What is a CIT file?
A .CIT file is most commonly an Intergraph CCITT Image or a CAD design drawing file originally used by mapping and CAD software like MicroStation. These files usually store raster image data for architectural, engineering, or geographic projects.
However, the .CIT extension has multiple different uses across various software systems. It can be a CitectSCADA project file managed by AVEVA Plant SCADA, or a PLC compiled program file for automation software like Codesys. It may also appear as a CALS raster image file generated by Océ scanning systems, or as a Cite Report Project file created by In8.
How to open CIT files?
Because a .CIT file can be a CAD raster image, a SCADA project configuration, or a PLC program, you must know its exact type to open it correctly. viewer.online/cit analyzes .CIT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If the file is an image-based format, you can typically view it using CAD viewers or imaging software that supports Intergraph or CALS standards. If the file is a project configuration, it might open in Microsoft Project or a simple text editor depending on its internal structure.
File conversion
If you need to share your .CIT image file with users who do not have specialized CAD software, you should convert it. We recommend using convert.guru to convert image-based .CIT files into sensible target formats like .TIFF, .PNG, or .JPEG.
Summary
viewer.online/cit directly opens and previews .CIT files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
