Automatic conversion from HTML to PDF.

To make product pages, order confirmations and quotations look authentic, a PDF document is much better than an HTML page. On the one hand, HTML is interpreted differently by each client, which leads to visual differences. On the other hand, HTML presentation in mail programs is only possible to a very limited extent for security reasons. 
In addition, your customer cannot save an HTML page as a file on the data carrier or conveniently forward it to the accounting department.

Not so with a PDF. It looks the same everywhere. And it is very easy to file, forward or print.
