G3 to WEBP Conversion: FAQ

What are G3 files?

The .g3 file extension is most commonly associated with Group 3 Fax images, a digital format developed by the CCITT (now ITU-T) to transmit black-and-white documents efficiently over analog telephone lines. By utilizing basic run-length encoding compression, this format minimizes file sizes for text and line drawings while maintaining legibility across vintage fax machines and early digital archiving systems.

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
