Screenshot from 2023-11-26 12-43-32


Requirements depend on your platform.

Prebuilt binaries are available here - https://github.com/qarmin/czkawka/releases/


Prebuild binaries

Ubuntu - sudo apt install libgtk-4 libheif libraw ffmpeg -y

Snap -

none - all needed libraries are bundled in snap except ffmpeg - https://snapcraft.io/czkawka


none - all needed libraries are bundled - https://flathub.org/apps/com.github.qarmin.czkawka


/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install gtk4 adwaita-icon-theme ffmpeg librsvg libheif libraw


All needed libraries should be bundled in zip (except ffmpeg which you need download and unpack to location with czkawka_gui.exe - https://ffmpeg.org/download.html#build-windows)

You can also install the app via msys2 (webp and heif should work here) - https://www.msys2.org/#installation (czkawka package - https://packages.msys2.org/base/mingw-w64-czkawka)

pacman -S mingw-w64-x86_64-czkawka-gui

and you can create a shortcut to C:\msys64\mingw64\bin\czkawka_gui.exe


Compiling the gui is harder than compiling cli or core, because it uses gtk4 which is written in C and also requires a lot build and runtime dependencies.


Program Minimal version
Rust 1.74.0
GTK 4.6

Linux (Ubuntu, but on other OS should work similar)

sudo apt install libgtk-4-dev libheif-dev libraw-dev -y
cargo run --release --bin czkawka_gui
# Or with support for heif and libraw
cargo run --release --bin czkawka_gui --features "heif,libraw"


/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install rustup gtk4 adwaita-icon-theme ffmpeg librsvg libheif libraw pkg-config
cargo run --release --bin czkawka_gui
# Or with support for heif and libraw
cargo run --release --bin czkawka_gui --features "heif,libraw"


Currently, there is are no instructions on how to compile the app on Windows natively.
You can check for CI for instructions how to cross-compile the app from linux to windows (uses prebuilt docker image) - CI Instructions
There exists a mingw recipe which you can try to convert for your purposes - https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-czkawka/PKGBUILD


Not all available features and/or components implemented here, this is the list of limitations:

  • Snap versions does not allow to use the similar videos feature
  • Windows version does not support heif and webp files with prebuilt binaries
  • Prebuilt binaries for mac arm do not exist
  • On Windows, text may appear very small on high resolution displays, a solution is to manually change DPI scaling for this app, see :

Czkawka is a Polish word which means hiccup.

I chose this name because I wanted to hear people speaking other languages pronounce it, so feel free to spell it the way you want.

This name is not as bad as it seems, because I was also thinking about using words like żółć, gżegżółka or żołądź, but I gave up on these ideas because they contained Polish characters, which would cause difficulty in searching for the project.

At the beginning of the program creation, if the response concerning the name was unanimously negative, I prepared myself for a possible change of the name of the program, and the opinions were extremely mixed.
