I know I have done this before, so I'm sure it's possible, I just forget how to do it. There's a way to tell convert to grab a specific page of a PDF, and I'd like to keep the format of that page as PDF.
Use convert to grab a specific page from a PDF file

ImageMagick is a tool for bitmap images, which most PDFs aren't. If you use it, it will rasterize the data, which is often not desirable.
Pdftk can extract one or more pages from a PDF file.
If you have a LaTeX installation with PDFLaTeX, you can use pdfpages. There's a shell wrapper for pdfpages, pdfjam.
Another possibility (overkill here, but useful for requirements more complex that one page) is Python with the PyPdf library.
