How to Install Flameshot Screenshot Tool in Linux

Flameshot is an open-source screenshot tool available for Linux, Mac, and Windows. It is created with C++ and QT5 language. Every popular Linux distribution comes with a screenshot tool but they lack few functionalities that flameshot offers.

Some of the popular features include.

  • Supports graphical and CLI mode.
  • Edit images instantly.
  • Image uploads to Imgur.
  • Export and import configuration.
  • Easy to use and customizable.

In this article, you will learn how to install and use Flameshot screenshot software in Linux desktop systems. For the purpose of demonstration, I am using Linux Mint 20.04.

How to Install Flameshot in Linux

Flameshot can be installed using package managers. Before installing through this method make sure you verify the version that ships with your OS.

$ sudo dnf install flameshot  # Rhel, Centos, Fedora
$ sudo apt install flameshot  # Debian, Ubuntu-based distro 

The second method would be to download the flameshot package (.rpm or .deb) from GitHub based upon your distribution and install it locally. This is the method I prefer since I can install the new version irrespective of what ships with my distribution.

# Ubuntu based distribution
$ wget
$ dpkg -i flameshot-0.9.0-1.ubuntu-20.04.amd64.deb

# Rhel based distribution
$ wget
$ rpm -i flameshot-0.9.0-1.fc32.x86_64.rpm

You can also install the most latest version of Flameshot from the snap store or flathub.

How to Use Flameshot in Linux Desktop

Flameshot can be started manually or we can make it auto start when the system boots up. Go to “Menu → Type flameshot → Selectflameshot” will be launched and on the system tray. To access from the system tray make sure you have a systray installed in your OS. Since I am running Linux Mint, by default it has a system tray.
