Part 4: FAQs about How to Crop a PDF on Mac

1Do you lose the quality of the PDF on Mac when cropping?
Cropping or removing only a portion of a PDF, has no effect on the quality of the PDF documents. If you print or show the cropped page at the same size as a page from the entire sensor, however, it will not appear as nice, simply because it contains far less information.
2Does cropping PDF reduce file size?
No. Cropping a PDF does not result in a reduction in file size since data is only concealed, not deleted. You can return the page and its content to its original state by resetting the page size. But if you only cut out the desired part, it should be much smaller than the original PDF.
3Is there an easy alternative to crop a PDF on Mac?
Yes. When you need to crop a PDF on Mac, you can use the snapshot tool to cut out the desired part and save the screenshot in PDF format. Moreover, you can also further edit the PDF documents before sharing or saving them on your MacBook.


As you are aware, you will require the appropriate tool to crop your PDF document on Mac appropriately. PDFelement is the all-in-one tool to remove the margins of the PDF document and edit the PDF with advanced features. Just download the program to find out whether it works now.
