Notable Information about the Screen Magnifier:

  • Why? The built-in screen magnifier in Windows operating systems is often cumbersome to use and lacks intuitive design, including the newer Windows 7 version. OneLoupe offers a different experience, providing a user-friendly interface that is significantly more convenient than the native system solution.

  • Design: OneLoupe features a simple yet comfortable design that prioritizes ease of use. The main goal was to develop a straightforward screen magnifier (magnifying glass) that allows anyone to easily zoom in on and select any area of the screen.

  • Usability: To start using the program, simply launch it. The first time you run it, a license screen will appear. OneLoupe is free to use, and the license information is displayed only on the first launch per PC. The zoom factor can be quickly adjusted using the "+" and "-" buttons, and the window size for the magnified area can be fine-tuned using the arrow keys. To cancel or exit the screen magnification, simply click the left mouse button or close the magnification window with the "ESC" key.

OneLoupe can be used effectively across multiple monitors, thanks to its support for multi-monitor setups. It has minimal impact on system resources, ensuring smooth performance. Notably, it offers convenient screenshot functionality to capture the magnified area with the "B" key and pixel query capability with the "P" key. Both can be easily accessed from the clipboard by using the Ctrl+C keyboard shortcut for copy and paste operations.


OneLoupe does not require installation. Simply place it on the desktop for immediate access, or copy it to a USB stick for portable usage. This ensures that you can enjoy the full functionality of the screen magnifier while on the go or when using different computers or laptops.

Functionality Overview:

  • Adjust the magnification area/window size using the arrow keys (left, right, up, down).
  • Fine-tune the area in single steps by holding down the Shift key.
  • Change the zoom factor:
    • Using the "+" and "-" keys
    • With the mouse wheel
    • Directly enter the factor using the number keys (1-9).
  • Copy the current pixel value as a hexadecimal code to the clipboard with the "P" key.
