Frequently Asked Questions

✅ Can I create a PDF entirely from C# code?

Yes. You can create a new PDF, add pages, and compose content with text, images, tables, shapes, and vector graphics. Page settings and drawing APIs give you control over the document’s layout and appearance.

✅ Is PDF creation suitable for high-volume automated workflows?

Yes. The APIs are suited to server-side and unattended document workflows such as on-demand reports, scheduled statements, batch conversion, document portals, and SaaS export features. Test your deployment against representative files and expected concurrency.

✅ Which source formats can I convert to PDF?

This page covers creation from webpages, HTML files and strings, SVG, MHTML, Word, Excel, PowerPoint, Markdown, common image formats, XPS files, and RTF content in supported environments.

✅ Will converted files keep their original formatting?

The conversion libraries are designed to preserve source layouts and visual content such as fonts, images, tables, charts, styles, and document structure. Exact results can depend on the input, available fonts, and the conversion settings selected by the application.

✅ Can I use PDF creation in web, cloud, and container applications?

Yes. PDF creation and the relevant conversion workflows can be integrated into web, desktop, server, cloud, and cross-platform .NET applications. Platform-specific packages or runtime prerequisites may apply to individual converters.

✅ Can generated PDFs be saved to a stream?

Yes. Stream-based output makes it straightforward to return a PDF from an API, send it to browser users, attach it to an email, or write it to cloud storage without relying on a local output file.
