Also available within the batch operations include rotating, adding of watermarks, adding of text along with many image-adjustment features such as brightness and shadows. The interface of the program is plain and simple to navigate through.

XnConvert is a powerful image converter and processor that can perform a series of image manipulation actions for an entire batch of images.

The available actions include resizing, format conversion, cropping, metadata removal, color and contrast adjustments, rotation, and much more. You can also add watermarks or image frames to your pictures, apply image masks and choose from various image filters and effects.

Multiple actions can be stacked and previewed for each step, and you can also save the complete set of actions to a script file so they easily be reloaded later.

In the queue you can check out the name, size, date of creation and modification, EXIF date, properties, type, rating, and other data regarding image files.

So, you can add a mask, crop, mirror, rotate and resize pictures, change the color depth, clean metadata and adjust the DPI, as well as add text and watermarks. Furthermore, you can adjust the color balance and apply various filters (e.g. negative, posterize, normalize, saturation, sepia, blur, sharpen, soften).

Once you specify the new format and destination of the images, you can proceed with the conversion job. Furthermore, you can set file renaming rules (e.g. change case), enable XnConvert to keep the folder structure and metadata, and others.

The image processing tool runs on a moderate amount of system resources, has a good response time, supports multiple languages for the interface, quickly finishes a task and manages to keep a good image quality after conversion.
