Being a freelance writer I have written several articles online which I need to back-up offline. It is advisable to have a copy of our articles in case the website closed down and it is still a good practice to save for documentation. Aside from MS Word file, having an html file copy is great where you can copy the page as is.
One online tool that converts an html webpage to PDF is htmlpdf.com, it is very useful to me. I have used other html converter but others have limitations. It is easy to use just copy and paste the URL link and press “get PDF”.
I hope it will help you as much as I do. Here is the link: www.htmlpdf.com/
