Organize PDF

Put the pages of a PDF in the order you want. Drag the page cards to move them, rotate a page 90°, duplicate it, delete it, or drop in a blank page — then download the new PDF. Free, no signup, and the file never leaves your browser.

Page cards, in the order they will be written

No pages yet — choose a PDF file.

Each card shows which page it came from, its size in points and its current rotation. Drag a card onto another card to move it — the card you drop on shows a blue edge on the side the page will land. No preview image is drawn, because the PDF is never rendered.

Insert a blank page

Pick a position, then press Insert blank page. The blank page takes the size of the nearest page — the one before it, or the first page when the blank goes at the start — so it matches the rest of the document.

Pages in the new order

No PDF loaded yet.

The order listed here is exactly the order written to the downloaded file. Pages are listed by their number in the original PDF, and blanks are marked.

What is a PDF organizer?

A PDF organizer changes the order and the arrangement of the pages inside a PDF without touching what is printed on them. It is the digital version of spreading a report out on a table, shuffling the sheets into the order you want, turning one sideways, slipping in a blank sheet, and clipping the stack back together.

Here that table is a grid of page cards. Every card stands for one page and shows which page it came from, its size in points and its current rotation. Drag a card to a new position, or use the Move buttons, and the new order is listed immediately underneath. Each card also carries its own controls: rotate a quarter turn left or right, Copy the page, or Delete it from the output. A separate control inserts a blank page at any position you choose, which is what you want when a section has to start on the right-hand side of a duplex print, or when pages need to be separated.

Two things this tool deliberately does not do. It does not edit the words, pictures or layout on a page — it moves and turns whole pages. And it does not show a picture of each page: the PDF is never rendered to an image, so the cards carry the page number, the page size in points and the rotation instead of a thumbnail. That keeps the tool fast on long documents, keeps memory use low, and means the document is never passed through a renderer.

Everything runs in your browser with the open-source pdf-lib library. The file is read from your own disk, the new document is assembled in memory on your device, and the download is written straight back to you. There is no upload, no account, no server-side copy and no queue — which is what makes it safe for contracts, payslips and medical letters.

How to use this PDF organizer

Press Choose a PDF file and pick the document. The tool reports the file name, the page count and the file size, then builds one card per page, in the original order.
Drag a card and drop it onto another card. The card you drop onto shows a blue edge: on the left it means the page will land before that card, on the right it means after it. The ← Move and Move → buttons on each card do the same job from a keyboard or on a touch screen, where drag-and-drop is unreliable.
Press ↺ 90° or ↻ 90° on a card to turn that page a quarter turn anti-clockwise or clockwise. Press again to turn it another 90°, which is how a page is turned upside down. The rotation reading on the card updates each time.
Press Copy to duplicate a page — the copy is inserted directly after the original — or Delete to leave a page out of the download. The counter under the grid keeps score: how many pages the new document will have, how many original pages were dropped, how many were duplicated and how many blanks were added.
To add a page that is not in the file, choose a position in Insert a blank page and press Insert blank page. The blank card behaves like any other: move it, copy it, or delete it again.
Press Reverse order to flip the whole sequence from end to start, or Reset to original to undo every change and start again from the file you loaded.
Press Download organized PDF. The new document is assembled in the order shown on screen and saved by your browser as your-file-organized.pdf. Your original file is left exactly as it was.

Worked example: four pages reordered to 4, 1, 3, 2 with page 2 turned 90°

The example file is a four-page PDF built for this test. The four pages are deliberately different widths — page 1 is 400 × 700 pt, page 2 is 401 × 700 pt, page 3 is 402 × 700 pt and page 4 is 403 × 700 pt — so the page order of the downloaded file can be read back and checked instead of taken on trust.

Step 1. Load the file. Four cards appear, numbered 1 to 4 in the original order, and the counter reads “4 pages in the new order”.

Step 2. Drag the card for PDF page 4 to the front. The order listing now reads 4, 1, 3, 2.

Step 3. Press ↻ 90° on the card for PDF page 2, which is now the fourth card. Its card shows “rotated 90°”.

Step 4. Press Download organized PDF. The browser saves handbook-organized.pdf, four pages long.

The new document is written in exactly this order:

Position in the new PDF	Card	Page size in the file	Rotation stored on the page	Displays as
1	PDF page 4	403 × 700 pt	0°	403 × 700 pt
2	PDF page 1	400 × 700 pt	0°	400 × 700 pt
3	PDF page 3	402 × 700 pt	0°	402 × 700 pt
4	PDF page 2	401 × 700 pt	90°	700 × 401 pt — turned sideways

Reading the four page widths back from the downloaded file gives 403, 400, 402, 401 — the order that was asked for, with no page lost and none repeated. The last page reports a stored rotation of 90°, and its media box is still 401 × 700 pt: a rotation in a PDF is a note on the page telling the viewer to turn it, not a change to the page itself, which is why the page measures the same but displays on its side.

Rotation is added to whatever the page already carried. If page 2 had already been turned 90° in the source file, pressing ↻ 90° once would store 180° rather than 90°, and pressing it three more times would return the page to 0°. The same applies to pages that arrive sideways from a scanner: the organiser preserves the existing rotation instead of overwriting it.

It is the same run when something is removed or added. Deleting the card for page 3 and then pressing Copy on page 1 turns the order 4, 1, 3, 2 into 4, 1, 1, 2: still four pages, with page 3 gone and page 1 appearing twice — the copy lands directly after the original. The counter reports “4 pages in the new order · 1 original page removed · 1 page duplicated”, so the counts can be checked against the cards before anything is downloaded.

Who is this PDF organizer for?

Office and admin work: scanners feed pages in whatever order the stack was in, and exports from other systems hand back a cover sheet in the middle. Reorder the bundle here, add blank sheets where a section must start on a fresh side, and email one correct file instead of a pile of loose pages.
Students and researchers: put a paper's figures, appendices and reading list in the order you want to read them, and turn the landscape tables and wide diagrams upright so they display properly on a laptop or a phone.
Legal, HR and accounts: move a signature page back to the end of a contract where it belongs, reorder exhibits to match the list in the covering letter, drop the superseded page from a policy document, or duplicate a form page that has to be completed twice.
Anyone handling confidential documents: because nothing is uploaded and no page is ever rendered, payslips, medical letters, client invoices and ID scans can be organized on a work laptop without sending them to a third-party service or leaving a copy behind.

Reordering vs rotating vs splitting: which PDF tool do you need?

Four jobs get confused with each other, and they are four different tools on this site. The intent behind each one is different, so each has its own page:

Tool	What it changes	What you get	Use it when
Organize PDF (this page)	Page order, plus rotation, duplicates, deletions and blank pages	One new PDF	The pages are all there, but the running order — or one page's orientation — is wrong
Rotate PDF	Rotation only; the order is untouched	One new PDF	Pages are sideways but already in the right order, and you want to turn every page at once
Split PDF	Nothing inside a page — it copies ranges out	Several PDFs, one per range or per group of N pages	You want separate documents rather than one corrected document
Extract Pages From PDF	Nothing inside a page — it copies the pages you pick	One new PDF with only the pages you selected	You want one smaller file made of chosen pages, keeping their existing order
Delete Pages From PDF	Drops pages; the order of the rest is untouched	One new PDF	Removing pages is the whole job and the order is already fine

Change the order: organize. If the only problem is that page 7 should be page 2, this is the page to use. It does the whole job in one pass. The long way round — split the file into single pages, then merge them back in the right sequence — needs two tools, makes a folder of intermediate files, and copies every page twice.

Change the direction: rotate. Rotation is per-page and does not move anything. If a scan came out sideways and the order is already correct, Rotate PDF is the shorter route because it can turn every page in one action, and it lets you turn only the pages you name. This page also rotates — the buttons are on each card — but only as part of a page that can also reorder, duplicate and delete.

Change the file count: split. Split PDF answers “I need several files”, not “I need this file fixed”. Splitting a 30-page report into three chapter files and reordering the pages of that report are different requests, and the tool that answers one does not answer the other.

Change what is kept: extract or delete. Extract Pages From PDF writes one new file containing only the pages you name, in the order they already run — the tool for “send them just the appendix”. Delete Pages From PDF is the mirror image: it keeps everything except the pages you remove, with select-all, select-odd and select-even helpers for the job of stripping a scan. Reach for this page instead when the surviving pages also need to move, or when a duplicated or blank page has to be added.

All four tools share the same guarantee: the pages are copied as they are, nothing is re-rendered or re-compressed, and the work happens in your browser.

Common use cases

Fixing a scanner that fed the stack back-first — load the file, press Reverse order, download.
Putting the cover page, the summary or the signature page where it belongs in a long report.
Turning landscape tables, wide charts and rotated scans upright so they read properly on screen.
Inserting blank pages so a printed document starts each section on the front side of a duplex sheet.
Duplicating a form page that has to be filled in more than once, instead of printing it twice.
Dropping a superseded page or an internal note before sending a document to a client.
Reassembling a bundle of invoices or exhibit pages into the order the covering list expects.

Pro tips

Reverse is the fastest fix for a back-to-front scan. Scanners that feed face-down are the most common cause of a document that reads from the last page to the first; one press on Reverse order turns 1, 2, 3, 4 into 4, 3, 2, 1 without dragging a single card.
Read the counter before you download. It states the page count of the new document and how many pages were removed, duplicated or added as blanks. If those numbers do not match what you intended, nothing has been written yet — press Reset to original and start again.
Rotate in 90° steps and watch the card. Each press adds a quarter turn to whatever the page already carried, so 0° becomes 90°, then 180°, then 270°, then back to 0°. A page that displays upside down is 180° out, so two presses turn it back.
Use blanks for double-sided printing. A page that must start on a fresh sheet needs an even number of pages in front of it: insert a blank after the pages before it, and the section begins where you want it on paper.
Use Reset rather than reloading the file. Reset to original restores every page, clears rotations, duplicates and blanks, and does not re-read the file — so a wrong experiment costs one click, not another file dialog.
Your original is safe. Nothing is written to the file you loaded; the download is a new document named after it with -organized added, so the source PDF is still there untouched.

FAQ

Are my PDF files uploaded to a server?

No. The organiser runs entirely in your browser with the pdf-lib library, so the file is read from your own disk and the new document is assembled on your device. Nothing is uploaded, nothing is sent to a third party, and no copy of the document is stored.

Does reordering pages reduce the quality of the PDF?

No. pdf-lib copies the original pages exactly as they are, so text stays selectable vector text, images keep their original resolution, and nothing is re-rendered or re-compressed. Only the order of the pages, and any rotation you asked for, changes in the new file.

How do I move a page in a PDF?

Drag the page card to the position you want and drop it: the card you drop onto shows a blue edge on the left to mean before that page, or on the right to mean after it. The Move buttons on each card do the same job with a keyboard or a touch screen, and the counter updates straight away.

Does rotating a page here rotate it in my original file?

No. The file on your disk is never modified. Rotation is written into the new document only, as a rotation entry on the page. If a page already carried a rotation, the 90° you press is added to it, so pressing rotate once on a page that was already at 90° stores 180°.

Can I duplicate a PDF page?

Yes. Press Copy on a card and an exact copy of that page is inserted straight after it. You can press Copy as many times as you need, so one page can appear several times in the new document — useful for a page that has to be signed or filed more than once.

Can I insert a blank page in the middle of a PDF?

Yes. Choose a position in the Insert a blank page list and press the button. The blank page takes the size of the nearest page — the page before it, or the first page of the document when the blank goes at the very start — so it matches the rest of the file. Blank pages appear as cards like any other page and can be moved, copied or deleted again.

Can I delete pages here instead of using the Delete Pages tool?

Yes, press Delete on any card and that page is left out of the download. If removing pages is the whole job and the running order is fine, the Delete Pages From PDF page is quicker, because it offers select all, select odd and select even in one click. Use this page when the order changes as well.

Can it sort PDF pages automatically, for example alphabetically?

No. This organiser never reads the text on a page, so it cannot sort by title, date or content. Ordering is manual: drag the cards, use the Move buttons, or press Reverse order to turn 1, 2, 3, 4 into 4, 3, 2, 1. Reset to original puts every page back in the order it was loaded in.

Can I combine two PDFs with this tool?

No — this page works on one file at a time. To put two documents together, merge them first with the Merge PDF tool and then organize the merged file here. Organizing is usually the second step: combine, then fix the order.

Why do the cards show page sizes instead of a preview image?

Because the PDF is never rendered. Drawing each page would mean rasterising it to a canvas, which is slower on long documents and uses much more memory. The cards carry the page number, the page size in points and the current rotation instead, which is everything the organiser needs to write the new file.

Is there a limit on the number of pages?

There is no fixed limit. Because nothing is rendered, the cards are light and a document of several hundred pages is handled comfortably — the real constraint is your device's memory, since the file and the new document are both held in the browser while you work.

Is this PDF organiser free, and does it add a watermark?

Yes, it is free. There is no sign-up, no email gate, no page limit, no daily counter and no watermark. The download is your own document with the pages in the new order, saved by your browser like any other file.
