I took on a .NET project to create invoices after a customer's orders. I decided to utilize HTML with CSS Stylesheet to create PDFs. After searching for a while, I came across IronPDF. I have used the library for an extended period and I highly recommend it, as it simplifies the complexity of turning an HTML into PDFs. First, the software is very beginner-friendly - with extensive documentation, videos, and code examples. The library supports multiple inputs, including webpages, HTML, and formats of HTML5 and CSS3. Overall, IronPDF is an excellent piece of software. The extensive documentation combined with the ability to experiment and debug with your existing Chrome dev tools makes it both familiar and easy to use.
