iResize can instantly resize a number of images into a different resolution. However it does much more than that.
Using its straightforward interface you can also save the resulting images into different image formats (Jpeg, Bmp, Tiff, Png and Gif).
For those who have bought a widescreen monitor (or a laptop that is equiped with one) and want to convert their 4:3 wallpapers into the 16:9 image resolution, this is easily done by simply checking on the “Wide” option and choosing the target resolution (1280 x 800 for instance).
Note that in order to execute it you will need the .NET 2.0 framework installed in your computer.
