About UML files
A .UML file is not an image you can view directly; it is a structured data file containing the code or XML definitions for a Unified Modeling Language diagram. These files are typically text-based (using XMI or PlantUML syntax) and describe software architecture, actors, classes, and relationships in a format that only modeling software can understand.
Because they are raw data, you cannot double-click a .UML file to see the diagram in a standard photo viewer or web browser. To share these diagrams with stakeholders or include them in reports, you must convert them into visual formats like PDF, PNG, or SVG.
Convert.Guru analyzes your UML file, detects the exact format, and lets you read the text inside.
If you want to convert UML file to IMAGE, PDF, CODE, PNG, DRAWIO, JS, TS, PY, JAVA, CPP, C or CS, you can use StarUML or similar software from the "Software Architecture Diagram" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to UML, try StarUML or another comparable tool in the "Software Architecture Diagram" category.
The UML Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our UML converter.
