Most web browsers will allow you to simply enlarge and reduce text and image sizes through the options in the menu bar, or by pressing "Ctrl +" and "Ctrl -" or other keyboard combinations (see browsing the Web by keyboard for more information on keyboard commands). However, these changes are often temporary and may be lost when you open a new browser window or the next time you start your web browser. To make text and images appear larger by default in your web browser, you need to modify the settings of the web browser.
