Avatar Sizer is extremely simple to use. It is designed to resize images not to edit them.There is no upper limit to the size of image The Avatar you create can be any size from 1x1 pixels up to a maximum of 150x150 pixels, so it will be suitable for virtually all Forums, IMs etc.The Aspect Ratio of the image is retained when the image is resized.Images smaller than the "Maximum Width and Height" are not resized (i.e. they are not enlarged). Avatar Sizer uses "Smooth Resizing". This makes the Avatar image look very similar to the original, just smaller. Avatar Sizer may even make some Avatars look better than the original image.The resulting Avatar file can be saved as a JPG or a GIF. The default is JPG.
Avatar Sizer will resize the following types of images:
* Jpegs (JPG)
* GIFs (GIF)
* Bitmaps (BMP)
* Windows Meta Files (WMF)
* Enhanced Meta Files (EMF)
* Icons (ICO)
GIFs with transparent backgrounds are catered for and you can turn the transparency on or off. If you resize an animated GIF only the first image of the animation is saved, the rest are discarded. So, make sure the first image is the one you want and that you save the Avatar with a different filename. Avatar Sizer is Free for personal use.
