I think I can answer the Photoshop question. It seems that 1.6 Mb size is the file size for PS to do its work in the application. If you save that file as a .psd, I suspect you’ll see a file size of 1.6 Mb.
I find the Save for Web dialog (in the File>Export menu) useful. You can choose the file type, compression amount, and see the original and compressed file size there.
