Extract text from HMI screen graphics (BG)
To convert BG screen graphics to another format, you need Kinco HMIware or other Data software.
To convert other file formats to the "HMI & Game Resource" file type, you need software like Kinco HMIware or a similar tool.
The .bg file extension is heavily fragmented, primarily functioning as an HMI (Human-Machine Interface) screen graphic file formatted as raw XML. It is used extensively by industrial touch panel software like Kinco HMIware and Wecon HMI Designer to define user interface layouts. Additionally, game developers frequently rely on the .bg extension to obfuscate background images in visual novels and 3D games (such as Ren'Py or NCSoft Blade & Soul), while other applications use it to store archived webpages (MHTML) or encrypted steganography images.
Because the .bg format has no single standardization, users encounter massive difficulties when attempting to open or edit these files natively. Operating systems cannot associate the extension with a single default program, and opening them often requires expensive, proprietary industrial software or specific game engines. The formats are intentionally obfuscated to lock users out of extracting assets or reverse-engineering HMI layouts.
Converting .bg files to accessible target formats like XML, PNG, JPG, or HTML is essential for data recovery and asset extraction. However, standard online image converters completely fail when processing these files because they cannot parse the conflicting underlying structures (XML, MHTML, ZIP, JPG) tied to this exact same extension.
This is where smart analysis is required. Our tool will inspect the file signature, expose the internal data, and convert it when a supported embedded format is detected.
Convert.Guru analyzes your BG file, detects the exact format, and lets you read the text inside.
Users also converted PNG, JPG, PDF, TST, FMF, EBK and BLACK files.
If you want to convert BG file to BLACK, PNG, JPG, CSV, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use Kinco HMIware or similar software from the "HMI Screen Graphic 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 BG, try Kinco HMIware or another comparable tool in the "HMI Screen Graphic 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 BG converter.
