免费在线 G4 转 PCD 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 was developed by Kodak in order to store images on optical or other media. It is used as a format for archiving scanned documents on Kodak devices. It encodes images in 24-bit color and supports resolutions of up to 6144x4096 pixels.
