Free Online RGBA to G4 Converter

The RGBA extension identifies files commonly known as Raw red, green, blue, and alpha samples. It contains low-level pixel or channel data whose dimensions and sample layout may need to be supplied separately. Imaging and video tools use the expected color model and geometry to display, process, or convert the raw picture.

The G4 extension identifies files commonly known as Group 4 FAX. It represents bi-level image data optimized for fax transmission and document scanning. Compatible imaging or document software can decode the compressed page, display it, and convert it to a more widely supported raster format.
