Nowadays, people use PDFs on a large scale for reading, presenting, and many other purposes. And many websites store data in a PDF file for viewers to download instead of posting on the web pages, which brings challenges to web scraping. You can view, save and print PDF files with ease. But the problem is, PDF is designed to keep the integrity of the file. It is more like an “electronic paper” format to make sure the contents would look the same on any computer at any time. So it is difficult to edit a PDF file and export data from it.
