SIF (Synfig Image Format) is an open-source vector graphics file format specifically designed for 2D animation and digital illustration. Developed by the Synfig Studio project, this format supports complex layered animations with vector graphics, allowing for scalable and resolution-independent graphics with advanced animation capabilities. It stores animation data, keyframes, and rendering parameters in an XML-based structure.
Supports lossless vector graphics, resolution-independent scaling, complex multi-layered animations, open-source compatibility, and extensive keyframe interpolation. Enables detailed animation with minimal file size and high-quality rendering across different display resolutions.
Limited software support outside Synfig Studio, steeper learning curve compared to raster animation formats, potential compatibility issues with mainstream animation tools, and less widespread adoption in professional animation pipelines.
Primarily used in 2D animation production, digital illustration, motion graphics, and independent film animation. Synfig Studio leverages this format for creating animated shorts, educational animations, web animations, and multimedia presentations. Graphic designers and animators use SIF for creating complex, scalable vector animations with precise control over motion and transformation.
