CBZ to CG4 Conversion: FAQ

What are CBZ files?

A .CBZ file is like a digital comic book where all the pages are neatly packed into one ZIP file. It's the more universal cousin of .CBR files - since ZIP is supported everywhere, you can open CBZ comics on practically any device without special software. Just like flipping through a physical comic, reader apps display the pages in perfect order (thanks to numbered filenames). These files are perfect for collectors and readers who want their entire comic collection organized in a single, space-saving file that won't lose image quality.

What are CG4 files?

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data.
