The .gliffy file extension is associated with diagrams created using Gliffy, a web-based diagramming and flowcharting application. These files store the data representing the visual elements, connections, and text within a diagram. Gliffy diagrams are typically used for creating flowcharts, UML diagrams, network diagrams, organizational charts, and other types of visual representations of information. The .gliffy file itself is not a standalone image file like a .PNG or .JPG. Instead, it contains the structured data that Gliffy uses to render the diagram. To view or edit a .gliffy file, you generally need to open it within the Gliffy application or a compatible tool that can interpret the Gliffy data format. These files are often embedded within Atlassian products like Confluence and Jira, allowing users to create and collaborate on diagrams directly within those platforms. The data within a .gliffy file is typically stored in a proprietary format, although some tools may offer options to export diagrams to more standard formats like SVG or PNG for wider compatibility.
