It is possible to convert your old HTML site code into a WordPress website. Static HTML sites still exist, and they still have a place on the modern Web. But if you are not a coding expert and you want to take charge of your site personally; it might be a good idea to move from static HTML to WordPress. That is where WordPress comes into play. WordPress is a content management system designed so that anyone can use it, regardless of skill level. You will not need to hire a developer for WordPress development, and changes are super simple. Manual conversion uses your current site's HTML code as a starting point. If you are going to attempt this conversion method, it is recommended that you have some coding experience. Specifically, you should know HTML and CSS, as well as PHP.
