Features of PDF
The main purpose of this defining format was to facilitate simple distribution and printing of documents without alterations to their layout, fonts, images, and text. PDFs, therefore, turned out to be by far the most effective means of electronically sending documents since no matter what computer, screen, or operating system you send a PDF file through, its appearance never changes. Some attractive features these days for any kind of document service are packed into PDF.

What Made PDF Popular?
Popularity gained by PDF because it provided solutions to those two big interfacing problems, document format, and compatibility. This is, however, an amazing level of precision and security in that a computer file prints equally from a Windows PC and misaligns on an iMac or misaligns on an iPhone. This is exactly the reason why PDF became the number one choice when sharing any important files.
PDF (Portable Document Format) is the universal file format that keeps a document safe, secure, and the same for every user. PDF not only spans from notes and books to forms and official documents, but has also been trusted for sharing and printing documents across the globe. For viewing or opening this file type in any apparatus, a PDF reader makes it accessible to students, teachers, and professionals, thus making it an effortless mode of working, studying, and communicating.
