Why People Use PDFs?
Adobe® Portable Document Format (PDF) is an industry standard adopted by governments and enterprises worldwide. Adobe PDF is a reliable format for electronic document exchange that preserves document layout and formatting so files can be viewed and printed on a variety of platforms. Here are 8 reasons why People use PDFs:
PDF files can be created easily by any application that can print: Word-processors, spreadsheets, CAD software, scanned pages, photographs – any source content may be converted to PDF. PDF reading software, such as Adobe's Reader and its many competitors, is ubiquitous since the very beginning of PDF. So people can view and print any PDF files free.
The portability makes PDF the popular format to share information. Of cause, you can send a Word, HTML, PowerPoint or any other file. But other formats, while just as easy to attach to an email, aren't quite as easy to share as PDF. They might not look quite the same when opened on different machines, or can't be opened on a Mac. There may be font dependencies, or differing page-sizes or other application or user settings that affect appearance. First and foremost, you can't be sure the recipients have the same version of PowerPoint (or whatever you are sending). You may not want to give them the ability to edit the document, but you don't want hassle with passwords. Making a PDF is usually just a click or two, and for that amount of effort, it's clearly a smart move.
PDF files are ideal vehicles for content that's intended for limited distribution. Most PDF creation and manipulation software can add password protection to PDF files, and even include password-protected attachments.
The natural self-containment of PDF files, along with other technical characteristics makes it possible to use certificates and digital signatures with PDF files and PDF Portfolios to address operational and archival authentication needs for governments, corporations and other institutions. The digital signature mechanism for PDF is fully specified in ISO 32000-1, and is available to any software developer.
PDFs may contain a wide variety of other features; navigation bookmarks, fillable forms, annotations, metadata, digital signatures to guarantee authenticity, and much, much more that HTML simply isn't equipped to do.
In addition, PDF includes detailed management of all sorts of document functions, navigation features, accessibility and more, and it's all just ready to go, for users on every platform, inside of each and every PDF file. PDFs are usually smaller than the files used to create them, so they are easier to email and download. Although hard-drives are getting larger and larger, a 195kb PDF file is usually preferred over a 2.95 MB Word file, especially if users aren't expected to edit it.
