The need for searchable PDF files
PDF files can contain images and text. When the files contain text, it is important to be able to actually work with the text, in addition to simply viewing it. With searchable PDF files, you can instantly search for the specific passages that you need, and you can also copy and edit the text. This is especially important for scanned PDF files, which are initially processed only as images.
Converting scanned PDF files
When a file is scanned into a computer, it is initially entered as a TIFF image file, regardless of whether or not the original document contains any text. The next step is to convert it into the most appropriate format and make it text-searchable. Once a file has been converted into PDF, you can make it searchable with the help of OCR software, which automatically recognizes all of the text within a file.
