Illustration is a form of a conversation with your landing page visitor. You can use text, but too much reading content will make your visitor bored. Besides, a well-picked illustration has always been the best way to tell a metaphor.
Also, it is a good practice to mix multiple types of content: text, video, screenshot, photo, illustration, interactive animation, chart, etc.
Today we prepared a huge list of places where you can download vector illustrations for free. The sites will offer you illustrations in all styles the humanity invented so far:
- flat and isometric
- 3D and 2D (we love 3D!)
- static and animated
- SVG or bitmap
- monochromatic or multiple color
- solid or outline illustrations
Enough words! Let's discover the graphics 😬
