Convert Facebook Profile to a Facebook Page

There are number of things that needs to be taken care of before you convert your Facebook profile to a Facebook Business Page.

The tool will convert all your Facebook friends and your subscribers to your Facebook Page’s Fan and your profile picture will be converted to your Fan Page’s profile picture.
The other data like the photos and videos you uploaded and your sent and received messages won’t be carried over to your fan page. So if you want to preserve that data you can heed to this page, click on “Download a copy of your Facebook data.” at the bottom of the right pane and download an archive of all your data.

Appoint New Page and Group Administrators

When you convert Facebook profile to a page, you will no longer be able to administer the pages and groups you were earlier admin of. So you must appoint new admins (at least one) to all the pages and groups before converting Facebook profile to page.

Now you have all your data with you and you can start the conversion process. Visit this page and select the type of page you want to convert your profile to. You will also have the option to select the category once you select the type.
