How to Delete Pages from a PDF (Without Re-Splitting and Merging)

You have a 40-page report and you want pages 12, 27, and the last three gone. The clumsy old way: split the PDF into 40 individual files, drag the ones you want into a merge tool, and rebuild. The fast way: a dedicated delete pages tool that takes a comma-separated list and writes a single new PDF.

This guide covers three free ways to remove pages from a PDF, with the syntax tricks that save the most time.

The Page-Range Syntax Most Tools Accept

Almost every modern PDF editor uses the same shorthand for page selection:

• 3 — page 3 only
• 1,5,8 — pages 1, 5, and 8
• 2-7 — pages 2 through 7 (inclusive)
• 1, 4-6, 10 — page 1, pages 4–6, and page 10

If you ever wonder why your tool rejected something — usually it's an extra space in the wrong place, or you used a hyphen the document treats as a date separator. Stick to comma-separated, dash-for-ranges.

Method 1: AllPDF.tools Delete Pages (Free, In-Browser)

1. Open AllPDF.tools Delete Pages.
2. Drop your PDF — the page count appears.
3. Type the pages you want gone (e.g. 2, 4-6, 10).
4. Click Remove Selected Pages and download.

Refuses to delete every page (you'd be left with nothing). Tells you which page numbers it ignored if you typed something invalid. Runs entirely in your browser.

Method 2: Adobe Acrobat Pro

If you have Acrobat Pro:

1. Open the PDF.
2. Tools → Organize Pages.
3. Select pages to remove (Ctrl/Cmd+click for multiple).
4. Click the trash icon, save.

Acrobat's visual page strip is great for browsing-and-deleting when you don't know the exact page numbers. But for a known list of pages, typing into a text field is faster.

Method 3: macOS Preview / Linux PDF Tools

macOS Preview (free, built-in): View → Thumbnails → select pages → Delete key → save. Works for small jobs.

Linux: pdftk input.pdf cat 1-11 13-26 28-end output result.pdf — note this is "keep these ranges" not "delete these", which is the inverse mental model.

Common Questions

Will deleting pages reduce the file size?

Yes, proportionally. Deleting half the pages typically halves the file size, give or take. If you also want to compress what remains, run the result through Compress PDF.

Can I undo a page deletion?

The output is a new file — your original is untouched. If you saved over the original by mistake, restore from your trash, version history, or cloud backup.

What about page numbers — do they auto-update?

If your PDF has page numbers baked into the content (most do), they will NOT renumber. Page 1 might still say "Page 1" but page 2 might say "Page 3" because the original page 2 was deleted. Run Add Page Numbers to get a clean fresh sequence.

Can I delete pages from a password-protected PDF?

You need to remove the password first. Most page-delete tools refuse to operate on encrypted files for security reasons.

Will the bookmarks / table of contents still work?

Bookmarks pointing to deleted pages will become dead links. Bookmarks pointing to surviving pages should still resolve, though some viewers will show a one-time warning. For a clean TOC, regenerate it after deletion.
