How to Check PDF Page Count, Size and Properties Online

Before you send, print or convert a PDF, it helps to know what is inside it: how many pages, what paper size, which version, and whether it is protected.

Opening the file in a reader shows some of that, but not all, and not in one place.

This guide shows how to see it all at once with TAMPDF's PDF Info tool, and why that is useful.

What Is PDF Info?

PDF Info reads a PDF and reports its details. The file is only read, never changed, and nothing is saved.

What Details Does It Show?

• The number of pages.
• The size of every page in millimetres, with paper names such as A4 or Letter.
• The PDF version and the file size.
• Whether the file is encrypted, contains a fillable form, or has fast web view.
• Document properties: title, author, software, and creation and modification dates.

When Is It Useful?

• Before printing: confirm the page size and count so nothing prints on the wrong paper.
• Before submitting: many portals ask for a maximum number of pages or a specific size.
• Before converting or merging: check that all pages are the same size.
• Before sharing: see what author and software details the file carries.
• When troubleshooting a file that behaves strangely.

How to Check a PDF With TAMPDF

1. Open the PDF Info tool.
2. Drag your PDF into the upload area, or choose it from your device.
3. Press Check PDF.
4. Read the results: pages, sizes, version, security and properties.

Why Use a Browser-Based Checker?

The PDF is read locally in your browser, so it is not uploaded to any server. That makes it suitable even for private documents.

Tips for Best Results

• If the pages are not all the same size, unify them with Resize PDF.
• If you see author or software details you do not want to share, use Remove PDF Metadata or Edit PDF Metadata.
• If the file size is large, try Compress PDF.

Common Mistakes to Avoid

Assuming all pages share one size

Merged files often mix sizes. PDF Info lists the size of every page, so you can spot the odd one out.

Trying to read a password-protected file

A file that needs a password to open cannot be read without it. Files with only editing restrictions are shown as encrypted.

Trusting the file name

A name like final_v3.pdf says nothing about the contents. The properties show what is actually stored.
