HTML TO PDF API

Overview

This API is used to convert HTML to PDF. It is a simple API that takes HTML content and converts it to PDF. THe API is built using Minimal APIs and is intended to run on windows and docker container (linux).

Libraries

The API uses the following libraries:

• DinkToPdf - This is a .NET Core library that uses the WebKit engine to convert HTML to PDF. It is a wrapper around the wkhtmltopdf library. - MIT
• NReco.PdfGenerator.LT - HTML to PDF converter for .NET Framework / .NET Core (WkHtmlToPdf wrapper). - Commercial License
• PuppeteerSharp - Puppeteer Sharp is a .NET port of the official Node.JS Puppeteer API. It uses a headless browser (chrome) to convert HTML to PDF. - MIT
• Gotenberg - A Docker-powered stateless API for PDF files. - MIT
• iTextSharp 4.1.6 - iTextSharp is a port of the iText open source Java library for PDF generation written entirely in C# for the .NET platform. - Mozilla Public License and the LGPL.

The following libraries was used but I was not able to get them to work in both environments (docker/windows)

• IronPdf - IronPDF is a commercial library that can be used to convert HTML to PDF. - Commercial License
• PugPDF.Core - WkHtmlToPdf .net core wrapper
• SyncFusion - The Syncfusion HTML to PDF converter is a .NET Standard library that converts URLs, HTML string, SVG, and MHTML to PDF in .NET Core applications. This converter uses the advanced Blink rendering engine, thus generating pixel-perfect PDF from HTML or URL.
