Extract text from FX Graph 3 files (FG3)
To convert FG3 graph files to another format, you need FX Graph or other Data software.
To convert other file formats to the "Mathematical Graph File" file type, you need software like FX Graph or a similar tool.
The .fg3 file format is a proprietary document generated by FX Graph, a mathematical graphing utility developed by Efofex Software. These files store parameters, mathematical equations, and visual settings for plots. They are primarily used by math and science educators to generate diagrams for tests and worksheets.
The primary disadvantage of the .fg3 format is its strictly proprietary nature. You cannot open these files natively in standard image viewers, vector editors, or web browsers. Anyone receiving an .fg3 file must have an active subscription and a local installation of the Efofex software suite. This creates severe compatibility hurdles when sharing educational materials with students or unequipped staff.
To resolve these sharing limitations, users must convert the .fg3 file into standardized formats. The ideal conversion targets are SVG or EMF for scalable vector integration into document editors like Microsoft Word. Alternatively, PNG or PDF are excellent choices for universal viewing and printing.
Because .fg3 is a closed, undocumented file type, standard online converters typically fail to process it. The file does not store actual image pixels; it stores the mathematical instructions required to draw the graph, relying entirely on the original software's proprietary rendering engine. If our analysis detects a supported underlying structure or embedded thumbnail, viewing or partial conversion may still be possible.
Convert.Guru analyzes your FG3 file, detects the exact format, and lets you read the text inside.
If you want to convert FG3 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use FX Graph or similar software from the "Mathematical Graph Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to FG3, try FX Graph or another comparable tool in the "Mathematical Graph Storage" 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 FG3 converter.
