Answer: Drag and drop PDF thumbnails into any order to reorder pages, then export the rearranged document.
Drag thumbnails into any order — the download is rebuilt that way
| Approach | Effort | What you get |
|---|---|---|
| Drag thumbnails (this tool) | Seconds | Rebuilt PDF in your exact order; pages copied untouched; delete and rotate while you're there |
| Re-scan or re-export the source | Minutes to hours | Right order, but you redo work and risk quality loss on every pass |
| Print to PDF page-by-page | Tedious | Loses links and selectable text; page order is the only thing you fix |
| Full desktop editor | Install + learn | Works, at the cost of software (and often a subscription) for a job that's one drag |
Page order lives in the PDF's page tree — an ordered list the viewer walks to display the document. Rearranging means rebuilding that list, which is exactly what this tool's export does: pdf.js renders each page as a thumbnail you can drag, and pdf-lib copies the pages into a fresh file in your chosen sequence. Nothing about the pages themselves changes.
An 8-page contract goes out with the signature page last, but legal wants it right after the cover. Open the file, drag the page-8 thumbnail onto the page-2 card, and the grid reads 1, 8, 2, 3, 4, 5, 6, 7. Download and the output is those 8 pages in that order — the signature page is now output page 2, cover still first, nothing re-rendered. The classic duplex-scan case works the same way: a 20-page two-sided original that scanned odds-then-evens needs a dozen drags (or arrow presses) to become reading order.
The most common reason people need this tool is a two-sided document fed through a one-sided scanner. You scan the fronts, flip the stack, scan the backs, and the backs come out in reverse. For a 10-page original, the scanned file holds pages 1, 3, 5, 7, 9, then 10, 8, 6, 4, 2.
The fix follows a pattern: take the first file page, then the last, then the second, then the second-to-last, and keep alternating inward. Here's the order to drag the thumbnails into, using the numbers the tool shows on each card:
| Pages in original | How the scan comes out | Drag thumbnails into this order |
|---|---|---|
| 4 | 1, 3, 4, 2 | 1, 4, 2, 3 |
| 6 | 1, 3, 5, 6, 4, 2 | 1, 6, 2, 5, 3, 4 |
| 8 | 1, 3, 5, 7, 8, 6, 4, 2 | 1, 8, 2, 7, 3, 6, 4, 5 |
| 10 | 1, 3, 5, 7, 9, 10, 8, 6, 4, 2 | 1, 10, 2, 9, 3, 8, 4, 7, 5, 6 |
If your scanner outputs the backs in forward order instead, it's a simple interleave: 1, 6, 2, 7, 3, 8 and so on for a 10-page file. Check the first two pages of the output before you send it anywhere. If page 2 is wrong, you've got the other pattern.
A blank back page is still a page in the scan. Delete it with × after reordering, not before, or the pattern above shifts by one.
The tool doesn't edit your PDF in place. It creates a new, empty PDF and copies each page into it in the order you set. Anything that lives on a page travels with it. Anything that belongs to the document as a whole stays behind.
| Part of the PDF | In the reordered copy? |
|---|---|
| Text, images, fonts, vector graphics | Yes, unchanged. Text stays selectable and nothing is re-rendered |
| Page size and rotation | Yes, plus any quarter-turns you apply with ⟳ |
| Comments, highlights, stamps | Yes, on the pages they were attached to |
| Web links | Yes |
| Links that jump to another page | Can break, since the target page may have moved |
| Fillable form fields | Can stop being fillable. Test the form before sending it |
| Bookmarks (outline panel) | No |
| Title, author and other document properties | No. The copy gets fresh properties |
For most jobs, like scans, contracts and handouts, none of the "no" rows matter. If you're reordering a long report with a table of contents built from bookmarks, plan to rebuild the outline afterward.
This tool is for order, with rotate and delete as extras. If you mainly want pages gone, Delete Pages from PDF is faster. To pull a few pages out into their own file, use Extract PDF Pages. And to combine several files before sorting their pages, start with Merge PDF, then bring the merged file back here.
Open the PDF in a thumbnail organizer and drag each page card to its new position — or nudge pages with the left/right arrow buttons, which is easier on touch screens. The download is rebuilt with the pages copied in exactly the order shown, so what you see in the grid is what you get in the file.
No. The exporter copies each page's content stream untouched into a new document — text stays selectable, images stay sharp — and only the sequence changes. Rotation applied here is written as the page's rotation value, not a re-render.
Duplex scans often do this: single-sided originals fed through a feeder come out reversed, or odd/even passes stack in opposite directions. A thumbnail reorder fixes it in seconds — drag (or arrow) the pages into reading order and download.
Bookmarks don't carry over at all. The download is a brand-new PDF built from copies of your pages, and bookmarks belong to the original document rather than to any page. If readers rely on the outline, re-add it in a desktop editor after reordering.
Usually not. An encrypted PDF has to be unlocked before its pages can be copied into a new file, so the export fails. Open it with the password in your PDF reader, save or print an unprotected copy, and reorder that instead.
No. Thumbnails are rendered and the new file is built in your browser with JavaScript, so the document never leaves your device. That makes it safe for contracts, medical forms and anything else you wouldn't want on someone else's server.
