In one, you can highlight a sentence, search for a name, or copy a paragraph. In another, dragging across the same-looking words selects nothing at all.</p> <p>The difference is usually not the PDF extension itself. A PDF is a container that can hold several kinds of page content, including actual text and images. A page that looks like printed text may therefore contain computer-readable characters, a picture of those characters, or a combination of both.</p>
