Portable Document Format (PDF) is a universal file format that preserves all the fonts, formatting, graphics, and color of any source document, regardless of the application and platform used to create it. PDF files are compact and can be shared, viewed, navigated, and printed exactly as intended by anyone with free Adobe Acrobat Reader software. You can convert any document to PDF using Adobe Acrobat software.  All of the pleadings in the CM/ECF system are stored in PDF format.
