We all want to create beautiful, user friendly and fast loading digital products.

One part of sustainable web design, which you probably heard me rambling about before, is to reduce the digital data weight by using less images. I don’t say “Don’t use any images at all”. I use them too. But there are other ways to enhance your web and app designs that are equally awesome and even more lightweight. So, how can we use less images without ending up with a white minimalistic website that doesn’t fit the brand?

One way to reduce images is to trade them for illustrations and icons. Both of them use a lot less data and are therefore great for speed, digital footprint and in the end your SEO ranking.

My favorite illustration collections

There are incredible illustration libraries, packs and sets out there that you can use for free or a small amount. Brilliant designers share them on all kinds of platforms to support other designers as well as to get their work out there. Attributions are always great (sharing love) and sometimes even required. More about the attribution requirements can always be found on the websites themselves.


Iconscout is a marketplace for icons and illustrations that you can download for free or as premium versions. There is a huge variety of styles and topics to be found on the platform. Just pick and choose your favorite.


Blush is an incredible library with free illustration packs, such as Open Doodles, Fresh Folk or Humaaans. You can playfully mix and match the illustrations according to your needs. For enhanced options they also offer premium features such as color customization and SVG download.


You fancy some more abstract design elements? Go with Scribbbles, a collection of funky vector graphics. They are fully customizable and will definitely bring every digital product to life.

LS Graphics

LS Graphics offers a couple of free and paid illustration kits. They cover various styles, themes and topics. By the way, the illustrations with a price tag can also be downloaded for free as PNGs and with attribution.

Isometric love

Create your own illustrations

If you want to get creative or just want to try something new, start creating your own illustrations. It can begin with simple lines. Or with tracing existing illustrations (of course, only for training purposes).

I love to design icons and illustrations. It’s so much fun, buuuuut it took me a while to get in there and I’m still at the very beginning. It’s a process. Scribbling here. Sketching there. Trying. Failing. Improving.

I love to encourage you to start illustrating because it is quite rewarding once you get the hang of it. Until then, just go with the awesome resources above or hire an illustration artist that does the work for you.


As you could see, there are soooo many great free and premium illustration resources out there, that it is incredibly easy to omit images. Yes, illustrations still have a data impact, but it is a lot less compared to data heavy content such as images and videos. Again, this doesn’t mean you have to do everything without images. It’s just an option to mix it up once in a while. Be creative. See what suits the brand best. And have fun with it!
