The fastest way depends on what you have installed

You can delete pages from a PDF using free software on your computer, a web browser, or a paid desktop program — the choice depends on whether you want to keep the file local, how many PDFs you edit regularly, and what operating system you use. Most people delete pages using either Adobe Acrobat Reader (the free version has limits), Preview on Mac, or a free online tool like iLovePDF or Smallpdf.

The web-based tools are fastest for a single file because you upload, delete, and download without installing anything. Desktop software is better if you delete pages from PDFs regularly, because you keep everything on your computer and do not upload to a server.

Key Takeaways

  • Mac users can delete pages directly in Preview without any other software — select the page in the sidebar and press Delete.
  • Windows users without paid software should use a free web tool like iLovePDF, Smallpdf, or PDF.io, which take about two minutes per file.
  • Adobe Acrobat Reader (free) lets you delete one page at a time but does not let you delete multiple pages in one action.
  • Paid desktop programs like Adobe Acrobat Pro or PDFtk let you delete pages in batches and work faster if you edit PDFs regularly.

Deleting pages on Mac using Preview

If you use a Mac, Preview is built in and handles page deletion without any other software. Open the PDF in Preview, click the sidebar icon (it looks like two rectangles) at the top left, then right-click the page you want to remove and select Delete. You can select multiple pages by holding Shift and clicking, then delete them all at once.

When you are done, press Command+S to save. Preview saves over the original file by default, so if you want to keep the original, use File > Export As instead and give it a new name.

Deleting pages on Windows using free web tools

Windows does not include a built-in PDF editor, so the easiest route is a free web tool. iLovePDF, Smallpdf, and PDF.io all work the same way: upload your file, click the pages you want to delete (they turn red), then download the result. None of them require an account for basic use.

Open the tool in your browser, click the upload button, select your PDF from your computer, wait for it to load (usually 10 to 30 seconds), then click each page you want to remove. The pages you select will be highlighted. Click the delete or remove button, then download the edited file. The whole process takes about two minutes.

These tools delete your file from their servers after a few hours, but if you handle sensitive documents, check the privacy policy first — some tools keep files longer than others, and some let you delete files manually after download.

Using Adobe Acrobat Reader (free version)

The free Adobe Acrobat Reader lets you delete pages, but only one at a time and only if you have a free Adobe account. Open the PDF, click the three-dot menu at the top right, select Organize Pages, then click the trash icon on the page you want to remove. You must save the file after each deletion.

This method is slower than Preview on Mac or web tools on Windows because you cannot select multiple pages at once. If you only delete pages occasionally, a web tool is usually faster. If you delete pages from PDFs regularly, the paid version of Acrobat or a desktop alternative is worth considering.

Using paid desktop software

Adobe Acrobat Pro (the paid version, around $180 per year) lets you select multiple pages and delete them in one action, and it works offline. Open the PDF, click Organize Pages on the left sidebar, select the pages you want to delete by clicking them (hold Shift to select a range), then press Delete.

Other paid options include PDFtk (one-time purchase, around $30 for Windows) and Nitro PDF (subscription, around $120 per year). These programs are worth the cost only if you edit PDFs several times a week — for occasional use, a web tool or Preview is faster and free.

Deleting pages from a PDF on your phone

On iPhone or iPad, use the free Preview app (built in) or Adobe Acrobat Reader (free download). In Preview, open the PDF, tap the page thumbnail at the bottom, swipe left on the page you want to delete, then tap Delete. In Adobe Acrobat Reader, tap the three-dot menu, select Organize Pages, then swipe left on the page and tap Delete.

On Android, Adobe Acrobat Reader is the most reliable option. Open the PDF, tap the three-dot menu, select Organize Pages, then tap the trash icon on the page you want to remove. Some Android phones also have a built-in PDF viewer — check your Files app to see if it can edit PDFs.

What to do if the PDF is password-protected

If the PDF has a password, you must enter it before you can delete pages. Most tools will ask for the password when you upload or open the file. If the password is set to prevent editing (not just viewing), you cannot delete pages without removing the password first.

To remove a password, use a free online tool like iLovePDF or Smallpdf — both have a "Unlock PDF" option. Upload the file, and if it is password-protected for editing, the tool will remove the protection. Then download the unlocked file and delete pages using any method above. If the password is set to prevent viewing, you will need the password itself to unlock it.

Frequently Asked Questions

Can I undo a page deletion after I save the file?

No — once you save, the deletion is permanent. Before you save, you can undo using Ctrl+Z (Windows) or Command+Z (Mac). After you save, the pages are gone. If you are unsure, save the edited file with a new name so you keep the original.

What if I want to delete pages 2, 5, and 8 but keep the rest?

In Preview on Mac, hold Shift and click each page you want to delete, then press Delete once. In web tools like iLovePDF, click each page (they turn red), then click Delete. In Adobe Acrobat Reader free version, you must delete one page at a time. In paid software like Acrobat Pro, select multiple pages by holding Ctrl (Windows) or Command (Mac) and clicking each one, then delete them all at once.

Will deleting pages reduce the file size?

Yes, usually by a small amount. The exact reduction depends on what is on each page — a page with images will reduce the file size more than a page with only text. If you need to shrink a PDF significantly, deleting pages helps, but compressing images or removing embedded fonts works better.

Can I delete pages from a scanned PDF?

Yes — the method is the same whether the PDF is text-based or scanned. Scanned PDFs are just images of pages, so deleting a scanned page works exactly like deleting any other page. The file size reduction may be larger because scanned pages usually contain more image data.
