Simple tools for understanding PDFs.
PDF Inspector is built to help you check important PDF page properties without making the process complicated.
About PDF Inspector
PDF Inspector is an online collection of focused tools for checking PDF files.
PDFs are used everywhere. People use them for reports, forms, invoices, school work, business documents, applications, manuals, and many other types of files.
A PDF can look correct when you open it, but there can still be important details that are not easy to see.
A page may use A4 size while another page uses Letter size. One page may be portrait while another is landscape. A document may also contain more or fewer pages than you expected.
PDF Inspector was created around a simple idea: checking these details should not have to be difficult.
Our tools focus on specific PDF properties so you can choose the check you need and get a clear result.
Make PDF information easier to understand.
Many PDF tasks can become confusing because there are many different settings and terms.
You may only want to answer one simple question: Is this PDF A4? How wide is this page? Is this page portrait or landscape? How many pages are in this file?
You should not need to learn complicated PDF software just to answer a basic question.
Our goal is to provide focused tools that help you inspect one PDF property at a time.
We aim to keep the experience simple, clear, and easy to follow for both beginners and experienced PDF users.

- Helpful PDF information
PDFs contain more information than you see.
When you open a PDF, the first thing you notice is the content. You see the text, images, tables, and other parts of the document.
But the PDF also contains page information. This information can affect how the file looks, prints, or works with other software.
For example, page dimensions can affect printing. Page orientation can affect the layout. Different page sizes can make a document look uneven when printed.
These details are easy to miss when you only look at the document on your screen.
PDF Inspector gives you a way to inspect these properties directly so you can make better decisions about your PDF.
Focused PDF inspection tools
Each tool is designed for a specific type of PDF check.
Page Size
Check the paper size used by PDF pages and understand the page format.
Dimensions
Check the width and height of PDF pages when exact measurements matter.
Orientation
Find out whether PDF pages are portrait or landscape.
Check common PDF requirements in one place.
PDF Inspector includes more than basic page size and dimension checks.
You can also check whether pages match A4 or Letter formats. If a document contains pages with different sizes, the Mixed Size Checker can help you find them.
The Page Count tool helps you quickly find the total number of pages in a document.
For users who need more detailed information, the Page Box Inspector can show important page boundary information.
Together, these tools provide a simple starting point for understanding the structure of a PDF.
Simple is better when the task is simple.
We believe a PDF inspection tool should be easy to understand.
If you need to check page dimensions, you should be able to find a dimension checker. If you need to check page count, you should be able to find a page count tool.
This is why PDF Inspector uses separate, focused tools instead of putting every PDF function into one large interface.
A focused tool can make it easier to know what you are checking and what the result means.
We also use clear headings and simple language throughout the site to make the tools easier to use.

When can PDF Inspector help?
There are many simple situations where checking a PDF can be useful.
You may receive a PDF from another person and want to know its page size before printing it.
You may combine several PDF files and want to check if all pages use the same size.
You may need to submit a document that requires A4 or Letter pages.
You may also have a PDF with a wide table and want to know which pages are in landscape orientation.
In each case, a focused PDF inspection tool can help you find the information faster.
We explain PDF terms in simple language.
PDF technology includes many technical terms. Some of them can be difficult to understand if you do not work with PDFs every day.
PDF Inspector aims to make common PDF information easier to understand.
When a tool uses a technical term, we try to explain what it means in a clear way. This is especially useful for information such as page dimensions and PDF page boxes.
You should be able to use a PDF tool without needing to become a PDF expert first.
Useful information for advanced PDF work.
Most users only need basic PDF information. But some documents require a closer look.
This is where PDF page boxes can become useful.
Page boxes describe boundaries inside a PDF. Different boxes can be used for viewing, printing, trimming, bleeding, or other publishing tasks.
The PDF Page Box Inspector gives users a way to inspect this information without needing to search through the PDF structure by hand.
Useful tools should feel simple.
Clear
We aim to present PDF information in a way that is easy to read and understand.
Focused
Each tool has a clear purpose instead of trying to do everything at once.
Practical
The tools focus on PDF information that can be useful in real document work.
