"The best library to generate custom PDFs"

5/5

What do you like best about IronPDF?

IronPdf generates PDF files from html code. The great thing about it is that it's pixel perfect. The pdf takes into account all the CSS unlike other libraries where the horizontal alignement doesn't always work. Furthermore, the headers and footer are easy to add. The licensing is also flexible. As a small consulting firm building software, I was able to get started easily first with the one month free trial. Review collected by and hosted on G2.com.

What do you dislike about IronPDF?

I've using IronPDF for six months, I still haven't found a use case where it's not working or has limited functionality. Review collected by and hosted on G2.com.
