flameshot Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. flameshot-0.6.0.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

Example commands:

  • capture with GUI:

    flameshot gui

  • capture with GUI with custom save path:

    flameshot gui -p ~/myStuff/captures

  • open GUI with a delay of 2 seconds:

    flameshot gui -d 2000

  • fullscreen capture with custom save path (no GUI) and delayed:

    flameshot full -p ~/myStuff/captures -d 5000

  • fullscreen capture with custom save path copying to clipboard:

    flameshot full -c -p ~/myStuff/captures

  • capture the screen containing the mouse and print the image (bytes) in PNG format:

    flameshot screen -r

  • capture the screen number 1 and copy it to the clipboard:

    flameshot screen -n 1 -c

In case of doubt choose the first or the second command as shortcut in your favorite desktop environment.

A systray icon will be in your system's panel while Flameshot is running. Do a right click on the tray icon and you'll see some menu items to open the configuration window and the information window. Check out the information window to see all the available shortcuts in the graphical capture mode.

CLI configuration

You can use the graphical menu to configure Flameshot, but alternatively you can use your terminal or scripts to do so.

  • open the configuration menu:

    flameshot config

  • show the initial help message in the capture mode:

    flameshot config --showhelp true

  • for more information about the available options use the help flag:

    flameshot config -h

Keyboard shortcuts


These shortcuts are available in GUI mode:

Keys Description
, , , Move selection 1px
Shift + , , , Resize selection 1px
Esc Quit capture
Ctrl + C Copy to clipboard
Ctrl + S Save selection as a file
Ctrl + Z Undo the last modification
Right Click Show color picker
Mouse Wheel Change the tool's thickness

Shift + drag a handler of the selection area: mirror redimension in the opposite handler.


If you want use Flameshot as a default screenshot utility, chances are you want to launch it using the Prt Sc key. Flameshot doesn't yet offer a fully-automated option to do so, but you can configure your system to do so.

On KDE Plasma desktop

To make configuration easier, there's a file in the repository that more or less automates this process. This file will assign the following keys to the following actions by default:

Keys Description
Prt Sc Start the Flameshot screenshot tool and take a screenshot
Ctrl + Prt Sc Wait for 3 seconds, then start the Flameshot screenshot tool and take a screenshot
Shift + Prt Sc Take a full-screen (all monitors) screenshot and save it
Ctrl + Shift + Prt Sc Take a full-screen (all monitors) screenshot and copy it to the clipboard

If you don't like the defaults, you can change them manually later.

Steps for using the configuration:

  1. The configuration file configures shortcuts so that Flameshot automatically saves (without opening the save dialog) screenshots to ~/Pictures/Screenshots folder. Make sure you have that folder by running the following command:

    mkdir -p ~/Pictures/Screenshots

    (If you don't like the default location, you can skip this step and configure your preferred directory later.)

  2. Download the configuration file:

    cd ~/Desktop; wget https://raw.githubusercontent.com/lupoDharkael/flameshot/master/docs/shortcuts-config/flameshot-shortcuts-kde
  3. Go to System SettingsShortcutsCustom Shortcuts.

  4. If there's one, you'll need to disable an entry for Spectacle, the default KDE screenshot utility first because its shortcuts might collide with Flameshot's ones; so, just uncheck the Spectacle entry.

  5. Click EditImport..., navigate to the Desktop folder (or wherever you saved the configuration file) and open the configuration file.

  6. Now the Flameshot entry should appear in the list. Click Apply to apply the changes.

  7. If you want to change the defaults, you can expand the entry, select the appropriate action and modify it as you wish; the process is pretty mush self-explanatory.


  • Experimental Gnome Wayland and Plasma Wayland support.

  • If you are using Gnome you need to install the TopIcons extension in order to see the systemtray icon.

  • In order to speed up the first launch of Flameshot (DBus init of the app can be slow), consider starting the application automatically on boot.

  • Press Enter or Ctrl + C when you are in a capture mode and you don't have an active selection and the whole desktop will be copied to your clipboard! Pressing Ctrl + S will save your capture in a file! Check the Shortcuts for more information.

  • Execute the command flameshot without parameters or use the "Launch Flameshot" desktop entry to launch a running instance of the program without taking actions.


There are packages available for a few distros:


The compilation requires Qt version 5.3 or higher and GCC 4.9.2 or higher.


Compilation Dependencies:

apt install git g++ build-essential qt5-qmake qt5-default qttools5-dev-tools libqt5svg5-dev

Compilation: run qmake && make in the main directory.


Compilation Dependencies:

dnf install qt5-devel gcc-c++ git qt5-qtbase-devel qt5-linguist qt5-qtsvg-devel

Compilation: run qmake-qt5 && make in the main directory.


Compilation Dependencies:

pacman -S base-devel git qt5-base qt5-tools qt5-svg

Compilation: run qmake && make in the main directory.


Simply use make install with privileges.


Having git installed is required if you want to have precise app version information inside Flameshot after the generation of the makefile with qmake.

In order to generate the makefile installing in /usr instead of in /usr/local you can use the packaging option to generate the proper makefile (qmake CONFIG+=packaging instead of just qmake).

If you want to install in a custom directory you can use the INSTALL_ROOT variable.

Example: You want to install Flameshot in ~/myBuilds/test. You would execute the following to do so: qmake CONFIG+=packaging && make INSTALL_ROOT=~/myBuilds/test install

I improve Flameshot in my free time because I want to create something good for everyone to use. If you want you can donate some bucks here.


I really appreciate those who have shown interest in the early development process:
