How to Crop a PDF on Mac (2 Free Ways)

PDF files are easily sharable because they can be opened on any device, on any platform including macOS. But while opening and reading PDF documents can be very easy, the same cannot be said for editing a document. You will find that you need separate software to make any changes to the document.

If for instance, you wanted to crop a PDF on Mac, you may have a hard time finding the right tool to do it. Even if you can find the right solution, most people find it very difficult to crop a PDF document on Mac. Here, we will be looking at two very effective ways to crop a PDF on Mac.

Why You Need to Crop PDF on Mac

One of the main reasons why you may need to crop a PDF document is to resize it to prepare it for printing. This is where cropping can help to resize the margins of the document and get it just the right size for the type of printing paper that you intend to use.

Cropping tools can also be an ideal way to re-orient a PDF document, depending on what you would like to use it for. You can use them to crop and rotate a PDF document into a vertical orientation or a landscape layout that may be more ideal for PDFs that you intend to use in a PowerPoint presentation.

Cropping is also one of the best ways to get your PDF and the elements on it to just the right size. They allow you to resize the document or aspects of the document to get the right size depending on the content. For example, you can use various cropping tools to crop the images on the document.

The following is a breakdown of the main reasons you may want to crop a PDF:

  • Cropping can help you remove confidential information from a PDF that you'd like to share
  • It is also a good way to highlight important aspects of the PDF
  • You can also use cropping to divide a PDF into smaller files to make it easier to share.
  • It is also a good way to remove any merged paged from a PDF file

Whatever the reason, the following solutions will help you to easily crop a PDF on Mac for free.
