Synfig Studio Project

A SIF file is a project created by Synfig Studio, an open source program used to create film-quality 2D animations. It contains an animation which includes a canvas populated with shapes, brush or pencil strokes, text, and position, angle, radius, width, tangent, and vertex handles.

SIF files are one of three file formats used by Synfig Studio. Since SIF files are uncompressed they tend to get pretty large. You can save your project as a .SIFZ file, which compresses its contents for a smaller file size. Synfig Studio also uses .SFG files for embedding images, audio, etc. into the project which is then compressed with Zip compression.
