pdf stands for portable document format. introduced by adobe systems in 1993, it enables users to view and print documents of anykind, regardless of computer platform. it also supports encryption, enhancing information security.
pdf is popular for many reasons. the primary benefit of using pdf is that it helps preserve data integrity. it doesn’t matter if you’re opening or reading a pdf or if you’re sending it to someone else―if someone sent it to you as a pdf, it will look the same recreated anytime. pdf also allows users to display diverse sorting and reading events without changing the forms, its layout and its programming. it also offers solutions for linking and bookmarking.
pdf documents aid users in keeping important information intact. for example, if you have a contractual pdf document, the content cannot be changed or altered in any form, ensuring information security even after it’s been electronically sent and represented as a paper-based copy. therefore, it eliminates the need for manual sign-offs and keeps every binding agreement valid.
so if you ever need to share a document, either for personal or for business, include copyrights and reference tables, or to simply show a concise filing system with data insecurity, pdf will do the job. moreover, with adobe acrobat pro, you can now easily sign any pdf with ease.
