It allows users to create and edit PDF documents, which is a widely used and accepted file format for electronic documents.It has a wide range of tools and features that make it easy to edit and format text, images, and other elements in a PDF document.It allows users to add comments, annotations, and signatures to PDF documents, making it a useful tool for collaboration and review.It has a user-friendly interface that is easy to navigate and understand, even for those who are not tech-savvy.It is compatible with both Windows and Mac operating systems, and can be used on a variety of devices, including desktops, laptops, and mobile devices.It also allows user to convert PDF files to other formats like word, excel, powerpoint and others.It also allows user to Secure the PDF files with password protection and digital signature.

dobe Acrobat is a paid software and can be costly for some users, especially for those who only need to use it occasionally.It can be difficult for some users to learn and master all of the advanced features and tools that it offers.The software can be quite resource-intensive, which can slow down older computers or devices.It does not include all the features of other Adobe products like Adobe Illustrator, Photoshop etc.It has a steep learning curve for some users, especially those who are not familiar with PDF editing and formatting tools.It requires an internet connection to validate the license and can sometimes be a problem while working offline.There are some alternatives available like Foxit PhantomPDF, Nitro Pro etc which may be less expensive and offer similar functionality.

Standards are a good thing and PDF is the de facto standard for regular documents and Adobe Acrobat Reader is free and the pre-eminent PDF reader, it's use is a no brainer.

Adobe Acrobat Pro is needed for PDF creation or adhoc free editing. Acrobat Pro is too expensive for a casual user. Therefore typically only a few workers for whom document creating/editing is an essential part of their job have a Acrobat Pro license.

I've used Acrobat for decades and I'm glad to see it is now so very mainstream. Most everyone knows what a PDF file is and can read it as, if they don't have the actual program installed, most browsers and graphic editors can usually read them.

With the free reader, if you want to make any other than the most basic of changes, unless the file has been purposefully created as a fillable form, it is difficult/impossible to edit anything and the software nags you to pay in order to do so. But can't blame Adobe for that, they have to make their money too!
