You can adjust the visible area in a PDF using the Crop Pages tool and the Set Page Boxes dialog box. Cropping pages can help you create consistency within a PDF composed of pages of different sizes.
Note:
Cropping does not reduce file size since the cropped data is only hidden and not discarded.
Try it in the app
Crop PDF pages and trim page margins in a few simple steps.
To crop a page:
-
From the top tools bar, select Edit. Alternatively, select the All tools menu > Edit a PDF.
It displays the Edit toolset in the left panel.
-
From the Edit tools menu, select Crop page
.
-
Drag a rectangle on the section that you want to crop. If necessary, drag the corner handles of the cropping rectangle until the page is the size you want.
-
Double-click inside the cropping rectangle.
-
In the Set Page Boxes dialog that opens, modify the following settings as desired.
- Show All Boxes (Acrobat Pro) - Shows the black, red, green, and blue rectangles indicating the CropBox, ArtBox, TrimBox, and BleedBox on the preview. When two (or more) margins coincide, only a colored line appears.
- Margin Controls for:
- CropBox - Defines the boundary for the contents of a page when it’s displayed or printed.
- ArtBox (Acrobat Pro) - Defines the meaningful content of the page, including white space.
- TrimBox (Acrobat Pro) - Defines the finished dimensions of the page after trimming.
- BleedBox (Acrobat Pro) - Defines the clipping path when the page is printed professionally to allow for paper trimming and folding. Printing marks may fall outside the bleed area.
- Constrain Proportions - Locks the proportions of the crop so that all margins are at the same distance.
- Remove White Margins - Crops the page to the artwork boundary. This option is useful for trimming the edges of presentation slides saved as PDFs.
- Set To Zero - Restores the crop margins to zero.
- Revert To Selection - Reverts to the crop margin selected with the Crop Page tool.
To apply these settings to more pages, set the page range or select All under Page Range.
-
Select OK.
To remove white margins:
-
From the All tools menu, select Use Print Production.
It displays the Print Production toolset in the left panel.
-
From the left panel, select Set Page Boxes.
-
In the Set Page Boxes dialog that opens, under Margin Controls, select Remove White Margins.
-
To remove white margins from more pages, set the page range or select All under Page Range.
To undo cropping:
-
From the All tools menu, select Use Print Production.
It displays the Print Production toolset in the left panel.
-
From the left panel, select Set Page Boxes.
-
In the Set Page Boxes dialog that opens, under Margin Controls, select Set to Zero.
Cropping a PDF does not reduce file size because information is merely hidden, not discarded. By resetting the page size, you can restore the page and its content to its original condition.
