PDF to HTML Converter

Quickly Create High Quality PDFs

With HiQPdf Library you can convert PDF pages to HTML documents using the HiQPdfPdfToHtml class. You can convert to HTML documents encapsulated in HiQPdfPdfPageHtmlCode objects in memory using the PdfToHtmlConvertToHtml(String, Int32, Int32) method or to HTML files using the PdfToHtmlConvertToHtmlFiles(String, Int32, Int32, String, String) method. There is also a special method PdfToHtmlRaisePageConvertedToHtmlEvent(String, Int32, Int32) which can be used to convert the PDF document pages to HTML one by one in memory to avoid high memory usage for large PDF documents. The HiQPdfPdfPageHtmlCode objects can be disposed when they are no longer necessary.
