If the PDF document consists of pages of different sizes, you can use the Crop tool and the Crop Pages dialog box to keep the PDF consistent. You can adjust the visible page area by hiding the area outside your selection. As mentioned earlier, cropping page is simply hiding the information, not removing it, and therefore the file size will not be affected.

  1. Open a PDF file and choose Document > Crop.

  2. Drag a rectangle on the page to crop. To adjust size, drag the corner handles of the cropping rectangle.

  3. Double-click inside the crop area to enter the Crop Pages dialog box or right-click on the page thumbnail and select Crop....

  4. In the Crop Pages dialog box, you can drag the blue frame to adjust your selection and do the following:

    • In the Margin Controls section, view the margin measurements of the cropping rectangle. You may make selections by editing the values in the fields.

    • Check Remove White Margins to crop the page to the boundary. It may be useful when you need to trim presentation slides saved as PDF.

    • Click Set To Zero to restore the crop margins to zero.

    • Click Revert To Selection to revert to the crop area selected with the Crop tool.

    • In the Page Range section, specify the pages to be cropped.

  5. Click OK.
