Adobe Reader Ubuntu

Adobe Acrobat Reader is a family of web services and application software which is developed by Adobe Inc. for viewing, creating, manipulating, printing, and managing Portable Document Format (short for PDF) files.

The family contains Acrobat Reader (formerly called Reader) Acrobat (formerly called Exchange) and Acrobat.com. The common Acrobat Reader is a freeware that is available for various mobile and desktop platforms.

It supports annotating, printing, and viewing PDF files. Additionally, "Premium" services are also accessible on a paid subscription. Acrobat.com aggregates the family along with the range of file hosting services and enterprise content management. The commercial proprietary Acrobat can also convert, edit, create, digitally sign, publish, export, and encrypt PDF files and it is available for macOS and Microsoft Windows only.

Purpose of Adobe Reader

The primary function of Adobe Reader is editing, viewing, and creating PDF documents. Also, it can import famous image and document formats and store them as PDF. It is possible for importing the output of a scanner, Windows clipboard contents, or a website.

However, when a document of PDF is created, its original flow and organization can't be modified meaningfully due to the nature of the PDF. Adobe Reader is to change the contents of images and paragraphs, but doing so doesn't recheck the entire document for accommodating a shorter or longer document. Acrobat can change the order of the PDF pages, crop them, manipulate hyperlinks, add comments, digitally sign PDF files, edit many PDF file parts, and ensure its loyalty to such standards as PDF/A.
