There are many PDF files that contain small words or images that make it very hard to view, therefore many readers have asked how to zoom in a PDF. The task can be easy as long as you have the right tools. In this article, I will teach you how to zoom PDF on Mac and Windows step by step.

Part 1. How to Zoom a PDF on Mac OS X (El Capitan Compatible)

With iSkysoft PDF Editor Pro for Mac, you can easily zoom in a PDF file on Mac without any trouble. Even if you are not interested in using this function at this time, it is still a good idea to learn. With the Zoom option available, you are able to enlarge or reduce the PDF page sizes whenever you want. This tool has powerful PDF editing and converting features, enabling you to easily make changes on your PDF files and convert them to other document format you prefer.

What You Will Need:

A Computer;
iSkysoft PDF Editor Pro for Mac

Time Required:

Around 1 min



Step 1. Open Your PDF Files

Open your PDF editing program and then import the PDF file that you want to view. Simply click the "Open File" button and the PDF editing program will open automatically.

Step 2. Start to Zoom PDF on Mac

Once you have your file opened, you may then begin to zoom in on your PDF file. Go the "View" tab on the tool bar at the top of the page and open "Zoom". Under this menu, you will find multiple radio buttons that you can choose from to begin viewing.


Page Display: Your first choice is page display that gives you the options of picking single, continuous, facing (like a book) or facing continuous. Sometimes just changing the page will make the PDF on Mac much more readable.

Zoom Option: After you have decided on the page layout that you want, the next options are the zoom option. The four choices are fit to width of screen, fit to height, fit page to window, and the zoom option. The zoom option will enable you to choose from 10% to 600% in size. Depending on the zoom percentage, you may need to scroll across and down the page to find the item you are searching for. On a wide screen monitor, up to 200% will allow viewing of the entire page without scrolling left or right.

A Note to Remember: the entire document will increase by the percentage you choose so you do not need to change settings often. In addition, the zoom function does not change the document properties, and will revert back to normal as soon as you close the window.

Part 2. How to Zoom PDF on Windows (Windows 10 Compatible)

As today you will get a recommendation for a software tool with advanced features. This is the iSkysoft PDF Editor Windows software and you can use it to zoom easily without trouble.

What You Will Need:

A Computer;

Time Required:

Around 1 min



Step 1. Open up the Targeted PDF Files

Start by opening the PDF Editor tool and then the PDF that you would like to view. Click the Open button to browse for the local folder.

Step 2. Begin PDF Page Zoom

After the PDF file opens, you can start to zoom. Click on the "View" tab to get started. You should see multiple buttons on the tab, so feel free to choose the ones that you need for viewing. There is the page display option that will allow you to choose single, facing, continuous or facing continuous for easy viewing.

Once you decide on the layout that you want for the page, you can move on to "Zoom" to choose the viewing percentage. You might have to scroll down and across the PDF page, based on the zoom percentage that you choose, in order to locate the desired item.

Things to Remember:

Note that a wide-screen monitor can allow you to apply the required settings to view an entire page and you don't have to scroll to the right or left side. It's also worth mentioning that you can increase the entire document with the chosen percentage without having to change the settings on a regular basis. Besides that, the zoom function will not modify the document properties, so it can go back to the normal position once the window closes.
