無料オンラインCDRからG4へのコンバーター

This is a format for storing graphical information, created in the CorelDRAW program. It can contain raster and vector images. It’s used exclusively in vector editors from the Corel company. For use in third-party software it’s necessary to use converters. Version 10 and earlier can be opened in vector software from Adobe. CDR can be opened also with the help of Inkscape and sK1 programs.

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).
