OpenToonz is a free 2D animation program derived from the Toonz software family. It is used for producing animated films, TV series, and independent projects. The application supports both traditional frame-by-frame animation and digital production pipelines. Because it is open-source, users and developers can access the source code and adapt it for different creative needs. It runs on Windows, macOS, and Linux systems.

OpenToonz includes tools for drawing, scanning paper sketches, and converting them into digital frames. It provides support for keyframe animation, bone rigs, and various visual effects such as blurring and color correction. Users can work with raster and vector graphics in the same project environment. It also supports customizable brushes and editable node-based compositing.

OpenToonz is used in animation studios, education, and independent production projects. Artists can organize scenes, manage layers, and export sequences for video editing. The interface allows timeline control and asset management for complex scenes. It also integrates scripting options for automation and repeated tasks. It supports collaborative work through shared project files as well features.

OpenToonz remains suitable for creators who want a flexible and customizable environment for 2D animation production. Its open-source nature encourages community contributions and continuous improvement. The software adapts to different project sizes, from short clips to full-length animated works, supporting both learning and professional use environments.
