This is a category called Isekai meaning other world essentially
and if you go to the sites and scan thru the listings you will see a
great many of these as it has become a popular category.
If I want to find something I go to DuckDuckGo a discreet search engine
and enter manga and hit enter. <

I go twice a day and look for my interest which sadly is not isekai.
Not all isekai stories deal with reincarnation but many do. The only
problem is the numerous stories out of China which try to imitate
Japanese Manga but don't seem able to get it quite right.

who only existed as images poorly printed on cheap paper
