Pages

0 pagesLong-press to select

Arrow keys move between pages. Shift with an arrow key extends the selection. Space or Enter opens a page. Alt with an arrow key moves the selected pages.

Rearrange the pages of a PDF

Open a PDF and every page appears as a thumbnail you can pick up and move. It works the same for one file or several, and the pages are rearranged on your device.

  1. Open your PDF

    Choose or drop the file. Make the pages smaller for an overview, or larger to read them.

  2. Move the pages

    Drag a page to its new place. Select several to move them together, even from one file into another.

  3. Download the result

    Download the rearranged PDF, or select some pages and download only those.

Ways to move a page

Drag
Pick up one page, or select several and move them together.
Select
Click, Ctrl or ⌘ click, Shift click, or drag a box around pages. On a touch screen, long-press a page.
Keyboard
Alt with the left or right arrow moves the selected pages earlier or later.
Page number
Open a page, press M and type the position it should move to.
Start or end
A file's menu moves its whole group of pages to the start or the end in one step.
In the preview
The thumbnail strip beside an open page can be dragged too, so you can reorder while you read.

Your files stay on your device

Many online PDF tools upload your files to a server to work on them. docstack does the work in this browser tab instead: files are opened, converted, arranged and merged on your device, and no file or page is sent anywhere. There are no analytics and no trackers.

You can check this yourself. Once the page has loaded, turn off Wi‑Fi and keep working: PDFs and images still open, rearrange and download.

There is one download to know about. The first time you add a PowerPoint or Word file, your browser fetches the tool that converts it (about 50 MB) from ZetaOffice. The file itself is still converted on your device.

Common questions

Can I move several pages at once?

Yes. Select them, then drag any one of them and the whole selection moves together.

Can I undo a move?

Yes. Undo and redo cover every change, and each confirmation has an Undo button.

Does reordering change the pages themselves?

No. Pages are copied into the new PDF as they are, so text stays selectable.

Can I rotate or delete pages too?

Yes. Select the pages, then press R to rotate them or Delete to remove them.
