Using NodeJS to asciify images

In this post, I'll describe how to use image-to-ascii for converting images into ASCII art. This is built by me and it is open-sourced on GitHub.

It's super easy to use. Let's take a look.


You have to install GraphicsMagick before using this package:

$ sudo apt-get install graphicsmagick # Ubuntu
$ brew install graphicsmagick         # Mac OS X


After the prerequisites are installed, you can install the module: npm install image-to-ascii. Then you can start ASCIIfying images.

Let's use this Octocat in our tests. The url of the image is

So, to convert this image into ASCII art, you'll have to do the following below:

// Load the library
var img2ascii = require("image-to-ascii");

// Convert an octocat into ascii :)
img2ascii("", function (err, result) {

The result is:

Saint Nicktocat

This is the default behavior. We can modify it using an object instead of a string.

Don't forget to browse the code and documentation on GitHub... and ASCIIfy the world!
