Looking for app to convert your photo images into other formats? Try Switcheroo.

For batch image processing, I’d recommend to use Converseen. However, stupid simple applications are always good choices for beginners.

And, Switcheroo is one stupid simple app for converting photo images, while having modern look and feel in today’s Linux desktop.

Click ‘Open Images’ or drag’n’drop files into app window

With it, just click “Open Images” button and choose your image file/files, or drag and drop files into the app window to open them.

It shows thumbnail preview of all opened images, along with delete buttons in top-right for each images.

By using top-left ‘+’ button, user can add more images (Tips: hold Ctrl or Shift can select multiple files). And, ‘≡’ menu even provides an option to paste images from clipboard.

After opening all your photo images, click the drop-down box in the right of “Export Format” to select which file format to convert to.

At the moment of writing, it support converting image to PNG, JPG, WEBP, HEIF, HEIC, BMP, AVIF, JXL, TIFF, PDF, GIF. Though, you have to either use top-right hamburger menu or press Ctrl + H to show less popular file types.

The app’s hamburger menu

Before clicking ‘Convert’, it provides few more options, such as set background color, resize with or without aspect ratio, and change image quality. There’s also “Save To Zip” to directly output images into ZIP archive.

Instead of providing an in-app option, it pops-up file chooser dialog asks to choose where to save output images or ZIP archive, once clicking “Convert” button.

How to Install Switcheroo Image Converter

The app is available as universal Flatpak package, that can be installed in Ubuntu, Debian, Fedora, Arch, Chrome OS, and most other Linux, even including the mobile device, such as PinePhone.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the Flatpak daemon:

sudo apt install flatpak

Other Linux can follow the official setup guide to get Flatpak support.

2. Then, run command to install the app as flatpak:

flatpak install https://dl.flathub.org/repo/appstream/io.gitlab.adhami3310.Converter.flatpakref

As you see in the screenshot, the downside is that a small app can have 1 GB downloading due to run-time libraries (though shared).

3. Once installed, search for and launch it from your system application launcher, start menu, or ‘Activities’ overview depends on desktop environment.

First time installing Flatpak app needs a log out and back in, to make app icon visible.

4. To enable drag’n’drop support, you need to grant access permission to the folders that contain the photo images.
To do so, install Flatseal, then use it to allow access either all user files or certain folders (by adding Other files).

Uninstall Switcheroo

To uninstall the image converting application, also open terminal (Ctrl+Alt+T), then run command:

flatpak uninstall --delete-data io.gitlab.adhami3310.Converter

Also run flatpak uninstall --unused to remove useless run-time libraries.

How to Install Shotwell 0.32.3 in Ubuntu

Shotwell is available to install in Ubuntu via a few different ways.

Snap package

Canonical (the company behind Ubuntu) maintains Shotwell as Snap package, which runs in sandbox. However, it’s stuck at 0.32.1 at the moment of writing.

The snap package is available to install in Ubuntu Software (or App Center for 23.10).

Flatpak package

Shotwell is also available to install as Flatpak package, another universal Linux package format runs in sandbox. It’s marked as maintained by the Shotwell developers, but NOT verified.

The Flatpak is at version of 0.32.2 at the moment of writing (check HERE). Ubuntu user can press Ctrl+Alt+T on keyboard to open terminal, and run 2 commands one by one to install it:

  • First, make sure the flatpak daemon is installed:
    sudo apt install flatpak
  • Then, install shotwell as flatpak:
    flatpak install https://dl.flathub.org/repo/appstream/org.gnome.Shotwell.flatpakref

Ubuntu PPA

For those who prefer the classic native .deb package format, I’ve upload the package into this unofficial PPA for Ubuntu 22.04, 23.04, and 23.10.

1. First, search for and open terminal from your system application menu, or press Ctrl+Alt+T on keyboard. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/shotwell

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Next, launch Software Updater (Update Manager), then install the updates for the software package.

Or, run command in terminal to install/upgrade the Shotwell package:

sudo apt install shotwell

NOTE: Linux Mint user may need to run sudo apt update first to refresh package cache.

Finally, either right-click on your photo images to select open with the photo manager, or search for and launch shotwell from ‘Activities’ overview and enjoy!

Uninstall Shotwell 0.32.3

For any issue, it’s recommended to purge the Ubuntu PPA. Which, will remove PPA and downgrade shotwell to the pre-installed version.

To do so, open terminal (Ctrl+Alt+T) and run command:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/shotwell

For the Snap package, just remove it from Ubuntu Software or App Center. While, Flatpak package can be removed by running the command below in a terminal window:

flatpak uninstall --delete-data org.gnome.Shotwell

How to Install digiKam 8.0.0 in Ubuntu & other Linux

The new digiKam release is available to install via both Flatpak and AppImage. Choose either one that you prefer.

Option 1: digiKam Flatpak

1. For digiKam Flatpak package, first press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to enable Flatpak support.

sudo apt install flatpak

2. Then, run command to install digiKam as flatpak package:

flatpak install https://dl.flathub.org/repo/appstream/org.kde.digikam.flatpakref

As you see in the screenshot below, the flatpak package however will do many downloads for the run-time libraries.

Option 2: digiKam AppImage

Some users do NOT like Flatpak, because it take much more disk spaces. In the case, you can choose to use the non-install AppImage package.

1.) First, select download the AppImage package from the link below:

2.) Then, open the Downloads folder in your file manager. And, do following steps to launch digiKam:

  1. Right-click on the AppImage package, and click open “Properties”.
  2. Navigate to “Permissions” tab, and enable “Allow executing file as program”.
  3. Close the “Properties” dialog.
  4. Finally, right-click on AppImage, and click “Run” to launch digiKam.

Create shortcut for the digiKam AppImage

Click run the AppImage launches the digiKam software directly. If you want to add a shortcut into app launcher (search results in ‘Show Applications’ and/or ‘Activities’ overview), do following steps one by one.

1. First, it’s recommended to put the AppImage package into a certain folder for long time use. Here I chose the “.local/bin” directory.

Just, press Ctrl+H in Files, and navigate to .local -> bin (create bin folder if not exist). Then, copy or move the digiKam AppImage into this folder.

2. Then, download the logo icon from web. Just, go to its website, right-click on the logo in top-left and select “Save image as” to download the file.

Finally, rename the file to digikam.svg, and store in “.local/share/icons” (also, create the ‘icons’ sub-folder if not exist).

3. Finally, open terminal (Ctrl+Alt+T) and run command to create the shortcut config file:

gedit ~/.local/share/applications/org.kde.digikam.desktop

Replace gedit with gnome-text-editor for Ubuntu 22.10+, or use nano instead.

When file opens in text editor (or terminal for nano), paste follow lines and save it. For nano, press Ctrl+X, type y and hit Enter to save file.

[Desktop Entry]
Name=digiKam
Comment=digiKam photo management tool
Exec=digiKam-8.0.0-x86-64.appimage
Icon=digikam
Categories=Graphics;
Type=Application
Terminal=false

NOTE: if the bin folder under .local was previously not exist. You need to log out and back in to make it in your PATH.

4. After that, you should be able to search for and launch digiKam from app launcher.

That’s all. Enjoy!

Darktable, the free open-source photography application and raw developer, released version 4.2.1 a few days ago. Here’s how to install it in Ubuntu 20.04, Ubuntu 22.04 and Ubuntu 22.10.

Darktable 4.2.1 is a new point release. There’s no big features but minor changes. It now uses magic bytes to identify JPEG files, so even JPEG image with incorrect file extension is supported. Also, it adds ability to assign shortcuts to the “quick access” style and preset menus at the bottom of the darkroom view.

The release also added base support for Canon EOS Kiss X10/X10i, Leica M9 (dng), Nikon Z 30 (12bit-compressed, 14bit-compressed), OM System OM-1/OM-5, Panasonic DC-G95D/DC-G99D (4:3), Ricoh GR IIIx (dng).

It also adds White Balance Presets for Nikon Z 9, and noise profiles for Fujifilm GFX100S, Fujifilm X-H2/X-H2S, OM System OM-1, Sony ILCE-7SM3, Canon EOS 250D / Kiss X10 / Rebel SL3 / 200D Mark II, Canon EOS R7.

For more about Darktable 4.2.1, see the release note in github.

How to install Darktable 4.2.1 in Ubuntu via PPA

The software website refers to the OBS repository that contains native packages for Ubuntu, Debian, Fedora and SUSE.

For choice, here’s an unofficial Ubuntu PPA contains the packages for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10.

NOTE: There’s no JPEG-XL support, since the library is not available in Ubuntu repository until 23.04. And, the new release requires libheif >= 1.13.0, so HEIF support excluded in Ubuntu 22.04 and earlier. Please leave comment if you do need them.

1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/darktable

2. Linux Mint use may need to run command to manually refresh package cache:

sudo apt update

3. Finally install the photography software either via the command below:

sudo apt install darktable

Or by installing package updates via Software Updater. NOTE: You are strongly advised to take a backup first.

Darktable is also available as universal Flatpak package that works in most Linux systems.

Fix no window border issue

Darktable seems not rendering its window border in Ubuntu with default Wayland session. As a workaround, either switch back to classic Xorg session, or run Darktable using X11 backend.

To do so, either open terminal (Ctrl+Alt+T) and run command to launch Darktable from command line:

GDK_BACKEND=x11 darktable

Or, modify the shortcut icon file via following steps:

1. Open terminal (Ctrl+Alt+T) and copy the shortcut file to local folder by running command:

sudo cp /usr/share/applications/org.darktable.darktable.desktop ~/.local/share/applications

2. Change the owner ship to current user:

sudo chown $USER:$USER ~/.local/share/applications/org.darktable.darktable.desktop

3. Edit the file with gedit text editor:

gedit ~/.local/share/applications/org.darktable.darktable.desktop

For Ubuntu 22.10 +, replace gedit with gnome-text-editor.

4. Finally, find out the line started with Exec and change it into Exec=env GDK_BACKEND=x11 /usr/bin/darktable %U. Also remove the line start with TryExec.

Uninstall:

To remove darktable, simple run command in a terminal window:

sudo apt remove --autoremove darktable

And, remove the Ubuntu PPA by either removing source line in ‘Software & Updates’ utility under ‘Other Software’ tab, or running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/darktable

If you would like to revert back the stock Darktable package in system repository, just purge the PPA instead of removing it as well as the software packages and install old version back.

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/darktable

Converseen image converter announced 0.9.10.0 release few days ago. Here’s how to install it in Ubuntu via PPA.

Converseen is a free and open-source tool for converting or resizing a large quantity of photo images to another format with a few mouse clicks.

The new 0.9.10.0 release redesigned the Images Settings dialog. Previously, it automatically removes the metadata (information including date & time, device, and even location you capture the photo image) in output images, and replaces with only modified date and other non-sensitive data.

Now, it provides a “Remove image’s metadata” check-box. So, user can manually choose to either to remove the metadata information about the photo images in output files.

As you can see in the screenshot above, it now supports configuring the compression level and image quality for WebP images. As well, it fixes a bug that inhibits the overwrite feature when the Rename option is checked.

How to install the new Converseen 0.9.10.0 in Ubuntu

The image converter is available to install in different package formats: AppImage, Snap, and Deb. Choose either one that you prefer.

1. AppImage

The software website provides the universal AppImage for downloading via the link button below:

It’s a non-install package. Just grab it, right-click and go to ‘Properties’ dialog to add executable permission. Finally, click run the AppImage will launch the tool.

2. Snap

For Ubuntu 20.04+, the snap package is the easiest way to get converseen, though it runs in sandbox. Just open Ubuntu Software, search for and install the package marked as ‘Snap Store (snap)’.

3. Ubuntu PPA (.deb)

For those who prefer the classic .deb package format, there’s unofficial PPA that contains the package for Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 22.10.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

Type user password (no asterisk feedback) and hit Enter to continue.

2. Then, install the software package by running command:

sudo apt install converseen

Linux Mint user may have to run sudo apt update first to update cache.

Uninstall:

The PPA also contains some other software packages, so you may remove it immediately after installed Liferea.

To do so, either run the command below in terminal, or remove the source line under “Other Software” tab in Software & Updates tool.

sudo add-apt-repository --remove ppa:ubuntuhandbook1/apps

To remove the feed reader package, simply run command:

sudo apt remove converseen

That’s all. Enjoy!
