About SGS files
The .SGS file format is most commonly a proprietary game save file utilized by the YU-RIS Game Engine, a popular framework for developing Japanese visual novels. These files store critical player data, including story progression, unlocked CGs, and system settings. Additionally, the .SGS extension is used for construction cost estimation files by SAEHAN Information System, and as save data for games like Sins of a Solar Empire. The main disadvantage of the .SGS format is its strictly closed, proprietary nature. These files are not supported by web browsers, require the exact original software to open, and consist of unreadable binary data. Attempting to open an .SGS file in a standard text editor will result in garbled text. Because these files contain highly specific game or application states rather than standard media, traditional conversion to formats like PDF or JPG is usually impossible and meaningless. Standard online converters fail to process them entirely. While direct conversion is rarely applicable, our analysis detects the underlying file signature, helping you figure out exactly which software created it.
Convert.Guru analyzes your SGS file, detects the exact format, and lets you read the text inside.

The SGS 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 SGS converter.
