reaConverter is one of the fastest programs that allows you to convert images en masse, introducing certain changes or effects to them along the way. The free version of reaConverter, Lite, allows you to convert images between five formats: BMP, GIF, JPEG, PNG, TIFF.

It uses the same multi-threaded engine as the paid releases for processing, giving it impressive performance. In addition, it contains all the possibilities of modification from the full version, so you can change the size, rotate them by any angle or add watermarks in a selected place. Further operations remove JPEG compression artifacts, anti-aliasing, noise and coarse lens geometry correction.

It's a good idea to do these tasks before overlapping effects, cropping a photo, or adding frames. There was no shortage of possibility to adjust the brightness, color saturation, sharpening and applying different filters to the photos. Modification queues can be saved for reuse, as well as file lists.

After installing the program, we can use the program limited to five files per operation. Free registration allows you to take full advantage of the Lite version (5 file formats and all processing capabilities). If its capabilities turn out to be too small, you can buy licenses for more extensive versions.

The differences are described on the manufacturer's website.
