Assessor Image File Formats

The Pima County Assessor's Office is currently working to convert documents within this web site to a standard Adobe® PDF file format. However due to the volume of image data, available funding and other technical considerations, you may find images in any of the following 3 formats while the conversion is in progress throughout this site.

  • Adobe® PDF
  • TIFF (Tagged Image File Format)
  • AutoCAD DWG

As a result, you must install and use a browser plug-in—similar to those required to access Adobe® PDF files, RealPlayer®, or Macromedia Flash® files—on your workstation in order to view these files directly. An alternative method is to use third-party software or services to view these images either directly or after conversion to another format, such as Adobe® PDF.

Unfortunately, the Pima County Assessor's Office can not provide direct user support on viewing images beyond providing hyperlinks to known working plug-ins.

To View AutoCAD DWG Files:

AutoCAD drawing formats store electronic maps (DWG files). DWG files are the standard format that AutoCAD uses to save drawings. They contain all the drawing information, including information not needed to simply browse the image.


Download and install Autodesk DWG Viewer here.
