The Nutrient SDK seamlessly integrates PDF conversion into your applications and workflows, allowing you to maintain the same document while changing its format without needing specific libraries for each format or relying on Microsoft Office installations. It's an essential tool for developers, backend engineers, and document pipeline designers, enabling them to transform contracts and reports into PDFs, convert PDFs back to editable Office formats, change images into PDFs, and save archival records in PDF/A format. It supports converting Word, Excel, and PowerPoint files to PDF, as well as reverting PDFs to DOCX, XLSX, or PPTX formats while ensuring that layouts, fonts, and tables remain intact. The Web SDK allows for client-side conversion of Office, TIFF, JPG, and PNG files directly in the browser, eliminating the need for document uploads, while the Document Engine is equipped for self-hosted, server-side batch conversions. The .NET SDK is capable of converting over 100 file types into PDF, including HTML, emails, and CAD files, with PDF/A outputs designed to comply with veraPDF validation standards for long-term document preservation.
