PDF Xpansion SDK by soft Xpansion is a modular software development kit for Windows applications that provides a broad set of APIs and components for creating, editing, viewing, converting, validating, and processing PDF, PDF/A, and XPS documents, alongside support for modern electronic invoicing standards such as XRechnung, ZUGFeRD, Factur-X, and EN 16931. The SDK includes specialized modules for PDF viewing, document combination and splitting, PDF/A compliance, and e-invoicing creation and receipt workflows, enabling developers to integrate document management, archiving, compliance, and business process functionality directly into desktop and enterprise applications. It also supports advanced capabilities such as PDF/UA accessibility, embedded XML data, document conversion, structured invoice validation, and customizable viewing interfaces, allowing developers to build solutions for document-centric workflows, digital archiving, regulatory compliance, document viewing, and automated invoice processing using a common set of PDF and e-invoicing development components.
The PDF Xpansion SDK 18.0.2 update introduces full SVG import capability, allowing developers to embed complete SVG files directly into PDF documents rather than being limited to basic SVG elements. This enhancement improves fidelity when working with vector graphics by preserving complex shapes, gradients, paths, and other advanced SVG features during PDF generation. As a result, applications can produce more accurate and visually consistent PDF output from modern SVG-based assets, reducing the need for graphic simplification, conversion workarounds, or manual adjustments while supporting a broader range of design and reporting scenarios. Note: This feature is not included in the license and requires an additional purchase - details and pricing available upon request.
