PDF stands for Portable Document Format, which is prevalent during daily use. We may need to create a PDF document from existing files, but sometimes the source happens to be an image or a scanned copy. Then, you will surprisingly find out that the newly created PDF document cannot be copied, nor can it be searched. Why? Because no content can be searched within the file.
