Aspose.Slides FOSS
Create, read, and edit PowerPoint presentations — free and open-source, available for .NET, C++, Java, and Python.
Aspose.Slides FOSS is a suite of free, MIT-licensed open-source libraries for creating, reading, and editing PowerPoint presentations, with no Microsoft Office dependency and no native extensions. Each edition works with PPTX files and supports adding slides, inserting shapes, tables, and connectors, formatting text at character level, applying visual effects (shadow, glow, blur, reflection), and round-tripping files safely without losing unknown XML content. Every library in the suite installs with a single package manager command and runs identically on Windows, macOS, Linux, Docker, and serverless.
