OneLoupe: Simple zoom tool

OneLoupe is a free, very simple yet effective tool that will let you stretch and zoom any part of your computer screen.

Installation & Requirements

There is no installation for the application. Simply download and extract the files to a folder of your choice and run the executable file. The application supports every version of Windows from 98 and later as well as Windows Servers 2003 and later.


The interface of OneLoupe is really a simple zoom box. If you click on anywhere while using the magnifier, it hides it but you can open it again from the taskbar. The same goes for right clicking. Right clicking the application’s icon in the taskbar will give you more settings about the application like how you want to close it, what the hotkeys are, if you want it to start with Windows, changing your language and more. You can only modify the window through keyboard and mouse shortcuts.

The mouse wheel can be used to adjust the zoom level. Simply scroll it up and down to adjust it. Keep in mind that higher zoom levels diminish the quality of the image by quite a lot. You can take a picture of whatever the modifier window is on by pressing B. You can also copy the pixel value by pressing P. Both of those things will be copied into the clipboard and from there you can paste them wherever you want like Microsoft’s Paint and then you can save the pictures.

Using the arrow keys will resize the window. Using the up key will increase its height, using the down key will decrease its height and so on. Choosing a number between 1 and 9 will automatically adjust the zoom level to the preset of the number. You can mess around till you find the zoom level you are most comfortable with.  You can also use the +/- icons to adjust the zoom accordingly if you do not have a mouse wheel.
