About creating Adobe PDF files
You can convert a variety of file formats to Adobe Portable Document Format (PDF), a
universal file format that preserves all the fonts, formatting, images, and color of a source
file, regardless of the application and platform used to create it. Adobe PDF files are
compact and can be exchanged, viewed, navigated, and printed by anyone with free
Adobe Reader software, while maintaining document integrity.
In addition to creating Adobe PDF files from virtually any software application, you can
create PDF files in Adobe Acrobat by scanning and capturing paper documents and by
downloading and converting web pages.
There are many ways to create Adobe PDF files, and the amount of structural information
the PDF files contain depends on how they are created. The more structural information a
PDF document contains the more opportunities you have for successfully reusing the
content and the more reliably a document can be used with screen readers. (See
Understanding how tags affect accessibility.)
For many users, the process for creating Adobe PDF files is almost automatic. Most users
need only be aware that the settings used in the conversion process can be customized
should the quality or size of the Adobe PDF files need to be changed. Other users, because
of their heavy use of images, fonts, and color, for example, routinely prefer to customize
the conversion settings to create the best possible Adobe PDF file for their needs.
