Download Magpie – Game Window Upscaling Tool for Windows

Magpie is a lightweight, open-source Windows utility that upscales any game or application window to fill your screen using advanced scaling algorithms. It is designed for gamers who want to play older, low-resolution games at full-screen quality without the blurriness of standard stretching.

Unlike generic upscalers, Magpie supports a wide range of modern and classic algorithms including Lanczos, xBR, FSRCNNX, Anime4K, and AMD FSR — giving you crisp, artifact-free upscaling tailored to the type of content you are viewing. It works as an overlay that captures the target window and renders it upscaled, without modifying the game itself.

Magpie is especially popular among retro gaming fans and emulator users who want sharp visuals on high-resolution displays. The tool is lightweight, runs in the system tray, and can be activated with a keyboard shortcut at any time.
