Comic readers and ebook libraries commonly use CBR files to keep comic pages together as one book. To make one from PNG scans or artwork, package the images in page order in a RAR archive and use the .cbr extension.
What the PNG format is
PNG is a lossless raster image format that supports transparency. Screenshots, scanned pages, and digital artwork are often saved as PNG by image editors and drawing programs, including GIMP, Krita, and Photoshop. Each PNG stores one image; it does not contain a book’s page sequence.
What the CBR format is
CBR is a convention for comic books stored as RAR archives. The archive contains page images, commonly PNG or JPEG, that compatible comic readers display in sequence. It keeps a set of pages in one file, but it does not combine them into a new image format or improve their image quality.
How to convert PNG to CBR
Online on 101convert.com

- Choose CBR as the output format and start the conversion.
- Download the resulting CBR file.
Offline with desktop software
There is no standard free, open-source utility that creates genuine RAR archives for CBR. The RAR command-line utility can create one on Windows, macOS, or Linux. First, rename pages with zero-padded numbers so they sort correctly, such as page001.png and page002.png. In a terminal opened in the image folder, run:
rar a book.cbr page*.png
On Windows, WinRAR provides a graphical option: select the page images, choose Add to archive..., enter book.cbr as the archive name, and create the archive using RAR format.
Quality and compatibility
Archiving does not recompress or alter the PNG image data, so the pages retain their original image quality. Page order depends on filenames; use consistent zero-padded numbering to avoid sequences such as page 10 appearing before page 2. CBR support and supported RAR archive versions vary between comic readers, so test the file in the reader that will be used.
