I think you could if you have photoshop, but otherwise the only way I can think of is to copy and paste it to something like "Paint" and recreate from there, but quality might be weak.

If you don't have photoshop, email the files to me and I'll have a go if you like.

I cant cut and paste because the PDF has security it will not allow editing .
I have photoshop but wont open file without the password.
