To delete pages from a PDF on Mac, open the file in Preview, show the thumbnail sidebar (View > Thumbnails), select the pages you want to remove, and press the Delete key. Save with Command+S. The pages are permanently removed from the file.
Deleting pages from a PDF is one of the most common document cleanup tasks — removing a blank page at the end of a scanned document, stripping a cover page before sharing, cutting confidential pages before distribution, or trimming unnecessary appendices from a long report. The process is straightforward on every device once you know the right method.
This guide covers every method: deleting pages on Mac using Preview step by step, deleting pages in Preview on a MacBook, removing pages on iPhone, removing pages on Android, and deleting pages free online using Transfonic. Each method is explained with the exact steps and the critical mistakes that cause people to accidentally delete the wrong pages or corrupt their files.

How to Delete Pages from a PDF on Mac — Using Preview
Mac's built-in Preview app is the fastest and most direct way to delete pages from a PDF without installing any additional software. Preview comes pre-installed on every Mac and supports permanent page deletion with full page-level control.
This method is documented in Apple's official Preview support guide, which covers page management in Preview, including deletion, reordering, and extraction:
Step-by-Step: Delete Pages from PDF in Preview on Mac
1. Open your PDF in Preview — double-click the file or right-click and choose Open With > Preview
2. Show the thumbnail sidebar: go to View > Thumbnails, or press Option+Command+2
3. In the sidebar, click the thumbnail of the page you want to delete
4. To select multiple pages: hold Command and click individual thumbnails for non-consecutive pages, or hold Shift and click for a consecutive range
5. Press the Delete key on your keyboard — the selected pages are removed instantly
6. Save the file with Command+S — the deletion is saved permanently in the file
The entire process takes under 30 seconds for a standard document. There is no confirmation dialogue — pressing Delete removes the pages immediately. If you delete the wrong page by mistake, press Command+Z immediately to undo before saving.
Critical Warning — Save Behaviour in Preview
Preview uses auto-save on macOS. This means changes, including page deletions, may be saved to the file automatically without you pressing Command+S. If you delete pages and then close the file, Preview may save the changes even if you click 'Don't Save' in some macOS configurations. To be safe, always keep a backup copy of your original PDF before deleting pages in Preview.
How to Delete Multiple Pages at Once in Preview
To remove numerous random pages — say pages 2, 5, 8 and 12 from a 15-page document — press and hold Command and click on the thumbnails in the sidebar to prepare your pick, then press Delete. All selected pages are deleted in one action. For ranges of pages — say, pages 3–7 — click the first thumbnail, hold Shift down and click the last thumbnail in the range and hit Delete.
How to Delete All Pages Except Specific Ones
If you need to keep only a few pages from a large document — for example, extracting pages 4 and 7 from a 20-page file — it is faster to use extraction rather than deletion. Use Transfonic's PDF Split tool to extract the specific pages you want to keep, rather than individually deleting all the pages you do not need.
How to Delete Pages from PDF in Preview — Common Problems and Fixes
Problem: Delete Key Does Nothing in Preview
If pressing Delete does not remove pages, the thumbnail sidebar may not be focused. Click directly on a page thumbnail in the sidebar first to make sure it is selected — the selected thumbnail should show a blue highlight border. Then press Delete. If the issue persists, try Edit > Delete from the menu bar instead of the keyboard shortcut.
Problem: PDF Is Locked and cannot Be Edited
Certain PDFs are secured by the document creator and editing functionalities, such as page deletion, will be restricted. If you see a locked padlock icon in Preview or the option to delete is greyed out for your PDF, it means that the PDF has permission restrictions. You would have to get the unrestricted copy from its creator or utilise a PDF tool that could unlock it, but of course, you would first have to provide the password established by the owner.
Problem: Preview Is Saving Changes Automatically
Preview may save your changes to your PDF without asking because of macOS's auto-save functionality. Note: If you delete pages and close the file, the changes are permanent. To undo the damage, check Version History right away: open File > Revert To > Browse All Versions in Preview. Version Snapshots—macOS saves snapshots of versions and lets you restore to an earlier version of the document.
Problem: Deleted Pages Reappear After Saving
This is very rare and can happen only with some encrypted or non-standard PDFs. If pages you remove come back after saving, the PDF may be too complicated for Preview to change in the correct way. This tool works best with these PDFs; use Transfonic — PDF Delete Page instead because it supports a wider variety of PDF structures reliably.

Transfonic's PDF Delete Page tool handles page deletion directly in your browser — no account, no installation, no cost. This is the most reliable approach for PDFs that Preview struggles with, for Windows users, and for anyone who prefers not to modify their local files directly:
7. Open Transfonic's PDF Delete Page tool in your browser
8. Upload your PDF by clicking the upload area or dragging and dropping the file
9. Your PDF opens with a full-page thumbnail view
10. Click the thumbnails of the pages you want to delete — selected pages are highlighted
11. Review your selection carefully before proceeding
12. Click Delete Pages to remove the selected pages
13. Preview the result to confirm the correct pages were removed

Files are processed securely in the browser using Mozilla's PDF.js rendering technology and deleted automatically after download. The downloaded PDF has the selected pages permanently removed and opens correctly in any PDF viewer.
How to Delete Pages from a PDF on iPhone
Method 1: Files App — Quick Page Removal
iOS 16 and later added basic PDF page management to the Files app, making it possible to delete pages directly on iPhone without any additional apps:
15. Open the Files app and locate your PDF
16. Tap the PDF to open it
17. Tap the page icon in the bottom toolbar to see all pages
18. Long-press the thumbnail of the page you want to delete
19. Tap Delete from the context menu that appears
20. The page is removed — tap Done to save
Method 2: Books App Workaround
On older iOS versions without the Files app page deletion feature, open the PDF in the Books app, tap and hold a page thumbnail in the page overview, and look for a delete option. This method works inconsistently across iOS versions and is less reliable than the Files app approach on iOS 16 and later.
Method 3: Browser-Based Tool in Safari — Most Reliable
For consistent results on any iPhone model and iOS version, open Transfonic's PDF Delete Page tool in Safari. The responsive mobile interface works cleanly on iPhone — upload your PDF, select the pages to delete, remove them, and download the updated file directly to your device. This approach works identically regardless of iOS version.
How to Delete Pages from a PDF on Android
Android does not have a built-in PDF page deletion tool. Google Drive can view PDFs but does not support page editing. The most reliable free approach on Android is a browser-based tool:
21. Open Chrome on your Android device
22. Navigate to Transfonic's PDF Delete Page tool
23. Tap the upload area and select your PDF from local storage, Google Drive, or Downloads
24. The PDF opens with page thumbnails
25. Tap the pages you want to delete to select them
26. Tap Delete Pages
27. Download the updated PDF — it saves to your Downloads folder automatically
The downloaded file has the pages permanently removed and displays correctly in any Android PDF viewer. This approach works on all Android versions and does not require installing any additional apps.
How to Delete Pages from a PDF on Windows
Windows does not have a built-in PDF page deletion tool. Microsoft Edge can view PDFs, but does not support page removal. The most reliable free approach on Windows is the same browser-based method:
Open Transfonic's PDF Delete Page tool in Chrome, Edge, or Firefox on Windows. Upload your PDF, select the pages to remove, delete them, and download the updated file. No software installation, no account, works on any Windows version including Windows 10 and Windows 11.
Delete vs Extract vs Split: Choosing the Right Operation
Operation | What It Does | Original File | Use When |
Delete pages | Removes pages permanently from the document | Modified — pages gone | You do not need the removed pages at all |
Extract pages | Copies specific pages into a new file | Unchanged — original intact | You want a subset, but also need the full original |
Split PDF | Divides the document into multiple separate files | Replaced by multiple output files | You need multiple separate sections |
Delete is the right choice when you want to permanently remove pages from a document — cleaning up a scan, removing a confidential page before sharing, stripping a blank back page before distribution. If you are not sure whether you will need the removed pages again, extract them into a separate file first, then delete them from the original. Extraction preserves your options.
The behavior differences between deletion, extraction, and splitting are defined by the PDF Association's page management specification — the technical standard that all compliant PDF tools must follow when modifying page content and structure.
Real-World Use Cases for Deleting PDF Pages
Removing the blank last page from a scanned document — scanners frequently capture a blank reverse page. Delete it before sharing to keep the file clean
Stripping a cover page before internal distribution — the full document with cover is the final deliverable, but internal teams need the content pages only
Removing confidential pages before sharing — delete sensitive pages from a report or contract before sending to external parties
Cleaning up a merged PDF — after merging multiple documents, separator pages, duplicate pages, or unwanted sections can be deleted from the combined file
Removing outdated appendices — delete appendices or addenda that have been superseded without recreating the entire document
Trimming a PDF for email — remove unnecessary pages to reduce file size before attaching to an email with size limits
Deleting test pages from a form submission — remove header or instruction pages before archiving a completed form
What Happens to Page Numbers After Deleting Pages
When you delete pages from a PDF, the remaining pages do not automatically renumber. If your document had visible page numbers embedded in the content or footer — for example, a report with 'Page 5 of 20' in the footer — those numbers will now be incorrect after deletion.
There are two approaches to handling this:
Remove and re-add page numbers — use a PDF page number tool to strip the existing numbers and add fresh sequential numbers to the updated document
Accept the gap — for internal documents where visual page numbers are not critical, the gap in numbering is acceptable. PDF viewers display pages sequentially, regardless of the embedded page number text
If you need to re-number the document after deletion, Transfonic's PDF Add Page Number tool adds clean page numbers to the updated document as a final step.
Common Mistakes When Deleting Pages from PDFs
Not keeping a backup before deleting: always keep a copy of the original. Deleting pages is permanent and cannot be undone after saving in most tools
Deleting in Preview without checking auto-save: macOS auto-save can save deletions automatically. Keep a backup before making changes in Preview
Selecting the wrong pages — always double-check your page selection before confirming the deletion. Page numbers in the sidebar may not match the displayed page numbers in the document if the PDF has a non-standard page numbering scheme
Not reviewing the output — always open the downloaded or saved PDF and scroll through every page to confirm only the intended pages were removed
Forgetting to update page numbers — if the document has embedded page numbers in headers or footers, re-number the document after deletion
Deleting when extraction is needed — if you might need the removed pages later, extract them into a separate file first before deleting from the original
Related PDF Tools for Complete Document Management
PDF Split — divide a PDF into multiple separate files by page range or specific pages. Use when you need separate output files rather than just a reduced document. See our guide on how to split a PDF.
PDF Extract Page — copy specific pages into a new file while keeping the original unchanged. Use this before deleting if you want to preserve the removed pages separately.
PDF Merge — combine multiple PDFs after editing them individually. Use to reassemble a document after deleting pages from separate sections. See our guide on how to merge PDF files.
PDF Reorder Page — rearrange the remaining pages after deletion if the page order needs adjustment.
PDF Add Page Number — re-number the document after deleting pages to restore clean sequential pagination. See our guide on how to add page numbers to a PDF.
PDF Rotate Page — rotate any misoriented pages in the document alongside deletion. See our guide on how to rotate a PDF.
Conclusion — Delete Pages from Any PDF in Seconds, Free, Any Device
Deleting pages from a PDF is a quick operation once you know the right method for your device. On Mac, Preview handles it natively in under a minute — show the thumbnail sidebar, select pages, press Delete, save. On iPhone, the Files app works on iOS 16 and later. On Android and Windows, a browser-based tool delivers consistent results without any software installation.
The one rule that applies across every method: keep a backup of your original PDF before deleting pages. Deletion is permanent. Auto-save on macOS means changes can be written to the file faster than you expect. A backup copy costs nothing and prevents an irreversible mistake.
