There are trends on the web that last days or weeks and there are things that became a classic form of expression of the geek culture and are still interesting to explore after many years. ASCII Art is one of these things. ASCII art allows you to represent forms by using characters. So here in this post I’ve collected some cool Javascript libraries that allow you to transform any image, video and text into ASCII art.

ImgToAscii

A JavaScript implementation of a image to Ascii code. The ascii art depends on a monospace font to work properly. You should consider that 1 pixel in your image is going to be translated to 1 char in Ascii. e.g.: if a image is 100 pixels wide, it’s going to take 100 chars of space on your page, unless you do something about it.
