About
Renderbux is a free Roblox thumbnail maker that runs in the browser. Type a Roblox username and your real avatar loads in 3D — the same outfit, accessories, and face you wear in-game. Pose the rig, set lights and a skybox, and export a PNG.
Use it for:
- Roblox experience thumbnails at 1920×1080
- Game icons at 512×512
- YouTube thumbnails at 1280×720 or 1920×1080
- Discord / TikTok / YouTube profile pictures
The difference vs AI thumbnail tools (ForgeGUI, RoVisuals, VizzBees and similar): those generate an invented Roblox-looking character. Renderbux poses the avatar you already have. The difference vs Blender: no rig import, no add-ons, no desktop install. It works on a phone.
Posing, lighting, scene setup, and the community pose gallery are free and stay free. PNG export is metered — 1/week signed out, 5/week on a free account (720p, watermark). Renderbux Pro is $9.99/month or $90/year for unlimited renders, 1080p/2K/4K, no watermark, and transparent backgrounds.
R6 and R15 both work. Renderbux is independent and not affiliated with Roblox Corporation.
