JPEG typically achieves 10:1 compression with little perceptible loss in image quality.Ĭomic book archive files mainly consist of a series of image files, typically PNG (lossless compression) or JPEG (lossy compression) files, stored as a single archive file. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The idea was made popular by the CDisplay sequential image viewer since then, many viewers for different platforms have been created. A comic book archive or comic book reader file (also called sequential image file) is a type of archive file for the purpose of sequential viewing of images, commonly for comic books.
