What is G4 ?

The G4 file format is primarily associated with Group 4 compression, a method used to encode bi-tonal images, typically for fax transmission.

Why Convert G4 to JPG file?

G4 is a black-and-white image format based on Group 4 fax compression, used for scanned documents and faxes, which ordinary image programs rarely open directly. Converting G4 to JPG turns a scanned page or fax image into a standard photo that opens on any device, so you can view, share, or use it like a normal picture.

JPG is compact and universally compatible, ideal for viewing or sharing a scanned document image. Because G4 is black and white, the result is a monochrome picture. For crisp text scans, a lossless format like PNG can look cleaner, but for easy, widely compatible viewing and small file size, JPG brings a G4 fax image into everyday use.
