Reorder and Organize PDF Pages
Drag and drop to reorder the pages of your documents with a smooth and 100% private interface.

Reorder, rotate and delete PDF pages on one screen
Drag pages into the order you want, turn the sideways ones upright and drop the ones you do not need — then export a single reassembled document.
Most page problems arrive together. A scanned batch comes back with the pages in feeder order rather than reading order, three sheets went through upside down, and there is a blank separator between every document. Fixing that with separate extract, rotate and merge steps means exporting an intermediate file at each stage and losing track of where you are.
This tool puts the whole document on one screen as a grid of page thumbnails. You drag to reorder, click to rotate, and mark for deletion — and nothing is committed until you export. Until then you are editing a plan, not the file.
Everything runs in your browser, including rendering the thumbnails. A document you are still sorting out is usually one you are not ready to hand to anyone, which is exactly when uploading it to a web service is least appealing.
Nothing is uploaded
Thumbnails are rendered and the document is rebuilt inside the tab. The file never reaches a server.
Three operations, one pass
Reorder, rotate and delete are applied together when you export, instead of round-tripping the file through three separate tools.
Nothing changes until you export
The grid is a plan. Rearrange as much as you like and the source file stays untouched until you download the result.
How to organize PDF pages
Open the PDF and let the page thumbnails render.
Drag pages into the order you want.
Rotate the sideways ones and mark any to delete.
Export the reassembled document.
The document never leaves your device
Even the thumbnails are rendered locally. A document you are still reorganising is rarely one you want on someone else's server, and here it never gets there.
When people reach for this
Sorting out a document feeder's output
A duplex scanner that reads all the fronts and then all the backs leaves you with pages 1, 3, 5 followed by 2, 4, 6. Interleaving them by hand on a grid takes a minute; doing it with extract-and-merge takes considerably longer.
Fixing pages that scanned sideways or upside down
A landscape table in a portrait report, or a sheet that went in the wrong way round. Rotating just those pages is far quicker than rescanning the batch.
Removing blanks and separators
Duplex scanning a single-sided stack produces a blank between every page. Deleting them in one pass halves the document.
Rearranging a deck or a report before circulating it
The appendix should come after the conclusions, the cover page belongs at the front, and the draft note in the middle should go. All three are the same operation here.
What actually happens to your file
The grid you interact with is rendered by pdf.js: each page is drawn to a small canvas so you can see what you are moving. That preview layer is display only — dragging a thumbnail does not touch the document.
When you export, the arrangement is serialised into a page map describing which source page goes where, and with what rotation, and handed to pdfcpu compiled to WebAssembly.
The engine then works in three stages. It trims each requested page out of the source into its own single-page document. It merges those single-page documents in the order your map specifies, renumbering the object graphs so they combine cleanly. Finally it applies the rotations you asked for to the pages that need them.
Deleted pages are handled by omission: they are simply never trimmed out, so they do not appear in the merge. Nothing has to erase them, because they are never carried across.
Because every stage moves pages rather than redrawing them, the result is lossless — the pages in your reassembled document are the pages you started with.
Where it falls short, honestly
- Rendering thumbnails for a long document takes time and memory. A 500-page scan will be slow to open, because every page has to be drawn before you can see the grid.
- Bookmarks and internal links generally do not survive. Their targets are renumbered and reordered during the rebuild, so links that pointed to page 40 will not follow it to its new position.
- Form fields may stop working after a reorder, for the same reason.
- It cannot tell you which pages are blank. Separators have to be spotted by eye on the grid; nothing analyses the page content to flag them.
- Encrypted files must be unlocked first — pages cannot be read, rendered or moved while the document is encrypted.
- Because pages are extracted and remerged, the output is not always smaller than the input even when you delete pages, since shared resources may be carried across.
Compared with an online page organiser
| This tool | Typical cloud tool | |
|---|---|---|
| Where your file goes | Nowhere. It stays in the browser tab. | Uploaded before you can even see the pages. |
| Reorder, rotate and delete together | Yes, in a single export. | Often three separate tools and three round trips. |
| Quality | Lossless — pages are moved, not redrawn. | Usually lossless, but unverifiable. |
| Page limits | Bounded only by your device's memory. | Commonly capped on free tiers. |
| Works offline | Yes, once the page has loaded. | No. |
| Watermarks | None. | Frequently added on free tiers. |
