How to Increase or Decrease the Zoom Level in macOS Safari

Sometimes when I’m viewing an article (usually involving patent images) in Safari, it’s hard to view an entire image. However, you can increase or decrease the zoom level of images (and text) when viewing web pages in the macOS web browser. 

When viewing a picture or text, press Command and the + (plus) or – (minus) keys. Alternately, you can click on View in Safari’s menu bar and select Zoom In or Zoom Out.

You can even add zoom buttons to Safari’s toolbar. To do so, right-click (or Control-click) on a space in the Safari toolbar and click Customize Toolbar. Click and drag the Zoom buttons in the dropdown to the are you clicked on the toolbar. Click Done to finish.

Also cool: if you wish to keep images at the same size and only adjust web page font size on the fly, press Option-Command and the + or – keys. You can also hold down the Option key and click on View in the Safari menu bar. This changes the Zoom options to “Make Text Bigger” and “Make Text Smaller.”

The web browser will “remember” your zoom wishes and preferred font size settings until you clear your History. If you want to do that, open Safari, select Clear History, and click the Clear History button. 

But, wait!, we’re not done. You can also set the zoom level for a website of your choosing. Once you’ve set up the zoom level for a specific webpage, Safari applies it automatically whenever you view it. Here’s how to set this up:

Go to the site.

Under the Safari menu, click Settings for This Website. You’ll be presented with a variety of options from which to choose, including setting the page zoom percentage.
