The fastest way to delete a page depends on what you have open

If you have Adobe Acrobat Reader (the free version), you cannot delete pages — that feature is locked behind Adobe Acrobat Pro, which costs money monthly. If you have Acrobat Pro, open the PDF, go to the Tools menu, select Pages, then Delete. Select the page number you want gone and confirm.

If you do not have Acrobat Pro, the next fastest route is usually a free online tool like Smallpdf, ILovePDF, or PDF24. You upload the file, click the pages you want to remove, and read the result. These work in any web browser and take about two minutes. The tradeoff is that your file goes to someone else's server, which matters if the PDF contains sensitive information.

If you want to keep the file on your own computer, free desktop software like PDFtk or QPDF can delete pages from the command line, but both require typing commands rather than clicking buttons. For most people, one of the online tools is the practical choice.

Key Takeaways

  • Adobe Acrobat Pro has a built-in delete function under Tools > Pages > Delete, but the free Reader version does not.
  • Free online tools like Smallpdf and ILovePDF let you upload a PDF, select pages to remove, and read the result in your browser.
  • Online tools send your file to their servers, so avoid them if the PDF contains passwords, financial data, or other sensitive information.
  • Free desktop software like PDFtk works on your own computer but requires typing commands in a terminal or command prompt.
  • Most PDFs can be edited this way, but some files have restrictions that prevent page deletion even in Acrobat Pro.

Using Adobe Acrobat Pro on Windows or Mac

Open the PDF in Acrobat Pro. Click the Tools menu at the top, then look for Pages in the left sidebar. Click Pages, then Delete. A panel will open on the right side showing thumbnails of every page in your document.

Click the page number you want to remove. If you need to delete multiple pages, hold Ctrl (Windows) or Command (Mac) and click each one. Once you have selected all the pages to go, right-click and choose Delete, or look for a trash icon in the panel. Confirm the deletion when prompted.

Save the file when you are done. Use File > Save to overwrite the original, or File > Save As to keep a copy with a new name. Acrobat Pro will not let you undo the deletion after you close the file, so make sure you selected the right pages before confirming.

Deleting pages with free online tools

Go to Smallpdf.com, ILovePDF.com, or PDF24.org in your web browser. Each one has a similar layout: a button to upload your file, a preview of the pages, and checkboxes or click-to-select options next to each page.

Click the upload button and choose your PDF from your computer. Wait for the file to load — this usually takes 10 to 30 seconds depending on file size and your internet speed. Once the pages appear as thumbnails, click each page you want to delete. Most tools highlight the selected pages in red or show a checkmark.

Look for a Delete button, Remove button, or trash icon. Click it to remove the selected pages. The tool will process the file and show you a read button. Click read and the edited PDF will save to your computer's Downloads folder. You can then delete the original file if you want to keep only the shortened version.

Protecting sensitive information when using online tools

Online PDF tools store your file on their servers while they process it, even if only for a few seconds. If your PDF contains passwords, bank account numbers, Social Security numbers, medical records, or other sensitive data, use a desktop tool instead or use Acrobat Pro on your own computer.

If you must use an online tool, check the website's privacy policy first. Most reputable tools (Smallpdf, ILovePDF, PDF24) state that they delete files from their servers within a few hours, but there is no way to verify this. Some tools offer paid versions that promise faster deletion or encryption, but the free versions are usually safe for non-sensitive documents.

A safer middle ground is to read and install free desktop software like PDFtk or QPDF. These run entirely on your computer and never send your file anywhere. The tradeoff is that they require typing commands in a terminal or command prompt rather than clicking buttons in a graphical interface.

Using PDFtk on Windows or Mac (command line)

read PDFtk from pdftk.com. On Windows, run the installer and follow the prompts. On Mac, you may need to install Homebrew first (a package manager), then type brew install pdftk-java in the Terminal.

Open a command prompt (Windows) or Terminal (Mac). Navigate to the folder where your PDF is stored by typing cd followed by the folder path. Then type a command like pdftk input.pdf cat 1-5 7-10 output output.pdf to keep pages 1 through 5 and 7 through 10, effectively deleting pages 6, 8, and 9.

The syntax takes practice. If you find command-line tools confusing, stick with the online tools or Acrobat Pro. PDFtk is powerful and free, but it is slower to learn than clicking buttons.

What to do if the PDF is locked or restricted

Some PDFs have security settings that prevent editing, even in Acrobat Pro. You will see a message like "This document is restricted" or "You do not have permission to edit this file." This usually means the document owner set a password to prevent changes.

If you own the document or have the password, open it in Acrobat Pro, go to File > Properties, and look for a Security tab. Click it and enter the password to unlock editing. Then you can delete pages normally.

If you do not have the password and do not own the document, you cannot legally remove the restriction. Some online tools claim to unlock PDFs, but using them on a document you do not own may violate copyright law. If you need to edit a restricted PDF, contact the person who created it and ask them to remove the restriction or provide an unrestricted copy.

Recovering a page you deleted by mistake

If you deleted a page and saved the file, you cannot undo it within the PDF tool itself. Your best option is to use your computer's file recovery or backup system. On Windows, right-click the file, select Properties, then look for a Previous Versions tab. On Mac, use Time Machine if you have backups turned on.

If you do not have backups, you may be able to recover the file using free recovery software like Recuva (Windows) or EaseUS Data Recovery (Mac and Windows), but success depends on how long ago you deleted it and whether the file has been overwritten. The sooner you try recovery, the better your chances.

To avoid this problem in the future, save a backup copy of important PDFs before you edit them. Use File > Save As and give the edited version a new name, so you always have the original.

Frequently Asked Questions

Can I delete pages from a PDF on my phone or tablet?

Yes, but the process depends on what app you use. Adobe Acrobat Reader for iOS and Android does not have a delete function, but paid apps like PDF informed (iOS) and Xodo (Android) do. Alternatively, upload the PDF to an online tool like ILovePDF using your phone's browser, delete the pages, and read the result.

Will deleting a page change the page numbers of the pages after it?

Yes. If you delete page 5 from a 10-page document, the old page 6 becomes the new page 5, and so on. The total page count drops by one. This is automatic and happens in every tool.

What if I want to delete every page except a few?

In Acrobat Pro, it is faster to select the pages you want to keep rather than clicking every page you want to delete. In online tools, most let you click a Select All button and then uncheck the pages you want to keep. Check the tool's interface for this option before manually clicking each page.

Can I delete pages from a PDF that is password-protected?

Not without the password. If the PDF has a password to open it, you must enter the password first. If it has a password to prevent editing, you must unlock it in Acrobat Pro or contact the document owner to remove the restriction.

Does deleting a page reduce the file size?

Usually yes, but not always by much. A page with mostly text might only reduce the file size by a few kilobytes, while a page with high-resolution images could reduce it by several megabytes. The reduction depends on what is on the page you removed.
