 QuestPDF presents a new approach to PDF document generation. Unlike other libraries, it does not rely on the HTML-to-PDF conversion which in many cases is not reliable. Instead, it implements its own layouting engine that is optimized to cover all paging-related requirements. Then, everything is rendered using the SkiaSharp library (a Skia port for .NET, used in Chrome, Android, MAUI, etc.).
