For some business owners, looks only come second when getting a website. They focus on their products and the overall functionality of their sites. But did you know that about three-quarters of visitors judge a business by its website design? 

According to Stanford Web Credibility Research, 75% of people gauge a business’ credibility on how their website looks. That’s how crucial design is to a website, and for you to achieve this, you have to think out of the box. UI illustration can be the solution, and fortunately, Penji can help you with this. 

What is UI Illustration?

Before we get into the definition of UI illustration, let’s get to know what illustration is. An illustration is visual imagery created to interpret, depict, explain, or decorate. It is the drawing or picture that we commonly see in books, magazines, newspapers, and digital media.

Now place those illustrations on your website’s user interface (UI), and what you have is UI illustration. As illustration’s primary purpose is to communicate, using it on your website’s UI can be powerful. Let’s dig deeper into this.

Gets Your Message Across Better

Humans perceive messages better with images than plain texts. Sure, you can use pictures to get your word across, but will they give you the impact you need? In addition, first-time visitors on your site won’t read your content straight away. 

They’ll scan the pages first, then will stay longer if you give them a reason to. 

Creates a Visual Hierarchy

Smooth-flowing website navigation leads your visitors where you want them. Using illustrations to do this task can make it more straightforward and concise. You can create a story that will beautify your buyer’s journey.

Inviting and Welcoming

You can have your UI illustrations created to compel certain emotions you want to elicit from your visitors. You can make it lighthearted, welcoming, intriguing, and so many others. We can’t stress it enough that you will only be limited by your imagination when you use illustrations.


A character, map, or infographic that’s interactive can hold your visitors longer. Make them stay longer to try out that button or click on that map. They may even share your link with friends, and the possibilities can be endless.
