Sozi is a free presentation editor and player for SVG documents. It lays content out on a poster rather than a fixed slide sequence, then presents it through translations, zooms, and rotations. The editor creates and saves frames, supports undo and redo, and lets users change keyboard shortcuts in preferences. PDF and video conversion are integrated into the editor. Presentations can be embedded in HTML with an iframe and controlled by JavaScript from the containing page. Sozi runs on the web, Windows, macOS, and Linux, with offline access and presenter mode listed. Windows is distributed as a zip archive without an installer. A Docker setup combines Sozi with Inkscape and conversion tools. It is licensed under the Mozilla Public License 2.0, is not sold commercially, and accepts donations.
