Convert SIMP to another file type
To convert SIMP projects to another format, you need Software Ideas Modeler or other Developer software.
Convert a file to SIMP
To convert other file formats to the "UML Diagram Project" file type, you need software like Software Ideas Modeler or a similar tool.
About SIMP files
A .simp file is a project file created by Software Ideas Modeler, a computer-aided software engineering (CASE) tool. It stores visual architecture models, including UML diagrams, SysML, entity-relationship diagrams (ERD), and flowcharts. The internal structure of the file relies entirely on XML data.
The file is designed to be opened and edited exclusively with Software Ideas Modeler. While the underlying code is plain text, reading the actual visual layout requires this specific software.
The main disadvantage of the .simp format is its proprietary use case. If you share this file with clients, stakeholders, or other developers who do not have the software installed, they cannot view your diagrams. Standard web browsers, document readers, and image viewers cannot interpret the proprietary XML schema to draw the shapes.
To share your models effectively, you must convert the .simp file to standard visual or document formats like PDF, PNG, or SVG. Exporting to these targets ensures the diagrams are viewable on any device, though you will permanently lose the ability to edit the interactive structural data.
This file format is notoriously difficult to convert externally. Rendering the custom XML schema into an accurate visual diagram requires the original software's proprietary rendering engine, meaning standard online converters almost always fail to process it.
Convert.Guru analyzes your SIMP file, detects the exact format, and lets you read the text inside.
If you want to convert SIMP file to INDD, QXP, PUB, PMD, PM6, PM7, PM8, PM9, PM10, PM11, OMP or P65, you can use Software Ideas Modeler or similar software from the "Software Modeling Project" category. In the File menu, look for Save As… or Export….
To convert MDI, PUB, PDP, PM4, P65, COMIC, WEBTEMPLATE, PMD, SPUB, INDD, PM5 or QXP files to SIMP, try Software Ideas Modeler or another comparable tool in the "Software Modeling Project" category.
The SIMP 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 SIMP converter.
