A small utility that I wrote to change image format. You don't have to open the image in a application to change the format just right click a image in a folder and in the context menu choose CtmImageFormat and in the submenu choose any convert to you need and Voila done. Easy to use and it is very fast for conversion in all format.
Image format supported:
*. bmp Bitmap (BMP) image format.
* .gif Graphics Interchange Format (GIF) image format.
* .jpg Joint Photographic Experts Group (JPEG) image format.
* .png W3C Portable Network Graphics (PNG) image format.
* .tiff Tagged Image File Format (TIFF) image format.
* .wmf Windows metafile (WMF) image format.
