Extract text from WEG PLC function blocks (GFB)
To convert GFB function blocks to another format, you need WEG Programming Software or other Developer software.
To convert other file formats to the "PLC Logic Block" file type, you need software like WEG Programming Software or a similar tool.
The .GFB file extension primarily denotes a PLC function block file used by WEG Automation. These files contain logic routines, parameters, and operational commands for industrial drives and Programmable Logic Controllers (PLCs). They are created and managed exclusively using WEG Drives Programming Software.
The biggest disadvantage of the .GFB format is its heavily locked, proprietary nature. These files cannot be opened natively by Windows, macOS, or any standard web browser. Sharing logic blocks with non-engineers or project managers is frustrating because it requires installing specialized industrial software. Users frequently need to convert .GFB files into readable formats like PDF for documentation, or TXT and XML for code review.
Because this file format is proprietary and undocumented, standard online converters completely fail to process it. Usually, only the original WEG software can properly read or export the structured data. However, convert.guru offers a practical workaround. Just drag and drop your file to identify the format, view it, and convert it when possible. Even if full compilation isn't supported, our system can inspect the raw file, expose underlying text or hex data, and help you recover readable strings from the block.
In rare cases, a .GFB file might also be a legacy GIFBlast Compressed Image File, an obsolete format used to shrink GIF images for slower internet connections.
Convert.Guru analyzes your GFB file, detects the exact format, and lets you read the text inside.
Users also converted KGP files.
If you want to convert GFB file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use WEG Programming Software or similar software from the "Industrial Automation Logic Storage" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to GFB, try WEG Programming Software or another comparable tool in the "Industrial Automation Logic 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 GFB converter.
