A strange thing happens when I create a new PDF from multiple JPEGs. Sometimes, individual pages will be radically different sizes.

I took two JPEGs and combined them into one PDF. One JPEG was 2546x3303, and one was 2550x3507. The PDF that came out with the first page being 35.36 in x 45.88 in, and the second was a (correct) size of 8.5 in x 11.69 in.

Why is the first page giant? How can I re-size it to 8.5 x 11.69?

Thanks
