Convert ST7 files online for free
The converter easily converts your ST7 file to various formats - free and online. No Strand7 or or other Cad software needed.
To convert other file formats to the "FEA Model or CCD Image" file type, you need software like Strand7 or a similar tool.
The .ST7 extension primarily refers to a structural analysis model created by Strand7, a high-end Finite Element Analysis (FEA) system. These files store complex mesh geometry, material properties, and load cases used by civil and mechanical engineers. The main challenge with .ST7 files is their proprietary nature; they are strictly locked to the licensed software environment, making them impossible to open without a costly active subscription or a hardware dongle. Engineers often need to bridge this gap by converting geometry to neutral CAD formats like STEP or IGES for use in AutoCAD or SolidWorks, or by exporting results to PDF for client reports.
Alternatively, an .ST7 file may be a legacy astronomical image captured by ST-7 series CCD cameras from SBIG (now Diffraction Limited). These raw or compressed image files contain scientific data that standard photo viewers cannot interpret, often appearing as corrupt files or black squares. For these users, the goal is typically converting the scientific data into standard FITS files for astronomical analysis or common raster formats like TIFF or JPG for publication and web sharing. Whether you are dealing with engineering simulations or astrophotography, convert.guru helps you identify the format and convert it to a usable standard.

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 ST7 converter.
