About the PDF Page Counter
Drop in a PDF and instantly see how many pages it has, along with its page size and document details. It's the fast check for anything gated on length or format — confirming a page count before printing or paying per page, checking an assignment or submission meets a page requirement, verifying a scan came out at the right size, or peeking at who produced a file and when. Need the actual text content instead of just the count? Try PDF to Text.
The file is read on your device; nothing is uploaded just to count it.
How it works
The PDF is opened with pdf.js in your browser. The tool reports the page count directly from the document, then reads the first page's dimensions and the file's metadata dictionary. It shows:
- Page count — the total number of pages.
- File size — the size of the PDF on disk.
- Page size — the first page's dimensions in points and inches (a PDF point is 1⁄72 inch, so 595 × 842 pt is A4).
- Document metadata — title, author, producer and creation date, where the file records them.
Assumptions and defaults
- Page size is read from the first page. Most documents use one size throughout, so this is representative — but a file with mixed page sizes will only show the first page's dimensions.
- Metadata is shown only if present. Many PDFs leave title/author blank; those rows simply don't appear. The "producer" is usually the software that generated the PDF, not the person.
- Dimensions are rounded to whole points and one decimal inch.
- The creation date is shown as recorded in the file's metadata.
Limitations
- It reports the first page's size only — it doesn't scan for or flag pages of differing sizes within the document.
- Metadata can be missing or misleading. Author and title are often empty; the creation date reflects what the software wrote, which can differ from when you received the file, and any of it can be edited.
- It counts and inspects; it doesn't modify the PDF — no splitting or combining here, see Split PDF or Merge PDF for that.
- Encrypted or corrupted PDFs can't be read and will show an error.
Privacy
The PDF is inspected with pdf.js entirely in your browser. The file is never uploaded, stored, or sent anywhere.
