It happens more often than you'd think: you scan a stack of paper and the scanner reads it from the bottom, so page 1 ends up last. Or you print a document and the printer delivers the sheets face-up in reverse. Reverse PDF flips the order of every page with one click, so the last page becomes the first and the first becomes the last, without any dragging or typing page numbers.
How to reverse a PDF
- Open your PDF. Thumbnails of the pages appear in their new, reversed order.
- If the first page is a cover that should stay at the front, tick Keep the first page in place.
- Check the order in the preview and the list of page numbers.
- Click Save reversed PDF.
The thumbnails and the page list show the new order before you save, so you can be sure it's right.
Why a PDF ends up in reverse
Several common situations produce a backwards document. Some scanners with an automatic document feeder pick up the last sheet first. A scanning app might append each new scan at the beginning instead of the end. Copiers set to "reverse order" for stacking can leave you with files that were meant for a different purpose. And if you scan both sides of a stack, the second pass often gives you the back pages in descending order. For that last case, you may not need to reverse the whole file; Alternate & Mix PDF can interleave fronts and backs and reverse one of them in a single step.
Keeping the cover in place
Documents often begin with a cover or title page that shouldn't move. The "Keep the first page in place" option reverses everything except that first page, so a 5-page document becomes 1, 5, 4, 3, 2 instead of 5, 4, 3, 2, 1. It's a small thing, but without it you'd have to reverse the document and then move the cover back by hand.
Rotation is preserved
Pages that were stored sideways keep their rotation; only their position changes. A landscape table on page 3 is still a landscape table on its new page. The text stays selectable, nothing is re-compressed, and the file size stays almost exactly the same, because pages are moved rather than re-made.
Related page-order jobs
- Move a few pages instead of all of them: Organize PDF lets you drag pages around visually.
- Remove pages that shouldn't be there at all with Delete PDF Pages.
- Pull out a section and reverse only that part: use Split PDF to extract it first.
- Number the final order with Add Page Numbers, which is best done after the order is settled.
- Combine reversed parts into one document with Merge PDF.
A worked example
You've scanned a 14-page rental pack on a feeder that read it from the back. Open the file here and the first thumbnail is now what used to be page 14. If the cover letter was page 1, it had been last; with the cover option off, it returns to the front. Save the file and read through quickly: you'll notice page numbers printed on the paper now run correctly from 1 to 14. If you're not sure which way is right, open the original in your PDF reader and look at the printed page numbers.
Printing in reverse
Reversing isn't only for fixing mistakes. Some printers output pages face-up, so the last page ends up on top of the pile. If you print a long document and have to re-sort it, print a reversed copy instead. The same applies to old inkjets and some office copiers. And if you're saving paper, you can combine this with Multiple Pages per Sheet to print a compact copy in the order your printer needs.
The page order is changed in your browser and the file is never uploaded. Protected PDFs need to be unlocked in your reader first, and the original on your computer is never changed.
Troubleshooting
If the result is not what you expected, check whether the original was actually in the wrong order: some documents start with a cover and end with an appendix, which looks reversed but isn't. Use the printed page numbers as your guide. If only part of the document is backwards, split it first with Split PDF, reverse that part and merge the pieces again. If nothing seems to happen, make sure you've opened a PDF with more than one page, since a single page has no order to reverse.
Why not just drag the pages?
You can, with Organize PDF, but with a 60-page document it's tedious and easy to get wrong. Reversing is a single, exact operation, with no dragging and no mistakes. Use the drag-and-drop tool when you need a custom order, and this one when the whole sequence is simply back to front.
