We've got a pretty fancy online packaging designer! But if your art file is oversized, you're going to get an unfortunate error when attempting your upload.
Most vector file created in Illustrator are less than 2MB. Why is yours so large? The most common mistake we see is pasting of a raster image (.tif, .gif, .jpeg, or .png) into your vector art file. A classic example is the addition of a social media icon. Use only vector art (.ai, .eps) whenever possible. When vector art is unavailable, try the work-around demonstrated in this screencast. I was able to reduce a file from 4.55 MB to 1 MB with just a few clicks in my Illustrator CS6.
