What PDF Page Size Viewer Does
Inspect the dimensions of every PDF page in millimetres, inches, or points directly in your browser.
A PDF page size viewer reports the width and height of each page and helps you identify whether a document uses A4, Letter, Legal, or custom dimensions.
This is especially useful for print preparation, scanner QA, mixed-format reports, and any workflow where layout consistency matters.
How to Use PDF Page Size Viewer
- Upload the PDF you want to inspect.
- Choose the measurement unit you prefer.
- Run the page size analysis.
- Review the table showing page width, height, orientation, and likely standard size.
- Download the report as CSV or JSON if needed.
- Repeat for other files whenever you need quick print or layout checks.

How the Output Is Created
This tool uses pdf-lib to inspect the document structure inside the browser. Instead of sending the file to a backend for parsing, the library reads the PDF header, metadata dictionary, and page objects locally. That makes the analysis fast and private, and it also means the report you download is based on the original file that never left your device.
Limitations and Tips
A common analysis mistake is treating the report as the final answer without checking the source file context. Metadata, counts, and sizes are useful, but they should still be interpreted with the document purpose in mind.
Another mistake is replacing the original source file immediately after download. A better practice is to keep the original until you have opened the result, checked a few pages, and confirmed that the new copy is the one you actually want to send forward.
For analysis tools, decide which fields actually matter before you upload the file. Sometimes you only need page count or dimensions, and focusing on that answer keeps the review faster and easier for the next person who uses the result.
It is also smart to think about the destination of the file before you process it. A PDF going to a government portal, client review, internal archive, print workflow, or chat share may need different choices for page selection, order, readability, or file weight.
Privacy and File Handling
Your document is processed in your browser and is not uploaded to FilesConverter.in. The page may download libraries and other assets over the network. Keep the original and check the new file before using it.
Yes. Browser-side PDF analysis is one of the safest ways to inspect a document, especially if you only need information rather than editing. FilesConverter.in does not ask you to create an account or store your PDF remotely.
If the PDF is password-protected, unlock it first with a local tool before trying to inspect the metadata or page measurements. That keeps the process predictable and avoids broken or partial reports.
