Dia is an open-source diagramming application available for Windows, Linux, and macOS. A .shape file defines a shape that Dia can add to its shape palette. Custom shapes are available from Dia's shape repository.
The file belongs to Dia's custom-shape system and is used when building diagrams; it does not store a finished diagram. It is a Dia-specific resource, not a general-purpose image or diagram interchange file.
To use the shape, place the .shape file in Dia's custom-shapes directory, then restart Dia Diagram Editor. Dia loads installed shapes into its palette; the file is not a standalone diagram to open as a drawing.
A .shape file has no useful standalone conversion because it defines a Dia shape rather than storing a finished image or diagram. To create an exportable result, use the shape in a Dia diagram and export the diagram from Dia.
