Tools on the Select & Zoom toolbar can change the magnification of PDF documents. Only some of these tools appear on the default view of the toolbar. You can see all the tools by right-clicking the toolbar and choosing either individual tools or Show All Select & Zoom Tools. A few tools are also available on the Page Control toolbar, such as Zoom In/Out and Zoom by value.
To see keyboard shortcuts for resizing the document, open the View > Zoom menu.
The actual size for a PDF page is typically 100%, but the document may have been set to another magnification level when it was created.
Click the Zoom In button or the Zoom Out button in the toolbar.
Enter a magnification percentage in the Common Tools toolbar, either by typing or choosing from the pop-up menu.
Drag the Marquee Zoom tool to define the area of the page that you want to fill the document pane. (View > Zoom > Marquee Zoom)
Drag the Continuous Zoom tool (also called Dynamic Zoom) up to increase the magnification and down to decrease magnification. (View > Show/Hide > Toolbar Items > Select & Zoom > Dynamic Zoom)
When the Marquee Zoom tool is selected, you can Ctrl-click or Ctrl-drag to zoom out. Holding down Shift switches temporarily from the Marquee Zoom tool to the Dynamic Zoom tool.
Choose View > Zoom > Pan & Zoom, or click the Pan & Zoom tool in the Select and Zoom toolbar.
Drag the handles of the box in the Pan & Zoom window to change the document magnification.
Drag the center of the box to pan across the area you want to see.
Click the navigation buttons to move to a different page.
Enter a value in the zoom text box, or click the plus or minus buttons to increase or decrease the magnification by preset levels.
Drag the slider.
Click the plus or minus buttons.
Enter a value in the zoom text box.
You can change the color of the Loupe tool rectangle. Click the Line Color pop-up menu in the lower-right corner of the Loupe Tool window, and select a new color.
Click the Page Thumbnails button in the navigation pane on the left side of the window.
When you zoom in to a high magnification, you may be able to see only part of a page. You can shift the view to show other areas of the page without changing the magnification level.
Use the vertical scroll bars to move up and down the pages or the horizontal scroll bars to move across the page.
Select the Hand tool in the Common Tools toolbar and drag to move the page, as if moving a piece of paper on a table.
Changing the page layout is especially useful when you want to zoom out to get an overview of the document layout. Choose View > Page Display, and select any of the following page layouts:
Single Page View
Displays one page at a time, with no portion on other pages visible.
Displays pages in a continuous vertical column that is one page wide.
Two Page View
Displays each two-page spread with no portion of other pages visible.
Two Page Scrolling
Displays facing pages side by side in a continuous vertical column.
If a document has more than two pages, you can ensure that the first page appears alone on the right side of the document pane. Select either Two Page View or Two Page Scrolling. Also select View > Page Display > Show Cover Page In Two Page View.
You can also display buttons for each of these options in the Quick Tools toolbar by choosing View > > Show/Hide > Toolbar Items > Page Display, and selecting them in the menu.
In Single Page View, choosing Edit > Select All selects all text on the current page. In other layouts, Select All selects all text in the PDF.
You can change the view of a page in 90-degree increments. This changes the view of the page, not its actual orientation.
To temporarily rotate the page view, choose View > Rotate View > Clockwise or Counterclockwise. You can’t save this change.
To save the rotation with the document, choose Tools > Organize Pages > Rotate Clockwise button or Rotate Counterclockwisethe button in the toolbar.
You specify the default initial view settings in the Preferences dialog box. (See Set preferences.)
The PDF opens with the page layout specified in Preferences unless a different page layout is specified in Document Properties (File > Properties > Initial View). The Document Properties setting overrides the Preferences setting. If using Document Properties, be sure to save and close the document for the change to take effect. Acrobat users can change the initial view, unless security settings prevent changes. Reader users cannot change the initial view.
You can view a PDF with the document pane divided into two panes (Split command) or four panes (Spreadsheet Split command).
With Split view, you can scroll, change the magnification level, or turn to a different page in the active pane without affecting the other pane.
The Spreadsheet Split view is useful if you want to keep column headings and row labels visible while scrolling through a large spreadsheet or table. In this mode, changing the magnification in one pane changes the magnification in all panes. Also, scrolling is coordinated between the panes. Scrolling a pane horizontally also scrolls the pane above or below it. Scrolling vertically also scrolls the pane to the left or right of that pane.
To split the view into two panes, choose Window > Split, or drag the gray box above the vertical scroll bar.
To split the view into four panes with synchronized scrolling and zoom levels, choose Window > Spreadsheet Split.
In Split view, click a pane to make it active, and change the zoom level for that pane only.
In Spreadsheet Split view, adjust the zoom level to change the displays in all four panes.
In Split view, click a pane to make it active, and scroll to change that pane only.
In Spreadsheet Split view, click a pane, and scroll vertically to change the views in the active pane and the pane beside it. Scroll horizontally to change the views in the active pane and the pane above or below it.
To restore single-pane view, choose Window > Remove Split.
You can create multiple windows for the same document using the New Window command. New windows have the same size, magnification, and layout as the original window and open at the same page and on top of the original window. When you open a new window, Acrobat adds the suffix 1 to the original filename and assigns the suffix 2 to the new window. You can open multiple windows with the suffix incrementing with each new window. Closing a window causes the remaining open windows to be renumbered sequentially; that is, if you have five windows open and you close the third window that you opened, the windows are renumbered with the suffixes 1 to 4.
This feature is not available when PDFs are viewed in a browser.
Select Window > New Window.
Choose File > Close. You are prompted to save any changes before each window is closed.
