A couple of fields need to be fitted with the source and destination folders for conversion, while the rest of the space holds all management options to define the output.
Easily set output size and quality
The application is a batch conversion tools, so loading items of interest is a pretty comfortable operation, meaning you need to load an entire directory of pictures. These can be under formats like JPEG, PNG, TIFF, BMP and GIF. Note, however, that there’s no possibility to select a different output format, so the result is the same as input.In terms of renaming parameters, these are quite easy to handle. You can choose to preserve aspect ratio just so output doesn’t differ a lot from input. You also get the chance to set width and height of the result, as well as the quality, through a dedicated slider.
To end with
