Why can't I delete pages from a PDF on my Mac?

The PDF is secured. You can check this in Tools > Show Inspector > Permissions. The easiest fix is to "re-print" the file as a new PDF using the File > Print > PDF > Save as PDF workaround.

How do I take one page out of a PDF?

The easiest way in Preview is to use drag-and-drop. Open your PDF and show the "Thumbnail" sidebar. Click the single page you want to extract. Drag that thumbnail from the sidebar onto your Desktop.

How do I delete a blank page that won't delete?

If a blank page won't delete even from the Thumbnail view, it's almost certainly because the file is secured or "flattened." You can go to File > Print... > Select the pages you want to keep > Save the PDF as a new document.

How to Delete PDF Pages in Preview: A Complete Guide

Introduction:

Need to clean up a PDF on your Mac? Removing irrelevant or extra pages in the Preview app can be frustrating when it doesn't work. This guide shows you how to delete PDF pages in Preview, how to fix it when it fails, and a powerful free alternative.

Can You Delete Pages from a PDF in Preview?

Yes, absolutely. This is a common point of confusion. Many users open a PDF, click on a page, press the "Delete" key, and nothing happens. This makes them think that Preview is just a "viewer" and that they can't edit a PDF on a Mac.

The truth is that you can't delete a page from the main document view. You must be in the correct sidebar view, known as "Thumbnails," for the "Delete" command to work. What’s more, Preview can also help you extract pages from PDF on Mac.

How to Delete PDF Pages in Preview: The Step-by-Step Guide

The following is the method to delete pages in Preview. It's simple once you know the steps. Let’s get started.

Step 1: Open Your PDF and Show Thumbnails

Double-click the PDF to open it in Preview.
If you don't see a sidebar, go to the top menu bar and click View > Thumbnails.

Step 2: Select the Pages You Want to Delete

Now that your Thumbnail sidebar is open, please click on the pages you want to remove.

To select one page: Click on the single page thumbnail. It will get a blue highlight.
To select multiple pages in a row: Click the first page, hold the Shift key, and click the last page.
To select multiple separate pages: Click the first page, hold the Command key (⌘), and click each additional page you want to delete.

Step 3: Delete the Selected Pages

To delete PDF pages in Preview, you have two ways to delete:

Press the Delete key on your keyboard.
Go to the top menu bar and click Edit > Delete.

The selected pages will instantly disappear from the sidebar.

Step 4: Save Your New PDF

Deleting the pages only changes the view. The file isn't permanently altered until you save it. So, you should save the changes.

To overwrite the original: Go to File and click Save.
To save as a new document: Go to File > Export as PDF... and give the file a new name.

Troubleshooting: Why Can’t I Delete Pages in Preview? How to Fix It?

Is the "Delete" option greyed out? Is the Delete key doing nothing? This is a very common problem. Here are the reasons why and how to fix them.

❌ Reason 1: You Aren't in Thumbnail View

The Problem: You are clicking on the main, large page in the center of the window, or you are in the "Contact Sheet" view.

How to Fix: Follow Step 1 above. Go to View > Thumbnails, then click the tiny page in the sidebar to select it. The "Delete" option will become available.

❌ Reason 2: The PDF Has Security Permissions

The Problem: The PDF is "read-only" or protected with a password. In this case, you can't edit PDF with Preview.

How to Fix: In Preview, go to the top menu and click Tools > Show Inspector. Click the "Permissions" tab (it looks like a lock). You will likely see that "Modifying" or "Content Extraction" is disallowed.

To unlock a PDF for editing, you can use the Print to PDF feature. It can help you bypass permissions even without knowing the password.

In Preview, go to File > Print...
A print dialog box will appear. In the bottom-left corner, click the "PDF" dropdown menu.
Select "Save as PDF" from this menu.
Rename the file and save it.

Now open the new document, and you can easily delete pages using the Thumbnail method.
