How to Delete Pages from a PDF on Mac (3 Free Methods)

Maybe you scanned a document and ended up with blank pages. Maybe a 50-page report has 3 pages of boilerplate you don't need. Maybe you accidentally included a page of personal info in a file you're about to share. Whatever the reason, deleting pages from a PDF on Mac is quick and free.

Mac users are spoiled for choice here. The built-in Preview app handles most page deletion tasks, and there are solid free backup options if Preview runs into issues.

Method 1: Mac Preview (Fastest Method)

Preview is the default PDF viewer on every Mac. It can delete pages in about 5 seconds:

Single Page:

Open your PDF in Preview (double-click the file).
Show thumbnails: View > Thumbnails (or Option+Cmd+2).
Select the page you want to delete in the thumbnail sidebar.
Press Delete (or Backspace) on your keyboard.
The page disappears immediately.

Multiple Pages:

Show thumbnails as above.
Select multiple pages:
- Consecutive pages: Click the first page, hold Shift, click the last page.
- Non-consecutive pages: Hold Cmd and click each page.
Press Delete.
All selected pages are removed.

Delete from the Menu:

Alternatively, select the page(s) and go to Edit > Delete from the menu bar. Same result.

Important: After deleting pages, go to File > Export as PDF to save the edited version. Using "Save" modifies your original file. "Export as PDF" creates a clean copy with the deleted pages actually removed (smaller file size).

Method 2: Mac Automator (Batch Delete)

If you need to delete the same pages from multiple PDFs (like always removing page 1), Automator can automate this:

Open Automator (in Applications).
Choose Quick Action as the document type.
Set "Workflow receives current" to PDF files in Finder.
From the library, add Render PDF Pages as Images.
Alternatively, search for PDF actions and build a workflow that removes specific pages.
Save the Quick Action.
Use it by right-clicking PDFs in Finder > Quick Actions > your custom action.

Note: Automator's PDF capabilities are limited compared to dedicated tools. For complex batch operations, use PDFsam or a command-line tool.

Method 3: Free Online Tools

If Preview won't let you delete pages (this happens with some password-protected or form-filled PDFs), use a free online tool:

Using iLovePDF Remove Pages:

Go to ilovepdf.com/delete-pages.
Upload your PDF.
Hover over each page and click the X or trash icon to mark it for deletion.
Or click "Delete" and type page numbers (e.g., "1, 3, 5-7").
Click Delete Pages.
Download the result.

Using PDF24:

Go to tools.pdf24.org/en/remove-pdf-pages.
Upload your PDF.
Click pages to select them for removal.
Click Remove Pages.
Download the cleaned PDF.

Why Preview Sometimes Won't Delete Pages

If the Delete key does nothing, the PDF might be:

Password-protected: You need the password to edit. Enter it when opening the file.
Locked by permissions: The creator may have restricted editing. Workaround: File > Print > PDF dropdown > Save as PDF. This creates an unlocked copy.
A scanned image: Single-page scanned PDFs sometimes behave oddly in Preview. Try an online tool instead.
Opened from a browser: Some browsers open PDFs in their own viewer that doesn't support page deletion. Download the file first, then open in Preview.

How to Delete Pages Without Changing the Original

Best practice: never modify your original file. Here's the safe workflow:

Make a copy of the original PDF (Cmd+D in Finder, or copy and paste).
Open the copy in Preview.
Delete the pages you don't want.
Export as PDF.
Now you have the original intact and a new version with pages removed.

Recovering Accidentally Deleted Pages

If you deleted a page and used Save instead of Export, your original is modified. But there's hope:

Undo: Press Cmd+Z immediately. Preview supports undo for page deletions during the current session.
Revert: File > Revert To > Browse All Versions. macOS keeps version history of files.
Time Machine: If you use Time Machine backup, restore the previous version from your backup drive.
iCloud: If the file is in iCloud Drive, check iCloud.com for previous versions.

The Bottom Line

Open the PDF in Preview, show thumbnails, select pages, press Delete, export as PDF. That's it. For stubborn files, use iLovePDF or PDF24 online. Always export instead of save to keep your original file intact.
