‘Asciiconvert’ is a wonderful utility which help you to make ASCII character of any image. You can fully make an image as a text. Even the conversion is also fast. You can use any format [They have not mentioned format limitation, but I tried with jpeg, gif and png]. You may use it to write testimonials for your friends on social networks.
