How to zoom in and zoom out in your web browser

There are several ways in which you can optimize the reading experience while using a web browser. One way is to zoom in and make the text, images, and icons bigger on the web pages that you want to read. You may need to do this because your eyes are tired, or the resolution of the screen is not ideal. However, at some point, you may need to zoom out or reset the zoom level to get things back to normal. Here’s how to do all this in Google Chrome, Microsoft Edge, Opera, and Mozilla Firefox:

Quick Steps

  1. For zooming in (making the contents larger), press CTRL together with + (the plus sign).
  2. For zooming out (making the contents smaller), press CTRL together with – (the minus sign).

NOTE: Zooming in and out resizes the entire content of web pages, including images. If you only need to modify the size of the text on web pages without impacting other elements, we have you covered as well with this tutorial: How do I make the text bigger in Chrome and other browsers (Firefox, Edge, Opera, Internet Explorer). You can also increase the screen space available for web pages by using Full screen mode.
