DynamicPDF HTML Converter for .NET often takes between 1 and 5 seconds to convert a single HTML document to PDF, depending on factors such as network download time, page complexity, and overall processing requirements. This is expected because the HTML Converter uses the Chromium rendering engine to fully process HTML documents before generating the PDF output.

When processing large numbers of HTML documents, total conversion time can quickly grow if documents are converted sequentially. For example, converting thousands of HTML files one at a time could easily require hours of processing time. In these scenarios, using parallel processing and batch execution can significantly improve overall throughput and reduce total conversion time.
