A client of ours made me aware of this really big archive of free SVG illustrations.
What’s cool about it?
You can apply your brand’s main color on the site before downloading the SVG file.
The licensing is “do whatever you want with it”. You can use it for commercial or personal purposes without crediting the source.
And it’s a huge archive of SVG illustrations, that covers all the typical nerdy/techie needs but also lifestyle elements, like Dua Lipa. (?)
By the way, a very easy way to customize and combine SVG graphics is using Figma. Just drag and drop your SVG files in Figma and further edit them, combine them, and export them again. Learn more about Figma.
