Contenta Converter Premium lets you work with several images at once and apply multiple changes in batches. Compared to the basic version, it offers considerably more power when it comes to image management.
Like the basic version, the interface of Contenta Converter Premium is very simple. The toolbar across the top gives you access to the program’s main features, all of which are available in the Premium version. These include advanced features such as read/write of JPEG 2000 files, reading of RAW formats, PSD formats etc.
You can convert photos between formats (both popular and less common ones), reduce the size of images and automatically rename them and sort them into subfolders according to their metadata. Contenta Converter also lets you preview images and check the amount of space you save when optimizing their size.
In the Premium version, there are additional features such as the ability to flip and crop images, converting multiple PDFs to images and adding special effects.
However, the main problem with Contenta Converter Premium is the same as the Basic i.e. if your metadata for images is very generic or inaccurate, it doesn't work very well as it uses this information to identify files.
Overall though, Contenta Converter Premium is a very powerful tool for sorting, renaming, converting and manipulating images that have the correct metadata attached.
