HyperDither

If you want to apply an original effect to an image without having to use photo editing software, HyperDither can help you by applying a technique called dithering.

This technique is used in printing to present a wider variety of colors by concentrating dots or pixels on the screen. The final effect produced by HyperDither is in black and white, but that doesn't mean it's any less impressive.

To convert an image, all you have to do is to drag it to HyperDither's interface and the program will take care of the rest. In addition, you can improve the results by applying contrast or sharpening.

Then you have the option to save the resulting file in the following formats: BMP, JPEG, MacPaint, Photoshop, PICT, PNG, QuickTime Image, SGI Image, TGA, or TIFF.
