HTML-to-PDF conversion capabilities are designed to effectively handle complex layouts and CSS. The conversion process ensures that intricate HTML structures and detailed styling are accurately rendered in the resulting PDF. PSPDFKit uses a sophisticated rendering engine that supports modern HTML and CSS standards. This includes handling complex page structures, multicolumn layouts, and nested elements to ensure the PDF output matches the original HTML content as closely as possible. The conversion engine fully supports CSS, including advanced features such as media queries, flexbox and grid layouts, and custom fonts. This ensures that the visual appearance of the HTML content is preserved in the PDF, maintaining consistency with the original design.
