Image Extender is an open-source web app for AI outpainting and 2D game-art generation. It lets users extend an image in any direction while using Poisson blending to reduce visible seams between the original and generated areas. The app uses Gemini image models through OpenRouter and keeps the user’s OpenRouter key in the browser. It includes a best-of-three variant picker so users can choose the cleanest extension result. Beyond outpainting, it provides workspaces for parallax backgrounds, autotile sets, animated sprite sheets, and transparent prop sprites. It is useful for creators who need fast visual expansion, game-ready assets, or browser-based AI art workflows without a large local setup.
