Download LumiZoom
LumiZoom is a screen enlargement utility for Windows computers. It magnifies the whole desktop, including the Start menu and other system menus, at a single consistent scale. Magnification follows the mouse pointer, and a coloured marker can be drawn around the pointer for visibility. Zoom level, tracking behaviour, and the global shortcut are set by the user. The program starts with Windows by default and remains available from the notification area.
The application is intended for people with low vision and for older users who require larger on-screen text. It avoids a separate magnifier panel and keeps the magnified image aligned with the actual desktop, so menus and dialogs open in their normal positions. An Esc key command returns the display to normal scale at once. The interface offers light and dark themes and three text sizes.
LumiZoom operates entirely on the local computer. It contains no telemetry, no analytics, no advertising, and no online account requirement. It is distributed under the MIT License and targets 64-bit Windows 10 and Windows 11. Installation requires administrator permission, and the installer includes everything needed to run the program without a separate framework installation.
