G3 to PDF Conversion: FAQ

What are G3 files?

A G3 file most likely contains the digital image of a document that was either sent or received by fax. Such files use a type of compression called "Group 3", meant to efficiently minimise file size by compressing the white space which generally predominates in faxed documents. G3 files were mostly used during the fax machine era and are currently considered rare and obsolete.

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics. As opposed to other formats with a similar function, PDFs can be easily transferred between different applications and different operating systems, and generally don't have a very large size. Moreover, they can offer decent image quality in a compressed format and can be secured with passwords or watermarks.
