Cropping a PDF can be useful for a variety of reasons, such as removing unwanted margins or trimming a specific section of a page. Adobe Acrobat Reader DC provides a simple and effective way to crop a PDF document.

1. To begin, open the PDF in Acrobat Reader DC and select the “Edit PDF” tool from the right-hand menu. From there, select the “Crop Pages” option. This will bring up a crop box around the edges of the page.
2. To crop the page, simply click and drag the handles of the crop box to adjust the size and position of the cropped area. The dimensions of the crop box can also be adjusted manually by entering values in the “Width” and “Height” fields.

Alternatively, you can choose to crop specific pages by selecting the “Selected Pages” option and entering the page range you wish to crop.

The “Crop Pages” option allows for precise adjustment of the crop box, and the tool can be used on a single page or multiple pages at once.

#4 How to crop a PDF with GIMP

GIMP is a free and open-source image editing software that can also be used to manipulate PDF files. While GIMP is primarily designed to edit raster images, it can import PDF files and allow users to edit individual pages within the document. One of the most common tasks users might want to do with a PDF is to crop it, removing unwanted borders or whitespace around the edges of a page. In this paragraph, we will explore how to crop a PDF using GIMP.

Step 1: Open the PDF file in GIMP

In the “Import from PDF” dialog box that appears, select the page or pages you want to edit, then click “Import.”

Step 2: Select the crop tool

With the PDF page now open in GIMP, select the “Crop Tool” from the toolbar on the left-hand side of the screen. The crop tool is represented by a small square with a diagonal line through it. Alternatively, you can press “Shift + C” on your keyboard to activate the crop tool.

Step 3: Define the crop area

Click and drag your mouse over the PDF page to define the area you want to keep. You can adjust the size and position of the crop area by clicking and dragging the handles on the edges of the selection box. Alternatively, you can enter precise values for the crop area in the “Tool Options” panel at the bottom of the screen. Once you are satisfied with the crop area, press “Enter” on your keyboard to apply the crop.

Step 4: Export the cropped PDF

With the PDF page now cropped, it’s time to save the edited file. Click on “File” in the top left corner of the window and select “Export As.” In the dialog box that appears, choose a name and location for the cropped PDF file and select “PDF” as the file type. If you want to keep the same resolution and other settings as the original PDF, make sure the “Use export settings from last export” box is checked. Finally, click “Export” to save the cropped PDF file.

While GIMP is primarily designed for editing raster images, it can also be used to manipulate PDF files. Cropping a PDF in GIMP is a relatively simple process that involves opening the file, selecting the crop tool, defining the crop area, and exporting the edited file.
