What Is a PDF File

PDF is short for Portable Document Format. A PDF file includes all the components of a printed document encoded as an electronic image, and you can navigate, print, or send PDF to another person.

Dr. John Warnock, a co-founder of Adobe Inc, developed this file format. The PDF files were created to allow anyone to download documents from any application, transfer electronic copies of those documents anywhere, and view and print those documents on any computer.

This file format has become very popular nowadays, and PDF files are actually the image of documents. A PDF file has one or more page images that the user can zoom in or out. A PDF's pages can also be scrolled through backward and forwards.

What Are the Differences Between PDF and JPG

In short, PDF is a document format, and JPG is an image file format. Although both two formats can contain photos, they are totally different:

  • JPG files are relatively small because they compress image data only. Users may lose image data when they save JPG files, and this kind of data loss will not happen if you are using a PDF file format.
  • Although PDF files are not easy to edit, you still have ways to edit them. On the other hand, JPEGs cannot be broken down into parts since they compress all content into a single layer.
  • You could choose JPGs over PDFs due to their smaller size since they will likely take up less space on your hard drive, portable disk, or cloud. However, the storage of papers and photos may be more dependable with PDF files.
