Organise a PDF

See your pages as thumbnails, move them into the right order with a tap and drop the ones you don’t need — in your browser, so the document never leaves your device.

Runs on your device. Your file is never uploaded.

How to reorder and delete pages in a PDF

1
Choose the PDF
Tap the picker and choose a PDF from your phone, tablet or computer. It is read straight into the page, so there is no upload and no progress bar to wait on. The page count appears as soon as the file has been read, and — for documents up to 100 pages — a thumbnail of each page fills in behind it over the next few seconds.
2
Move pages into the right order
Each page card has a left and a right arrow. Left moves that page one place earlier in the document, right moves it one place later. The cards are big enough to hit with a thumb, so a scanned bundle that came out back-to-front can be fixed on a phone without a mouse.
3
Mark the pages you don't want
Press Remove on any page and it dims with a 'Will be removed' label. Nothing has happened to your file yet — press Keep on the same card to bring it back. Blank separator sheets from a scanner, a duplicated cover page or an internal notes page all come out this way.
4
Save the new PDF
The button at the bottom names exactly how many pages you are keeping. Press it and a new document is built in your browser from the pages you kept, in the order you set — report.pdf becomes report-organised.pdf, which you then download. The original file on your device is never modified.
5
Send it on, if you need to
Most people reorganise a PDF because it is about to be sent to somebody. If that is you, turn the finished file into a shareable link with a QR code instead of attaching it, so the person opening it does not have to download anything first.

Your file never leaves your device

Most online page organisers upload your document to a server, build the thumbnails there, and hand back a download link. For a signed contract, a payslip or a set of medical scans that is a real difference: your file sat on somebody else’s machine, and you are trusting a retention policy you cannot check.

This tool works the other way round. The page loads a PDF library into your browser, and the file you pick is read into that tab’s memory, drawn there, and rewritten there. No request carries your document, nothing is written to storage, and closing the tab is all the cleanup there is. The practical test: choose your PDF, go offline, and finish organising it anyway — the new file is still built and saved, which would be impossible if a server were doing the work. (Go offline before choosing the file and you get numbered cards instead of thumbnails: the preview renderer is fetched when you pick, not when the page loads.)

The only thing that leaves the tab is an anonymous analytics event recording that this tool was used and whether it worked — never the file, its name, its page previews or its contents.

What this tool can’t do

Running on your device buys privacy and speed, and it costs a few things. Worth knowing before you start:

40 MB per file. A parsed PDF takes several times its size in memory, page previews cost more again, and a phone browser kills the tab silently when it runs out. The cap exists so you get a clear message instead of a dead page.
Previews stop at 100 pages. Past that the grid shows numbered cards instead of pictures. Everything still reorders and deletes correctly — you are working by page number rather than by eye.
Pages move one place at a time. There is no dragging page 40 to the front in one gesture, because drag-and-drop inside a scrolling grid is unreliable on a touchscreen. For a big move across a long document, splitting and merging is usually faster than tapping.
Password-protected PDFs are refused. Unlock the document in your PDF reader, save an unlocked copy, and organise that.
It moves pages, it doesn’t edit them. Nothing here changes what is printed on a page — no editing text, no rotating, no merging in a second document. Those are separate tools, linked below.
A very old browser will struggle. The rendering happens on your processor, so a 39 MB document on a five-year-old phone takes a while to draw. On a desktop the previews usually appear in a second or two.

Organise PDF questions

Is my PDF uploaded anywhere when I reorganise it?

No. The page thumbnails and the new document are both produced in your browser, using your device's own processor and memory, so the file's bytes never travel to a server. Nothing is stored, nothing is queued, and there is no copy of your document to delete afterwards. You can prove it: choose your PDF, switch the device to airplane mode, and finish the job anyway — the reordering and the saved file still work offline, which would be impossible if a server were doing them. The one honest caveat is the previews: the renderer that draws them is fetched only when you pick a file, so going offline before that leaves you with numbered cards instead of pictures.

Can I reorder pages without a mouse, on a phone?

Yes — the arrow buttons are the only way pages move here, on purpose. There is no drag-and-drop at all: dragging a thumbnail inside a page that also scrolls fights the scroll and is unreliable on a touchscreen, so every page moves one place at a time with a left or right button big enough for a thumb. The same buttons work with a keyboard and are labelled for screen readers, so 'move page 4 earlier' is a normal button press.

Does deleting a page here make the file smaller?

Usually a little, but less than you would expect. A new document is built from the pages you kept, so anything used only by a deleted page goes with it — but fonts and images shared across the document are carried over to keep the remaining pages correct. Deleting 3 pages from a 30-page report might save a tenth of the size, not a tenth per page. If the file size is the real problem, compressing it is a different job.

Why is there a 40 MB limit?

Because the work happens on your device rather than on a server. A PDF takes several times its file size in memory once it is parsed, and rendering page previews on top of that costs more again, so a 40 MB document can already mean a few hundred megabytes of memory on a mid-range phone — beyond that the browser tab is killed with no message at all. The cap means you get an honest error instead of a frozen tab.

Why do previews stop after 100 pages?

Drawing a preview means rendering that page the way a PDF reader would, which is the most expensive thing this tool does. Above 100 pages the previews are switched off deliberately, because rendering hundreds of them is the fastest way to crash a phone browser. Reordering and removing still work exactly the same on a long document — the cards show page numbers instead of pictures.

Does reorganising change how the pages look, or lose quality?

No. Pages are copied from one document into another exactly as they are, not re-rendered or re-compressed. Text stays selectable and searchable, fonts stay embedded, images keep their original resolution and vector graphics stay vector. A page prints identically after the reorder. Page rotation is preserved too, so a sideways scan stays sideways — use the Rotate PDF tool if that is what needs fixing.

Can I reorganise a password-protected PDF?

Not directly. An encrypted PDF is refused rather than half-processed, because a tool that opens one and then writes a document that will not open later is worse than one that says no. Open it in your usual PDF reader with the password, save an unlocked copy, and reorganise that copy instead.

Once the pages are in order

A tidied-up document usually has somewhere to go. If it is still too big to attach, how to send a large PDF that’s too big for email walks through the options — including why zipping it barely helps. And if you ended up with several documents rather than one, sharing multiple PDFs as one link beats sending a pile of attachments or a folder behind a permission wall.
