Convert CBZ/CBR/Dir into Epub for e-reader devices (Kindle Devices, ...)

My goal is to make a simple, crossplatform, and fast tool to convert comics into epub.

Epub is now support by Amazon through SendToKindle, by Email or by using the App. So I've made it simple to support the size limit constraint of those services.

Installation

First ensure to have a working version of GO: Installation

Then install the last version of the tool:

go install github.com/celogeek/go-comic-converter@latest

To force install a specific version:

go install github.com/celogeek/go-comic-converter@TAG
# Ex: go install github.com/celogeek/go-comic-converter@v1.0.0

Add GOPATH to your PATH

export PATH=$(go env GOPATH)/bin:$PATH

Supported image files

The supported image files are jpeg and png from the sources.

The extensions can be: jpg, jpeg, png.

The case for extensions doesn't matter.

Usage

Convert directory

Convert every supported image files found in the input directory:

go-comic-converter --profile KS --input ~/Download/MyComic

By default it will output: ~/Download/MyComic.epub

Convert CBZ, ZIP, CBR, RAR, PDF

Convert every supported image files found in the input directory:

go-comic-converter --profile KS --input ~/Download/MyComic.[CBZ,ZIP,CBR,RAR,PDF]

By default it will output: ~/Download/MyComic.epub

Convert with size limit

If you send your ePub through Amazon service, you have some size limitation:

• Email : 50Mb (including encoding, so 40Mb for RAW file)
• App : 50Mb
• Website: 200Mb

You can split your file using the "--limitmb MB" option:

go-comic-converter --profile KS --input ~/Download/MyComic.[CBZ,ZIP,CBR,RAR,PDF] --limitmb 200

If you have more than 1 file the output will be:

• ~/Download/MyComic PART_01.epub
• ~/Download/MyComic PART_02.epub
• ...

The ePub include as a first page:

• Title
• Part NUM / TOTAL
