Extract text from PlantUML diagrams (PU)
To convert PU diagrams to another format, you need PlantUML or other Developer software.
To convert other file formats to the "Diagram Source Code" file type, you need software like PlantUML or a similar tool.
The .PU file extension primarily represents a plain text file containing PlantUML diagram source code. Developers use PlantUML to write structural and behavioral diagrams - such as sequence, class, or use case diagrams - using a fast, human-readable language. A secondary use for .PU files is as JSON-formatted map files for the Perchance University MUSE (Multi-User Simulated Environment) game.
The main disadvantage of a .PU file is that it is raw code, not a visual image. To view the actual diagram, users must install Java, download the PlantUML compiler, or configure a specific IDE plugin like those for VS Code. You cannot natively open it in a web browser, standard image viewer, or word processor. Non-technical users cannot read the raw text structure effectively.
To make the diagram accessible to clients or teammates, you must convert the .PU text into a raster or vector image. The most common target formats are PNG for quick web viewing, SVG for lossless scaling and web embedding, and PDF for document inclusion.
Standard online image converters usually fail to process .PU files because they lack the specific PlantUML rendering engine and expect raw pixel data instead of text instructions. Since our analysis detects standard text or underlying JSON data, viewing the internal content is immediate.
Convert.Guru analyzes your PU file, detects the exact format, and lets you read the text inside.
Users also converted PLANTUML, PUML and MG files.
If you want to convert PU file to MG, TXT, RTF, DOC, DOCX, ODT, PAGES, TEX, LATEX, MD, MARKDOWN or LOG, you can use PlantUML or similar software from the "UML Diagram Source Code" category. In the File menu, look for Save As… or Export….
To convert PDF, DOC, ASC, TODO, NFO, MEMO, README, DOCX, JPG, TXT, NOTE or RTF files to PU, try PlantUML or another comparable tool in the "UML Diagram Source Code" category.
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 PU converter.
