How to Reorder, Duplicate or Drop Pages in a PDF
Rearrange PDF pages by typing the order you want, like "3, 1, 2, 4-10". Move an appendix to the front, repeat a cover page or remove pages in one step.

Sometimes the pages are all there, just in the wrong order. A scan where the pile got shuffled, an appendix that should be at the front, or a merged PDF where one document landed in the wrong spot.
Organize PDF lets you type the order you want and get a new PDF back.
How the page order works
You type a list of page numbers. The new PDF follows that list exactly:
3, 1, 2→ page 3, then 1, then 2.1, 5-10, 2-4→ page 1, then 5 to 10, then 2 to 4.10-1isn't needed. Just list them:10, 9, 8, …1, 2, 1→ page 1 appears twice.- Anything you don't list is dropped.
That last point makes it a reorder-and-trim tool in one.

Tips
- Check page numbers in your PDF reader first. Use the physical page number (1, 2, 3…), not any number printed on the page.
- Reversing a whole document (scanner fed the pile backwards) is just the numbers listed from last to first.
- Only want to remove pages? Remove PDF Pages is simpler.
- Only want a few pages? Extract PDF Pages creates a new PDF with just those.
Other ways
Mac Preview lets you drag thumbnails around in the sidebar, which is nice and visual for short documents. On Windows, there's no built-in way. Acrobat Pro has an "Organize Pages" view.
Order examples
| You type | Result |
|---|---|
3, 1, 2, 4-10 | Page 3 moves to the front |
10-1 | Pages 10 down to 1 (reversed) |
5- | Page 5 to the last page |
1, 5-10 | Pages 2–4 are removed |
1, 1, 2-6 | Cover page appears twice |
Any page you leave out is removed, so double-check the list before converting.
Tips
- Check page numbers in the PDF viewer first.
- Reversing a scan stack? Type a backwards range, e.g.
6-1.
Summary
Type the order, get the PDF. Organize PDF Pages reorders, repeats and trims in one step, with no loss of quality.
FAQs
How do I write the page order?
List page numbers separated by commas, with ranges using a hyphen. "3, 1, 2, 4-10" puts page 3 first, then 1 and 2, then 4 to 10.
What happens to pages I leave out?
They're removed from the new PDF. That makes it handy for reordering and trimming at once.
Can I repeat a page?
Yes. List it more than once, for example "1, 2, 1, 3".
Does it change quality?
No. Pages are copied exactly as they are.
