Rearrange PDF pages into any order you like

The quick answer

1. Open Organize PDF and choose your PDF. Every page appears as a card, in the order it will be saved.
2. Drag the cards into the order you want: with a mouse from anywhere on the card, with a finger by the dark numbered handle in its top-left corner.
3. Press the yellow Save PDF button, then Download. The new file is named after the old one with -organized added, like report-organized.pdf.

Two numbers on each card keep you from getting lost. The number on the handle is the page's new place in the PDF you will save. The label under the picture, like "Page 7", is its old page number in its own file, and it never changes however often you move the card.

Your original file is never changed, nothing is uploaded, and each page is copied as it is, so text stays sharp and scans keep every detail. The rest of this post covers the parts that trip people up: dragging on a phone, moving pages without a mouse, undoing mistakes, using a page twice, mixing two PDFs and working with very long files.

Dragging pages with a mouse, a finger or a pen

How you drag depends on what you point with:

• A mouse: press anywhere on the card except its buttons, move, and let go. The other cards slide aside to show where it will land.
• A finger: press the dark numbered handle and drag. Touching anywhere else on the card scrolls the page as normal, so you can still move around a long PDF without picking cards up by accident.
• A pen or stylus: works like a finger. Use the handle.

A few habits make dragging painless:

• Work from the front. Put the page that belongs first into place 1, then the next into place 2, and so on. Pages you have already placed stay put while you sort the rest.
• Drag to the edge to scroll. Hold a card near the top or bottom of the window and the page scrolls along with you, so you can carry a card from place 40 up to place 2.
• Go by the pictures for scans. In a scan, "Page 7" only means the seventh picture the scanner saved. Look at the numbers printed on the paper instead.
• Zoom out on a computer (Ctrl and minus, or Cmd and minus on a Mac) to fit more cards on screen for long moves.

On a phone, open the tool in Chrome on Android or Safari on iPhone (we tested in Chromium at phone sizes; Safari should behave the same). The cards sit two or three to a row, and the turn, copy and delete buttons are always shown. The saved PDF goes to Downloads, or on iPhone usually to Downloads in the Files app.

Each card moves on its own; there is no way to select several cards and move them together. For moving a whole block, like an appendix, the guide's section on moving a block of pages has the quickest ways.

The keyboard way: exact moves without dragging

Every move can be made from the keyboard, and on a long PDF it is often quicker and more precise than dragging. Press Tab until a card's numbered handle is selected, then:

• Left or Up arrow moves the card one place earlier.
• Right or Down arrow moves it one place later.
• Home sends it straight to the start, and End straight to the end.

The handle stays selected after each move, so you can press an arrow five times to move a card five places. Screen readers announce each move, such as "Moved to place 3 of 12", and each handle is read out with its old and new page number, like "Move page 7, now page 3 of 12".

A worked example: reversing a whole PDF. Some scanners and feeders save a stack last page first. There is no one-press "reverse" button, but Home does it neatly. Send the card labelled Page 2 to the front, then Page 3, then Page 4, and so on to the last page. Each one goes in front of the pages already moved, so the order ends up fully reversed. With a mouse, drag each one to the first place instead.

Undo and redo: try things without worrying

Every change can be undone, one step at a time, up to 200 steps. A step is any move, turn, copy or delete of a page, and even adding a file: if you added the wrong PDF, one press of Undo takes all its pages away again.

• Undo: the Undo button above the cards, or Ctrl+Z (Cmd+Z on a Mac).
• Redo: the Redo button, or Ctrl+Y or Ctrl+Shift+Z (Cmd on a Mac).

Two things are worth knowing. After you undo, making a new change clears the steps you could have redone, just as in a word processor. And nothing is stored between visits: if you close or reload the tab, the cards and their history are gone. Your original file is safe either way, since it is never changed, but download the new PDF before you close the page.

Also, any change after saving takes the Download button away and brings the Save button back, so the file you download always matches the cards. If you want to keep a version, download it before you carry on.

Copying a page to use it twice

Sometimes a page belongs in two places: a summary that opens and closes a report, a signed declaration needed after two different forms, or a cover sheet in front of each section. Press the copy button (two squares) on the page's card. The copy appears right after it, turned the same way, ready to drag wherever it goes.

Copies cost almost nothing in size. When we copied the first page of a 14-page research paper of 992 KB, the new 15-page PDF was 927 KB, the same as the paper saved with no changes at all. That is because the copy shares its text, fonts and pictures with the original page instead of storing them twice.

A copied page gets its own copies of its links. If the page has form fields, the copy gets its own boxes too, but they are still the same fields: fill in your name on one page and it appears on both. That is usually what you want for a repeated declaration.

Note that copying repeats an existing page. Organize PDF can't add a new blank page, and it doesn't change what is printed on any page.

Combining pages from two PDFs in a new order

Organize PDF can mix pages from several files into one, which Merge PDF can't: Merge keeps each file's pages together. Choose two or more PDFs at once, or press Add pages from more PDFs to put another file's pages at the end. All the pages go into one grid, and each file gets its own colour, shown by a dot under each card and a bar along its top.

A worked example: fronts and backs scanned as two files. Say you scanned five two-sided sheets by feeding the fronts as fronts.pdf, then the backs as backs.pdf. Choose both. You now have ten cards: five fronts, then five backs. Find the back of sheet 1 by its picture and drag it to place 2, the back of sheet 2 to place 4, the back of sheet 3 to place 6, and the back of sheet 4 to place 8. The back of sheet 5 is already last. The same four moves work whether the backs came out first to last or last to first; just go by the pictures. If the backs are upside down too, press each one's turn button twice.

Another common job: a portal wants your form, then your Aadhaar copy, then your certificates, as one file, and you have them as three PDFs. Add all three and drag the pages into the portal's order.

When pages come from more than one file, a few things change:

• The new PDF is named after the file of its first page, and takes its title, author and attached files from that file.
• Each file's bookmarks are kept, one file's after another's, except those pointing at pages you deleted.
• Form fields from every file are kept. If two files use the same field name, the later one is renamed, like Name_2, so each keeps its own answer.
• Tags for screen readers, custom page numbers (page labels) and XFA forms, an older kind of form, are left out.

In our tests, putting a filled-in one-page form in place of the last page of a 14-page paper took 0.2 seconds; the two files, 1.00 MB together, became a 953 KB PDF, and the form kept all 8 of its answers.

Rearranging big documents: what to expect

Long PDFs work, and saving is quick, because pages are copied rather than redrawn. Here is what we measured in Chromium 141 (the browser Chrome is built on) on a 4-core Linux computer with 16 GB of memory. Times are what the page reported:

The textbook's first cards appeared 0.9 seconds after we chose it. You don't wait for every picture: each card's picture is drawn as it comes near the screen, so the first pages appear soon and the rest as you scroll. A card can be moved before its picture appears.

Memory is the real limit. We set no limit on pages or file size, but the whole file and the new PDF are held in memory while it is saved. Saving the 400-page scan took the browser about 2.1 GB more memory than when idle. Phones usually have less to spare than computers, so for files of hundreds of megabytes, use a computer and close other tabs. If the page says the files are too big for the browser's memory, that is the cause.

Moving a long block? Since cards move one at a time, moving 40 pages means 40 moves. For a big block in a long file, it can be quicker to cut the file with Split PDF and join the parts in the new order with Merge PDF.

Checking the new order before you send it

A minute of checking saves an embarrassing re-upload. Before you save:

• Read the Save button. It says Save PDF with 12 pages, or however many there are. If you expected 12 and it says 13, a page was copied or a file added by mistake.
• Compare the handles with the paper. On a scanned document, the numbers on the handles should now match the numbers printed on the pages.

After you download:

• Open the new -organized file, not the original, and scroll through every page.
• See the whole order at a glance in our PDF Viewer: its side panel shows a small picture of every page, and its Bookmarks tab shows whether the bookmarks still lead where they should.
• Expect plain page numbers. Some PDFs show custom page numbers, like i, ii, iii for an introduction. Those are kept only when the order and number of pages are unchanged, so after reordering, your reader shows 1, 2, 3.
• Screen reader users: the hidden tags that help screen readers read a PDF in order are kept only if no page was moved or deleted.

Two more cases: a PDF that needs a password to open must be unlocked before you add it, and a digitally signed PDF no longer carries a valid signature once its pages are rearranged. The guide on bookmarks, links and forms has the full list of what is kept.

Other ways to change page order, and when to use them

• Preview on a Mac shows page pictures in its sidebar, and you can drag them into a new order and save. It is a good choice if you are already on a Mac.
• Adobe Acrobat has full page-organizing tools. If you already use it, it does the job well.
• Online tools that upload your file work too, but your document goes to their server, which matters for statements, ID copies and contracts. Free plans of upload-based tools often cap the file size or the number of tasks.
• Merge PDF is simpler when you only need whole files one after another, like a cover letter, then a resume, then certificates.
• JPG to PDF is the place to fix the order if your pages are still photos: put the pictures in order before you make the PDF.

Organize PDF needs no install and no account, works on phones and computers, and keeps your pages on your own device. Its guide covers putting a scanned document back in order step by step.

Questions people ask next

Can I delete pages at the same time?

Yes. The bin button on a card takes that page out, and Undo brings it back. Our post on deleting pages from a PDF covers blank pages and when Split PDF is quicker.

Can I turn a sideways page while I'm reordering?

Yes. The turn button on a card turns that page a quarter turn right; press it twice for upside down. To turn many pages at once, use Rotate PDF, and see our post on fixing sideways scans.

Can it sort the pages by itself?

No. It doesn't read page numbers or headings, so you set the order. The keyboard tips above make long jobs faster.

Does reordering lower the quality?

No. Each page is copied as it is. We drew every page of our results and compared them with the originals, and they matched; the reordered paper and textbook also had the same words on every page, so their text can still be searched and copied.
