The metapdf library is a lightweight Python library optimized for metadata extraction and insertion, and it is a fast wrapper over the excellent pyPdf library. It works by quickly searching the last 2048 bytes of the PDF before parsing the xref table, offering a 50-60% performance increase over directly parsing the table line by line.
