IrfanView has an Advanced button that gives you the opportunity to make a large number of different adjustments to the images such as crop, resize, DPI, color depth, rotate / flip, overlay, watermark and sharpen or blur functions to name just a few. The sheer amount of text and tick boxes might be slightly overwhelming for some, but there’s no denying the IrfanView batch function has a great deal of power behind it. Works on Windows 9x and above, a portable version is available.
