Adobe Reader


Adobe Reader is not an authoring program. You can't create PDFs. You can't use the program to edit and save PDF documents. And if you fill in a form, you can't save the added field data. However, with the introduction of Acrobat 7 and Adobe Reader 7, an Acrobat Professional user can issue certain usage rights to a PDF document that permit an Adobe Reader user to make edits and save an edited file. Usage rights are restricted to comments and markups, and they are permitted only on a document that was saved in Acrobat Professional with usage rights enabled.

While working in Adobe Reader, be aware that not all tools and editing capabilities appear for every file you open in Adobe Reader. Usage rights for additional features are enabled on a document-by-document basis.

PDF documents can be created for specific purposes such as for prepress and printing, document archival, engineering drawings, and documents suited for many different industries. Although you can't create PDFs in Reader, you can view all PDFs created for any purpose. Some PDF documents are created using subsets of the PDF format. They remain PDFs but they are specially designed documents meeting certain standards for particular purposes. As an example, the PDF/X format is designed for professional printing. The PDF/A format is designed to preserve documents in an archived file. Fortunately, Adobe Reader can view and print PDF files meeting these standards.

Understanding PDF Subsets

After the introduction of the PDF format in 1993, many industries adopted that file format standard. Creative professionals began to use the format to send documents to commercial printers for prepress and printing. Government began to use the format for distribution of documents to constituentsthe most obvious governmental use is with the U.S. Internal Revenue Service, which distributes tax forms for online filing. Engineers began to use the format for archiving drawings, schematics, and other, similar documents. The legal industry began to archive legal documents and use Acrobat search capabilities to research documents related to court decisions.

As PDF became standardized in so many industries, the scope of the format made it clear to many people that certain standards needed to be imposed for PDF itself. As a result, an international standards committee (the International Standards OrganizationISO) began to implement subsets of the PDF format for certain file types used by specific industries.

The PDF/X format was developed for the creative professional. PDF/X is still a PDF document, but it contains document structure and content optimized for printing files on commercial devices. Next came the PDF/A format, designed for archival purposes. Once again, the ISO set forth standards for the PDF/A format to ensure that the files of today will be recognized by users a decade or a century from now.

Although Adobe Reader can't create PDF documents or convert existing PDF files to one of the format subsets, Adobe Reader can view and print all forms of PDF.
