However, that means you can’t work with the text. It took an image of the text and displayed it. That’s why we invented the Portable Document Format (PDF), to present and exchange documents reliably - independent of software, hardware, or operating system.The goal was to enable anyone to capture documents from any application, send electronic versions of these documents anywhere, and view and print them on any machine.Įarly PDFs were image-only. That was Adobe’s mission when they created the pdf file format, according to their website: Everybody can open and view the content and it gives us a consistent view regardless of device or software.
Most of us use PDF files all the time without giving them too much thought.
