About this pdf page count & info viewer
Find out what a PDF actually is before doing anything with it: how many pages it has, what size those pages are in points and in the paper size they match, whether the file is encrypted, and whatever title and author the document carries. It answers the question you have when a form says "maximum 10 pages" or an upload is rejected without saying why. Nothing is changed and nothing is uploaded — the file's structure is read in your browser and the file itself is left exactly as it was.
How the pdf page count & info viewer works
The PDF's structure is read directly: the page count, each page's width and height in points with its rotation, the encryption flag, and any Title and Author entries in the document metadata. Points are the PDF unit — 72 to the inch — so an A4 page reads 595 × 842 and US Letter reads 612 × 792. Nothing is rendered and nothing is rewritten; this only reports what the file says about itself.
PDF Page Count & Info Viewer examples
A 3-page A4 PDF

A US Letter document
Page size: 612 × 792 pt — the same 72 points to the inch, a different paper size
A password-protected PDF
Encrypted: Yes — page contents are not readable without a password
A file with no metadata set
Title and Author come back empty; most PDFs never have them filled in
Limitations & privacy
Unencrypted PDFs only, up to 20 MB and 400 pages. An encrypted file is reported as encrypted, but its page contents cannot be read without the password. Metadata is whatever the producing application wrote. Title and Author are frequently missing, left at a default, or simply wrong — a file titled "Microsoft Word - Document1" is reporting its origin, not its contents. Processing stops after 45 seconds and can be cancelled.

PDF Page Count & Info Viewer: frequently asked questions
How do I check how many pages a PDF has?
Choose the file. The page count appears immediately, along with the page size and any metadata. The file is not modified.
What are points, and what size is my page?
Points are the PDF unit of length, 72 to the inch. A4 is 595 × 842 points and US Letter is 612 × 792, which is how you tell the two apart when they look similar on screen.
Why is the title wrong or missing?
Because metadata is whatever the producing application wrote, and most never set it properly. A title like "Microsoft Word - Document1" tells you what made the file, not what is in it.
Can it read a password-protected PDF?
No. It reports that the file is encrypted, but the page contents cannot be read without the password.
Does it change my file?
No. It only reads. The PDF is left exactly as it was.
Is my PDF uploaded?
No. Its structure is read in your browser and nothing leaves your device.
