OpenToonz is 2D animation software for professional and amateur production, as well as school education. It runs on Linux, macOS, and Windows, and exports formats including AVI, GIF, MP4, PNG, Spritesheet, and WebM. Its tools cover scanning, digital painting, and compositing: the GTS scanner supports four scanning types and saves settings, while painting supports anti-aliased lines and keeps painting data separate from palette data. Compositing offers xsheet and timeline interfaces and combines effects through a node tree. The software supports raster and vector images, and can convert between colored binarized TGA sequence images and OpenToonz format. An effects SDK allows image-processing plug-ins. GTS is TWAIN-compatible but available only on Windows. OpenToonz is based on Toonz, which Studio Ghibli customized and used for many years. Its source code is available under the New BSD License. OpenToonz is free for commercial and non-commercial projects, with no free trial listed.
