Magic Mockups is a new website from Kaspars Sprogis that generates ‘real-life’ mockups for you in no time at all.
The website works by using hi-res images from places like Unsplash, then after you chosen an image that you want to work with, upload your artwork that you want to appear on the screen.
There are screen overlays for a more realistic look, and a cropping/positioning tool. You can also add multiple screens per environment. It has to be said that there needs to be more base images to choose from, but this is a new website and I’m sure more will be added shortly.
