PDF Page Reorder

This tool changes the order of pages inside a PDF. After you choose a file it renders a thumbnail for every page, and you move pages one position at a time with the left and right arrows under each thumbnail. When the order looks right, click Save in new order to download a new PDF with the pages rearranged. Besides reordering, each thumbnail can be duplicated or deleted, and the exported PDF follows your edited list. It cannot rotate pages or merge several files; for those, use the other PDF tools on this site.

How to use it

1. Click the dashed box that says Click to select a PDF file and choose a PDF from your device. The box then shows the file name.
2. Wait until the message Generating page previews… goes away. The more pages there are, the longer it takes.
3. In the thumbnail grid, each page has a left arrow ◀, its current position number and a right arrow ▶ underneath. ◀ moves that page one place earlier and ▶ moves it one place later. The ◀ on the first page and the ▶ on the last page are greyed out.
4. A second row under each thumbnail has two icons: Duplicate page inserts an identical copy right after that page, and Delete page removes it from the list (the last remaining page cannot be deleted). Delete asks for no confirmation, but the original file is untouched; choose the file again to get all pages back.
5. Keep clicking until the order is what you want. The number under a thumbnail is the current position, not the page number in the original file.
6. Click Save in new order. The button reads Saving… and your browser then downloads a file called reordered.pdf.

A real test

The following comes from an actual test with the same PDF library (pdf-lib). We built a three-page test file in which pages 1 and 2 are portrait at 595 by 842 points and page 3 is landscape at 842 by 595. Then we copied the pages in the order 3, 1, 2. The new document had page sizes of 842 by 595, 595 by 842 and 595 by 842 in that order. So the pages did follow the requested order, and each kept its own size; the landscape page was not turned into portrait. If your original is cover, contents, body and you want the contents ahead of the cover, you only need to click ◀ once on the contents thumbnail.

Limits and known quirks

• Only the left and right arrows move pages, one place at a time. There is no mouse dragging, so moving one page a long way in a long document takes many clicks.
• You can reorder, duplicate and delete pages (at least one page must remain), but not rotate them or merge files. A duplicated page is a separate page in the exported PDF with the same content as the original.
• Thumbnails are rendered at a small scale (0.4), enough to recognise a page but not to inspect details.
• Saving copies pages from the original into a fresh document, so document-level features such as bookmarks, form fields and link destinations may not be kept or may no longer point where they did. With a structurally complex PDF, open the result and check it.
• Password-protected files and damaged files cannot be read, and the page shows: Could not read this PDF file. Please make sure it isn't corrupted.
• Everything happens in browser memory, so a PDF with very many pages or a very large size may be slow or fail.

Do page numbers update after I move a page?

No. The tool only changes the order of pages and leaves their content alone. If page numbers are printed on the pages, they travel with the pages, so shuffled pages will show shuffled numbers. If you need to renumber, use the PDF page numbers tool on this site afterwards.

Why do the previews look blurry?

To keep rendering fast, thumbnails are drawn small. They exist only to help you recognise each page. The saved file uses the original pages, so quality is not reduced by this.

Will the saved file be larger or smaller?

It should be close to the original but is not guaranteed to match. The pages are copied into a new document together with the fonts and images they use, and content in the original that no page refers to is not carried over, so the result is sometimes a little smaller. We did not run a size comparison across files, so we make no claim about how much it changes.

Does it work with scanned or image-only PDFs?

Yes. The tool deals only with page order and does not care whether a page contains text or an image. As long as the file opens normally, you can reorder it.

Privacy and processing

The file you choose is processed only inside your browser. The previews are made by a PDF rendering component bundled with the site and the saving is done by the bundled pdf-lib component, and the page contains no code that uploads your file. The new PDF is downloaded straight to your device. Nothing is kept once you refresh or close the page. For sensitive documents, delete the downloaded copy when you have finished.
