PDF info checker

The basics, before you dig deeper

Before editing, sharing or submitting a PDF, it helps to know a few basic facts about it: how many pages it actually has, whether it opens without a password, whether the text inside can be searched and copied or is just a picture of text from a scan. This tool reads all of that in one pass and shows it as a simple checklist.

What is checked

• File size and name, for a quick reference.
• Whether the PDF is valid, or broken and unreadable.
• Whether it is password protected, which stops most tools from processing it further.
• The number of pages.
• Whether the text is real, meaning selectable and searchable, or the pages are scanned images with no text layer, which matters for accessibility and for whether you can copy text out of it.
• Whether it carries a digital signature.

Why this matters before other steps

Knowing the page count before splitting or extracting pages avoids guessing. Knowing a PDF is password protected explains why another tool might refuse to open it. Knowing whether the text is real tells you whether you need OCR before you can search or copy from the document.

What it does not do

This is a quick health check, not a deep validation against the PDF specification or a check of whether the content itself is correct. For the document's title, author and other properties, use PDF metadata. For a closer look at a signature, use check PDF signature. Your file is read entirely in your browser and never uploaded.
