What Reorder PDF Pages does
Load a PDF and the tool renders a thumbnail of every page. Drag the thumbnails into the order you want and save; the result is a new PDF with the pages in that sequence and nothing else changed. Pages are copied as objects rather than re-rendered, so text stays selectable, images keep their resolution and the file size barely moves. Rendering and rebuilding both happen in your browser — the document is never uploaded.
When pages end up in the wrong order
- Scanner mishaps — a stack fed face-down comes out reversed; a duplex scan can interleave fronts and backs incorrectly.
- Merged files — combining PDFs in the wrong sequence, or an appendix that belongs before the references.
- Booklet or imposed prints — pages saved in printing order rather than reading order.
- Assembled reports — moving an executive summary to the front, or a cover page that was exported last.
- Exported slides — a deck reorganised after export.
How to use it efficiently
| Task | Approach |
|---|---|
| Reverse a whole document | Drag the last page to the front, then the new last page, and so on — or split to single pages and merge in reverse |
| Move one page | Drag it directly to its new spot; the others shift automatically |
| Swap two pages | Drag the first onto the second's position, then the second into the gap |
| Large documents | Thumbnails are small; zoom the browser (Ctrl/Cmd +) to read page numbers on them |
Thumbnails are rendered at reduced resolution for speed; a 200-page document takes a few seconds on a laptop. The page index shown on each thumbnail is its original position, which helps when checking your work against the source.
What is preserved
- Page content, fonts, images, vector graphics — identical bytes.
- Page size, orientation and rotation of each page.
- Annotations and form fields attached to pages.
- Not preserved: bookmarks (the outline), which reference pages by position and are dropped; document metadata such as title and author; and internal link targets, which may now point to the wrong page.
Reorder vs the other page tools
Reorder keeps every page and changes the sequence. To drop pages, use Delete Pages; to keep only some, use Extract Pages; to combine documents, use Merge. A common workflow for a messy scan is: delete blanks, reorder, then add page numbers — in that order, so the numbers reflect the final sequence.
