PDF Page Counter & Info
Instant page count plus page sizes, dimensions, and document structure stats — no upload.
About This Tool & Technical Logic
Answers the everyday questions before you print or submit: how many pages, what size are they (A4? Letter? mixed?), and how big is the file per page — a quick signal of embedded scans versus text.
Per-page dimensions come from each page's MediaBox, listed in both points and millimeters. Print shops, visa applications, and submission portals all impose page limits — this counts exactly, instantly, locally.
getPageCount() + per-page getSize() from pdf-lib; MB/page from file bytes.
