Organize PDF
Did a PDF assembled from several scans end up with its pages in the wrong order? This tool shows a thumbnail of each page and lets you move them with the up/down arrows until the order is right, before downloading the reordered document. The processing — thumbnails via pdf.js, final assembly via pdf-lib — happens entirely in your browser.
How it works
- Select a PDF file from your device; the tool generates a thumbnail of each page in its original position.
- Thumbnails appear in the document's original order.
- Use the up and down arrows on each thumbnail to move it to the position you want in the final result.
- Click 'Download reordered PDF' so pdf-lib copies all pages in the new order into a new document (no page is removed, only reordered).
- Download the result as reordered-document.pdf.
Use cases
- Fix the page order of a scan that was digitized out of sequence.
- Move the table of contents or cover page to the start of a report assembled from multiple sources.
- Reorganize a contract's attachments to match the order they're referenced in the body of the document.
- Move the most relevant pages of a long PDF to the front before sharing it.

Common mistakes
- Looking for an option to delete pages while reordering.This mode only reorders; it keeps every page from the original. To remove pages, use the delete or extract pages tools.
- Moving pages one at a time by clicking repeatedly instead of planning the final order before starting.Each arrow click moves a page only one position; to reorder several pages it helps to decide the final order before making the moves, since there's no drag and drop.
- Closing the tab or reselecting the file thinking the order was saved automatically.The new order only applies once you click 'Download reordered PDF'; if you reload the same file, the order resets to the original.
Frequently asked questions
No, all pages are kept; the result has the same number of pages as the original, only the order changes.
No, reordering is done with the up/down arrow buttons on each thumbnail, moving one position per click.
No. Thumbnails are generated with pdf.js and the final document is assembled with pdf-lib, all in your browser.
They're kept exactly as they were in the original; this tool only changes page position, not content or orientation.
Alternatives
Adobe Acrobat lets you reorder pages by dragging them in its thumbnail panel, and macOS's Preview app offers something similar. The advantage of doing it here is not depending on an installed app or a specific operating system: the reordering is computed entirely in the browser.
