I recently downloaded a free digikit, and all of the elements were at 33" wide. I have Photoshop, but it won't allow me to save them as PNG files, so I did some researching and found one that works great! It's called "FastStone Photo Resizer". I just used it, brought the entire folder of all of the papers, frames, elements in, set my re-size to 15% (which made them about 5" wide), and it re-sized them all.
Here's the link for more information:
