Overview ​

Using the ComPDF Generation .NET Core library, you can achieve fast and bulk PDF generation in your application. We provide different methods for PDF generation, and you can choose the one that best fits your business scenario.

  1. Generating PDF from HTML templates: Simply create an HTML template once, and then use JSON data to populate the template for bulk generation of different PDFs while retaining the original page layout. This method supports inserting text, images, and dynamic tables, making it ideal for generating complex and elegant PDFs, such as reports, invoices, letters, and contracts.

  2. Converting HTML to PDF: Standard HTML files or HTML strings can be converted into PDF files, suitable for quickly converting existing HTML content to PDF documents.

  3. Generating PDF through Layout API: Directly create and control every element of PDF documents through code, providing the finest level of control. This method allows you to completely build PDF documents from scratch programmatically, making it ideal for scenarios that require precise control of document layout, dynamic generation of complex structured documents, or deep integration with existing code logic. The Layout API supports a rich set of element types (text, paragraphs, tables, lists, images, etc.) and provides a complete style system and flexible layout control.
