What is it for

Caesium is an image compression software that helps you store, send and share digital pictures, supporting JPG, PNG and WebP formats.
You can quickly reduce the file size (and resolution, if you want) by preserving the overall quality of the image.

Supported Platforms

  • Windows: 10 (build 1809 or later) (use old version v1.x for Windows 7 or 8 - link)
  • MacOS: 10.15+
  • Linux: tested on Ubuntu 22.04 and Manjaro

Note: only 64bit versions are supported

Installation

Head to the releases' page for the available downloads.

  • Windows: installer and portable versions are available
  • MacOS: DMG package
  • Linux: compile the source code yourself, or download binary from third-party build

Note that the main branch can contain unstable code. If you want to build on a stable version, use a tagged version.

Troubleshooting and/or feature request

Please open an issue.

Build from source

Requirements
  • Rust: required to compile libcaesium. Make sure you have cargo executable on you $PATH
  • Qt6 SDK: binaries are built on 6.5.3 (open source)
  • libssh: macOS only
  • Sparkle: macOS only. Only version 1.27.1 is supported.

Build

Step 0 (macOS Only)

You need to set up Sparkle in order to compile the project

brew install --cask https://raw.githubusercontent.com/Homebrew/homebrew-cask/c6dfe6baf1639998ba1707f68668cf8fa97bac9d/Casks/sparkle.rb
sudo cp -R /usr/local/Caskroom/sparkle/1.27.1/Sparkle.framework /Library/Frameworks/Sparkle.framework
Step 1

You need to configure CMake first and the command is slightly different for all the platforms: Change the path in variables with the correct directories of the requirements.

Windows
cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version -G "MinGW Makefiles"
MacOS
cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version/macos -DLIBSSH_INCLUDE_DIR=/libssh/dir/include -DSPARKLE_INCLUDE_DIR=/usr/local/Caskroom/sparkle/1.27.1/Sparkle.framework/Versions/Current/Headers
Linux

Make sure you have all the requirements installed with you own package manager

cmake -B build_dir -DCMAKE_PREFIX_PATH=/path/to/Qt/version/gcc_64
Step 2

Then you can build with

cmake --build build_dir --config Release --target caesium_image_compressor
