A 3D book cover is a book cover for an online book that looks 3D instead of the more common 2D online book covers. It is similar to a picture of the actual book except that it is computer-generated. The reason you would want to make a 3D book cover is that it will make your book stand out and become more noticeable to book consumers.
3D book covers are useful, but how does one make it? There are essentially two ways to make a 3D book cover. One way is to do it yourself. The other way is to hire someone to do it for you.
The best way to do it would be to hire someone with the necessary skills to make it for you. This allows access to a professional to help you with your 3D book cover, but it is also expensive. To hire freelance graphic designers, you can go to Upwork, Fiverr, or other well-known platforms.
The other way is to do it yourself. There are many websites that have pre-designed templates that you can use. You simply upload your artwork, choose a template, and then do some modification. You can also use software, such as Photoshop, to match your artwork with a downloaded template. This way is simple and does not take a lot of time, but it is also an approach which is error-prone and using a pre-designed template can give your book cover an unoriginal or artificial look.
Another way to make your 3D book cover is using a special software. This can take longer but allow you to make better looking 3D book covers. You can read more about this here.
