Click the thumbnails to select the pages or images you want to open. Shift-click to select more than one page or
image. The number of selected items appears under the preview window. If you’re importing images, skip to step
8.
Note: Use the Thumbnail Size menu to adjust the thumbnail view in the preview window. The Fit Page option fits one
thumbnail in the preview window. A scroll bar appears if there are multiple items.

To give the new document a name, type it in the Name text box. If you’re importing more than one page or image,
multiple documents open with the base name followed by a number.

Under Page Options, choose from the Crop To menu to specify what part of the PDF document to include:
Bounding Box
Crops to the smallest rectangular region that includes all the text and graphics of the page. This option
eliminates extraneous white space and any document elements outside the Trim Box.
Note: Bounding Box will not crop white space that is part of a background created by the source application.
Media Box
Crops to the original size of the page.
Crop Box
Crops to the clipping region (crop margins) of the PDF file.
Bleed Box
Crops to the region specified in the PDF file for accommodating limitations inherent in production
processes such as cutting, folding, and trimming.
Trim Box
Crops to the region specified for the intended finished size of the page.
Art Box
Crops to the region specified in the PDF file for placing the PDF data into another application.

Under Image Size, enter values (if necessary) for Width and Height:
•
To preserve the aspect ratio of the pages as they’re scaled to fit within the rectangle defined by the Width and Height
values, select Constrain Proportions.
•
To scale the pages exactly to the Width and Height values, deselect Constrain Proportions. Some distortion might
occur when the pages are scaled.
When more than one page is selected, the Width and Height text boxes display the maximum width and height values
of the selected pages. All pages are rendered at their original size if Constrain Proportions is selected and you don’t
change the Width and Height values. Changing the values will scale all pages proportionately as they're rasterized.

Specify the following options under Image Size:
Resolution
Sets the resolution for the new document. See also “
About pixel dimensions and printed image resolution
Mode

Bit Depth

The Width and Height values plus the Resolution determine the final pixel dimension of resulting document.
