Feature Your Best Artwork

Once your thumbnails pass moderation, drag your most compelling visual to the first position. The first thumbnail serves as your primary search result image across the Roblox Discover page and player home feeds.
