Adobe Acrobat software allows you to convert files of many types to PDF format, and you can create PDF files from scratch. PDF files retain the content, formatting and document information of source files and can be viewed on almost all operating systems, making PDF a proper format when you want to share electronic information consistently on all platforms. You can also work with PDF files in a number of ways, including adding images to a PDF. You can insert a copy of a GIF file, which retains its original resolution, into a PDF page.
Open the PDF in Adobe Acrobat, click "Tools," select "Advanced Editing" and choose "TouchUp Object Tool."
Right-click the PDF and select "Place Image" from the pop-up menu. The Open dialog box appears.
Select "Compuserve GIF" from the "Files of type" drop-down box.
Navigate to the location of the GIF file, click it to select it and click the "Open" button. A copy of the GIF file appears in the center of the PDF page.
