About G3 (.G3)
The G3 file extension is primarily associated with Group 3 fax images, which are monochrome bitmap files used in fax machines. These files store scanned documents in a compressed format, making them efficient for transmission over phone lines. Interestingly, Group 3 fax standards were established in the 1980s to improve fax communication speed and reliability.
Technical Details
Technically, G3 files use a run-length encoding compression method defined by the CCITT T.4 standard, designed to compress black-and-white images efficiently. The format is single-bit, meaning each pixel is either black or white, suitable for text and simple graphics. Its design enables fax machines to transmit data at speeds up to 14.4 kbps, a significant improvement over earlier fax technologies.
Additional Information & Use Cases
G3 files are commonly utilized in office environments where faxed documents need to be digitally archived or shared. The format supports CCITT Group 3 compression, which balances file size reduction with image quality. Many modern scanners and fax software can open or convert G3 files to more common image formats like TIFF or PDF.
