Identicon is a library which generate an identicon image based on a string.

Here is some examples of awesome results!

Identicon example #1   Identicon example #2   Identicon example #3   Identicon example #4   Identicon example #5


The recommended way to install Identicon is through composer.

Just add the library to your project:

composer require yzalis/identicon


Images are generated in PNG format with transparent background.

The string can be an email, an IP address, a username, an ID or something else.

Generate an identicon

Create a new Identicon object.

$identicon = new \Identicon\Identicon();

Then you can generate and display an identicon image


or generate and get the image data

$imageData = $identicon->getImageData('bar');

or generate and get the base 64 image uri ready for integrate into an HTML img tag.

$imageDataUri = $identicon->getImageDataUri('bar');
<img src="<?php echo $imageDataUri; ?>" alt="bar Identicon" />

Change the size

By default the size will be 64 pixels. If you want to change the image size just add a secondary parameter. 512 x 512px in this example.

$identicon->displayImage('foo', 512);


The color is automatically generated according to the string hash but you can chose to specify a color by adding a third argument.

Color can be an hexadecimal with 6 characters

$identicon->displayImage('bar', 64, 'A87EDF');

or an array with red, green, blue value

$identicon->displayImage('foo', 64, array(200, 100, 150));

That's it!

Generate an identicon on SVG format

The only thing you need to change it this one:

$identicon = new \Identicon\Identicon(new SvgGenerator());
$imageDataUri = $identicon->getImageDataUri('bar');
<img src="<?= $imageDataUri; ?>" alt="bar Identicon" />

Everything should be ok.
