Description
The NGG file format, standing for Nokia Group Graphics, is a proprietary image format used primarily by some Nokia mobile phones. It is designed specifically for the storage and display of graphics on Nokia devices, optimizing for their screen sizes and color limitations. NGG files are typically used for wallpapers, icons, and other graphical elements within the phone's user interface. Due to its specialized nature, the NGG format is not widely supported outside of Nokia's ecosystem and requires specific software or conversions to be viewed on non-Nokia devices.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
