免费在线 G4 转 YUV 转换器

G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).

This format is used to store images that have been divided into Y, U, and V color components. In this case, Y corresponds to brightness, and the variables U and V correspond to color information. This format is able to store more accurate color information than the RGB color space. The YUV Color System also allows you to store video files and save a particular sequence of images.
