An interesting open-source tool with a very specific use case.

**CBconvert** is **a comic book converter** that can convert comics into different formats to fit all sorts of devices.

For me, personally, this will be a first, since I have never tried a converter like this before. Here, I explore and highlight what this tool has to offer.

🚧

The app is fairly new and is in active development. Expect things to change.

## CBconvert: Overview ⭐

Written primarily in the [Go](https://go.dev/?ref=itsfoss.com) programming language, CBconvert aims to act as a one-stop app for all your comic book conversion needs.

It can read the most commonly used file formats, such as **CBR** (RAR), XPS, **CB7** (7Z), **CBT** (TAR), **PDF**, and more.

You can convert those files into two distinct formats, **CBZ** (ZIP) and **CBT** (TAR).

Don't think that CBconvert's only purpose is to convert comic books, you can also use it to make some visual tweaks. I'll talk about that in a second.

**Key Features:**

- **Useful editing tools**
- **Comic book conversion**
- **Extract cover images from comics**

Without any further ado, let's dive into CBconvert.

## Initial Impressions 👨‍💻

While the converter can run on **Linux, Windows, and macOS**, I tried it on a Linux system.

I started by adding a few comics (available in the public domain) to the app by using the 'Add Files' option in the sidebar menu. I was able to add multiple comics, without many issues.

Likewise, I then moved on to take a look at the various function tabs.

The **first tab called 'Input'** housed a few options, such as to **set the minimum size limit**, **opting for only grayscale images**, and more. I didn't need to use those, but the options are certainly useful if you want to add prerequisites to the files you wish to convert.

The **second tab is where you can do the conversion of comics**, it is called 'Output'. I set the output directory, and selected the 'ZIP' archive format for getting a **.cbz file output**.

It also had the option to add a suffix to the output file, and to remove any non-image files from the archive, as shown below.

After all the output settings were set, I clicked on '**Convert'**. It then started to process all the comics one by one. The operation was quick, with the desired end-results.

You're maybe wondering; *why does this cover look different from the one before?* 

Well, before converting these comics, I took the liberty of trying my hand at tweaking the visuals of the comic books.

Thanks to the '**Transform**' tab that allowed me to play around with various settings such as the **brightness**, **contrast**, **input/output levels**, and more.

I would say that **this feature needs more polishing**, as the changes were not being reflected in real-time for a preview, it took some time for the changes to appear.

📋

Do keep in mind that I didn't have to select the other comics, all of them received the same tweaks, alongside the 'Daredevil' one.

Then, **there's a third tab called 'Image'**, it allowed me to export the cover photo in various image formats such as JPEG, PNG, TIFF, WebP and more.

CBconvert also features some options to **create a thumbnail from the cover pic**, **tweak the image quality**, **make it into grayscale**, and even **apply some resizing filters** to it.
