About IGF files

An .igf file is a proprietary data container primarily used to store lighting photometric data or HVAC data logger graphs. In the lighting industry, these files are generated as test reports by LISUN Group testing hardware and are frequently analyzed using DIALux evo. In the building management sector, Infratrend Systems uses the .igf format to store HVAC data logger graphs for TrendXpert software. The main disadvantage of the .igf format is its strict vendor lock-in. You cannot open these files natively on any operating system, and sharing them requires the recipient to have expensive, niche engineering software installed. They are entirely unsuited for web viewing or general archiving. To make this data useful, you must convert it. For lighting interoperability, convert .igf to standard IES or LDT files. To extract HVAC log data, convert to CSV or XLSX. For easy sharing and reporting, convert to PDF. Drag and drop your file here to analyze and convert it securely right in your browser.

Convert.Guru analyzes your IGF file, detects the exact format, and lets you read the text inside.

The IGF 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 IGF converter.
