Browser Zoom lets you enlarge or reduce the view of a webpage. Unlike changing font size, zoom enlarges or reduces everything on the page, including text and images. The following information applies to all modern browsers including Internet Explorer, Firefox, Chrome, and Safari. You can zoom from 10% to 1000%.
If you have a mouse with a wheel, hold down the CTRL key, and then scroll the wheel to zoom in or out.
From the keyboard you can increase or decrease the zoom value in 10% increments. To zoom in, press CTRL+PLUS SIGN (+). To zoom out, press CTRL+MINUS SIGN (-). To restore the zoom to 100%, press CTRL+0.
