In a typical workday, most of us have to deal with a large number of digital documents in PDF format, in creating, editing and transferring them through the Internet. The PDF is a file format that captures a printed document as an electronic image. These files are useful for documents such as articles, brochures and flyers where one can preserve the original graphic appearance online. A PDF file has one or more than one page images which can be zoomed into or zoomed out from. You can also go page backward and forward with a PDF file.
PDF documents are content rich, as they hold text, different fonts and graphics and make the presentations more interesting and easy to understand. PDF files come with some compression functionality built in, as they are designed to be loaded with graphics and other space consuming stuff. PDF files look like the original document and can be viewed on any computer with any operating system.
A searchable PDF file is a PDF which contains text data that can be searched by using the search function. A searchable PDF contains the original scanned image and a separate text layer from an OCR process. A searchable PDF file comes in handy when one has to deal in large volumes of data. By converting them using OCR into editable and searchable files, one can find any information with an easy search.
A searchable PDF file can be of two types: PDF Searchable Image Exact and PDF Searchable Image Compact. With the Exact method the file size is large but as the name suggests it is very accurate. The page appears exactly as it did when it was scanned, only now it is searchable. With the Compact method the file size is smaller than the exact method and the general look and feel of the original image is retained while it becomes searchable but the quality is not as good as the exact method. A searchable PDF file enables users to look for image data from full text. A searchable PDF can also be stored in the document management system.
