Movavi Photo Editor is a program designed for Mac users as an alternative to working with Photoshop or other expensive image editing tools. This application provides you with a nicely-designed and straightforward interface, is available in various languages, and works with many image formats.
All integrated utilities are nicely organized on the right side of the interface, each with individual output settings. You can crop, resize, watermark, rotate, and even adjust the levels of brightness, hue, temperature or tint.
But the tools I like the most are the ones that allow me to remove objects or backgrounds from the input files. The application provides you with detailed instructions to help you get the results you require.
You can find various freeware utilities that offer you the same amount of features as Movavi Photo Editor. However, the developers of the latter kept things simple and at reach, without displaying dozens of functions on the main window. So, even an average Mac user can easily and immediately obtain the results he or she needs.
As a conclusion, I'd say it's worth buying this program only if you don't mind spending a few bucks for an app that offers you features which can be found in tools like GIMP.
