And you can use the navigation bar at the bottom of the page to set the page to be displayed in Tile or to fit one full page to the window.

Navigating to "View" > "Page Display", you can easily set the desirable page layout for reading your PDF files. For example, you can select a single page view, two page view, two page scrolling, automatic scrolling, etc. Besides, this program also supports a rotating page view in a clockwise or counterclockwise direction.

It offers a wide selection of page zoom levels including "Fit Width", "Fit Visible", "Zoom to Page Level" and many more.

You may also want to go to a certain chapter by clicking the bookmark to jump straight to that point. In that case, you need to take advantage of the bookmark tool. It is also on the left side of the window, but sometimes it is not visible. Then, you need to right-click the button to show the navigation panel.


Actually, "Show/Hide" can also work for rulers, toolbars and menu bars, etc.

Compress PDF

EaseUS PDF Editor can also help you reduce your file size. There are two solutions for you.

To add a sub bookmark, you can cut the bookmark, right-click the other bookmark where you want to insert it, and choose "Paste under Selected bookmark". To delete a bookmark, just select it and then use the recycle bin tool to remove it.


Default PDF Reader

For people who often work with PDFs, you may want to set this great Adobe Acrobat alternative as your default PDF reader. Of course, you can use the Windows solution to set the default reader. But within our program, there is an easier way to do that. Just go to "Help" on the top of the program and click "Set to Default PDF Reader".



With the Print function, you can do more than just print PDF files. When you choose "EaseUS PDF Editor Printer" as the printer, you can take the advantage of "Print in grayscale(black and white)" to turn a colorful PDF into a black and white PDF.


With the "Poster" option under "Page Sizing & Handling", you can split a PDF page into two or more parts.

Please note that you need to click "Print" to generate a black and white PDF or a split PDF.

Create a PDF

Whenever you want to create a new PDF file or even convert images or documents to PDF, you can make use of the "Create" feature.

Convert PDF

This tool can also be used to convert PDFs to other formats. Just click the "Convert" icon and choose the format you like from the drop-down. From there, you can select Bitmap, JPEG, PNG, GIF, and TIFF.

Edit a PDF

This software also comes with a variety of editing options. You can directly hit "Edit" on the toolbar to edit content and add links.


You can choose "Edit Text & Image" to modify the text and images of the original document. If you wish to add text to any part of the page, you can hit "Add Text".

Split Document: Easily split PDF documents by the number of pages, file size, and top-level bookmarks. If you want to split the file into several pages, each of which contains less than 10 pages, then you can split by setting the max pages to 10. The "File Size" mode allows you to split the file and keep each split document under a certain file size. Moreover, after you set the method, you can batch split the files in the same way by clicking "Apply to Multiple".


Crop: Drag a rectangle on the page you want to keep, and then double click inside the cropping rectangle to open the Crop Pages dialog box. In the box, you can customize the selected area.

Add Protection

With this function, you can secure your file with a password or remove a security password.

Add a Password to a PDF

Choose "Protection" > "Encrypt with Password" and you can protect your PDF documents by adding a password to limit access to a PDF. This can also restrict certain features, such as printing and editing. Basically, there are two kinds of passwords that could be used to encrypt the file which is document open password and permission password.


Document Open password: A password is required to enter when opening a PDF file each time.

Permission password: Using a permission password, you can open PDF file without any password, however, a password is required when changing permission settings. Plus, you can restrict printing, editing, signing and copying content in the PDF. And if you opened a document with permissions password, you need to go to "Protection" > "Encrypt with Password" to enter the password first, and then you can start doing the password required actions.


And please note that the two types of passwords cannot be the same.

Remove Password Security

To remove security from a PDF file, you must have the permission and password to do so. If your document is encrypted with permission password, but you forget the password, then you can’t remove security with any PDF editors.


Once you open the PDF, you can forward to "Protection" > "Remove Security" button, type the permission password and then remove password security.

Using this method, you will remove both Document Open password and Permissions password. If you just want to disable permissions password, you can enter the password to go to "Encrypt with Password" to disable and click "OK".

Please note that, changes will be not applied to the document until you save the file again.

Sign a Document

EaseUS PDF Editor also makes it easy to sign documents electronically. This differs from traditional handwritten signatures, as digital signatures often contain additional information, such as the location, date & time of signature and the reason for signing.

To sign a PDF, please choose "Sign" tool from the top toolbar and then select “Place Signature” from the right menu bar. Next, hit "Drag New Signature Rectangle" button, click and drag your mouse to draw a rectangle on the page, and then release your mouse.


If you don't have a digital ID for signing, then you have to create a new ID with this program. To create a self-signed digital ID, choose "New ID" from the dropdown menu of "Sign As" and then select "A new digital ID I want to create now". Hit "Next" to continue and check both of the options when selecting where to store your self-signed digital ID.

If you want to sign and certify your document, please select "Sign & Certify" from the right sidebar and choose the most desirable option you want. The following steps are the same as what was introduced above.
