Extract text from Nokia and Nikon graphics (NGF)
To convert NGF graphics to another format, you need Nikon ViewNX-i or other Raster Image software.
To convert other file formats to the "Mobile & Raw Imaging" file type, you need software like Nikon ViewNX-i or a similar tool.
The .ngf file extension typically represents a legacy raster image format with two primary origins. Most commonly, it serves as a Nokia Graphics File, a proprietary format used to store wallpapers, icons, and UI elements on older Nokia S40 and S60 series mobile handsets. These files are optimized for the low-resolution, monochrome, or limited-color screens of early 2000s devices. Secondarily, the extension is associated with Nikon digital imaging workflows, acting as a raw image container similar to the standard NEF (Nikon Electronic Format). Like other raw formats, the Nikon .ngf stores unprocessed sensor data in a TIFF-based structure, allowing for non-destructive editing of exposure and white balance.
Users typically encounter .ngf files when recovering data from old phone backups or legacy photography archives. The primary problem is the complete lack of native support on modern operating systems; neither Windows File Explorer nor macOS Preview can recognize or render these files. Additionally, Nokia .ngf files often possess non-square pixels or specific aspect ratios that look distorted on modern displays. To make these files usable, users should convert them to standard formats. For preserving the exact pixel data of Nokia icons, convert to PNG. For archiving high-quality Nikon raw data, convert to TIFF or PDF. For general viewing and sharing, JPG is the most compatible target.
Convert.Guru analyzes your NGF file, detects the exact format, and lets you read the text inside.
If you want to convert NGF file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Nikon ViewNX-i or similar software from the "Legacy Mobile Graphics" 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 NGF, try Nikon ViewNX-i or another comparable tool in the "Legacy Mobile Graphics" 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 NGF converter.
