I use vector files on basically every animation I do. Here are some places that offer free, royalty free, free for commercial use vectors. Many also offer vectors for sale, so if you find a site that fits your need, they may become an ongoing resource for you, as they are for me.
1) VectorStock.com : Has 100’s of free vectors. It is primarily a pay site and most vectors are $1. You’ll have to create a log in to download; I buy from them all the time and this is my #1 resource for vector files.
2) Icondock.com : Also primarily a pay site. They have the best collection of social media icons I’ve found (for free). Definitely worth checking out.
3) QVectors.net : Lots of vector files and well organized. It seems to be primarily a link into the free vectors files on dreamstime.com, but you don’t have to log in to download.
4) FreeVectors.com : Self-proclaimed ‘world’s largest website which provides you Original Royalty Free Vector Art…” and they do have a lot. Only problem is, that it’s not super-organized; (there is, however, a search bar so you can use keywords).
5) VectorPortal.com : Does not have a lot of ‘high end’ vectors – i.e. corporate-style; DOES have a lot of music and stoner based files, so if you’re looking for more grunge or music video kind of thing, this is the definitely your place.
If you have a favorite spot for commercial free vectors, please share them. Post your comments below.
