Zoom in on webpages
You can make text and images larger so they’re easier to view.
Make the content larger for all webpages
Choose Safari > Preferences, click Websites, then click Page Zoom.
Select all websites listed under Configured Websites (to select several websites at once, press and hold the Shift or Command key as you click), then click Remove to clear the list.
If you don’t see anything listed under Configured Websites, either you haven’t configured any yet, or you previously cleared the list.
Click the “When visiting other websites” pop-up menu, then choose a larger percentage.
Make the content larger for a specific website
Make all content larger: Choose Safari > Settings for This Website and choose an option from the Page Zoom pop-up menu, or choose View > Zoom In. You can also pinch open on a trackpad that supports gestures. Safari remembers the zoom level when you return to the website (unless you pinch open to zoom).
Make only the text larger: Press Option while you choose View > Make Text Bigger. Safari remembers the text size when you return to the website.
Expand to full-screen view
Click the green full-screen button in the top-left corner of the browser window, or press Control-Command-F. To stop using the app full screen, move the pointer to the top-left corner of the screen, then click the green full-screen button again, or press Control-Command-F.
Use Safari in Split View
Click and hold the green full-screen button in the top-left corner of the browser window, drag the Safari window to the side of the screen you want, then release the button. Select an app that supports Split View on the other half of the screen.
