Hello, for my projects i work with Adobe Illustrator and all of the Vector-Files in Billionphotos.com are as PSD, is it possible to get the .ai files?

Hello, I have downloaded some vector images and I am looking for an easy way to convert the vector images to illustrator. Some elements from the vectors I can copy to Illustrator, others I have to...
