Module pdf_meta 

PDF metadata extraction (page count).

Uses lopdf to read the document catalog and return the page count. Designed for bulk extraction — returns None on any parse error so one bad file doesn’t stop a batch job.

Functions

extract_page_count

Page count for a single PDF. Returns None if the file can’t be parsed.

extract_pages_batch

Batch page-count extraction with parallel parsing. Returns (path, pages) pairs only for PDFs that parsed successfully.
