The main difference between a PDF file and an image file is that a PDF file is a digital representation of a printed page, while an image file is an electronic version of a photograph or other visual media. A PDF file can be edited and manipulated in many ways to create different versions with different layouts and designs, whereas an image file cannot be changed after it has been created. Additionally, PDFs are typically more secure than images because they use encryption to protect data.
