The Texture class in the Unity engine uses this imported version, and Unity uploads it to the GPU for real-time display. Instead, when you import the texture, Unity creates a new representation of the image in a different format which is stored in the Project’s Library folder.
png image file as a texture, it does not use the original. The conversion process is required because most file formats are optimized to save storage space, whereas in a game or a real-time application, the asset data needs to be in a format that is ready for hardware, such as the CPU, graphics, or audio hardware, to use immediately. It stores these converted files, and the data associated with them, in the Asset Database.
With most types of asset, Unity needs to convert the data from the asset’s source file into a format that it can use in a game or real-time application.
