Changing the file extension and resolution of multiple images at once is easy on Linux, thanks to Converseen, a GUI batch image processing tool.

Converting or resizing images on Linux is easy: you pick an image editor that suits your needs and follow a series of steps on it to perform these operations. However, the problem arises when your image editor doesn't support batch operation, which is the case with many image manipulation software.

But thankfully, there are tools like Converseen, which make it much easier to perform batch manipulation on images in Linux than it seems.

Let's dive in to check out Converseen and see how you can use it to batch resize and convert images on Linux.

Converseen is an open-source GUI software for batch image conversion and resizing. It uses ImageMagick at its core—a popular CLI-based utility for image manipulation that supports over 100 image file formats like JPEG, JPEG-2000, PNG, SVG, DPX, EXR, and many others—to facilitate batch image manipulation.

With Converseen, you can convert, resize, flip, and rotate one or multiple images at once. Additionally, you can also compress images to reduce their size, should you need to share them online.

The following is a list of all the Converseen features available on Linux:

Converseen is available on most major Linux distros. Here's how to get it on your machine.

If you're using Debian or Ubuntu, open the terminal and run the following command to install Converseen:

On Fedora, CentOS, or Red Hat Enterprise Linux (RHEL), use:

Arch Linux or Manjaro users can install Converseen with:

In case you're using any other Linux distro on your computer, you can install Converseen via Flatpak. For this, first, make sure your system has Flatpak support. To do this, open the terminal and run:

If this returns a version number, Flatpak is present on your system, and you can proceed with Converseen installation. Else, check out our Flatpak guide to install it on your system first.

Once you've installed Flatpak, run the command below to install Converseen:

Once you've installed Converseen on your Linux machine, you're ready to use it.

Open the Applications menu, search for Converseen, and launch it. Converseen will greet you with its home screen, which has a bunch of menus and options.

As you can see, this window is divided into two sections: on the left hand, you have the Actions Panel, from where you can pick an action to perform on the image(s), and to its right, there's a file selector window that lets you set image properties based on the operation you select from the left pane.

In addition, there's also a toolbar in Converseen. It's located at the top and includes options like Open images, Add images, Convert, Remove images, Remove all, Check, and Check all.

One of the key features of Converseen is the ability to bulk convert images at once. So if you've got a bunch of images in, say, the PNG format that you wish to convert to JPG, you simply need to pick the appropriate output format, and Converseen will convert them instantly.

Here are the steps you need to follow to do this:

Once the conversion is complete, click on the Open destination button in the Status window, and Converseen will open the directory where it saved the converted images.

Much like batch image conversion, Converseen also works well for bulk image resizing. Follow these steps to learn how to bulk resize images on Linux using Converseen:

After Converseen finishes resizing your images, tap on the Open destination button to access the resized images.

Converseen is a really handy tool that simplifies bulk image resizing and conversion needs on Linux. It has a simple interface and is pretty easy to use as well, so you can easily convert multiple images between different formats or resize them effectively, all while keeping their overall quality intact.

Of course, image conversion and resizing are just two use-cases of Converseen, and you can use the software for rotating and flipping images, compressing them, and changing their resolution.

Alternatively, if you just want to rename multiple images at once, there are a few other ways to effectively batch rename files on your Linux machine.
