# PDF Info

See everything a PDF says about itself with our PDF Info tool. It reports the PDF version, page count, every page size in points and millimeters with the paper name, title, author, producer, dates, language, encryption, tagging, fast web view, forms, signatures and attachments in one clear table. Useful for editors, printers and developers who need to check a document before they publish, print or process it.

## Frequently asked questions

### What does PDF Info show?

It shows the PDF version, file size, page count and page sizes, the title, author, subject, keywords, creator application and producer, the creation and modification dates and the document language. It also tells you whether the file is encrypted, tagged for accessibility, linearized for fast web view, holds a form or digital signatures, and how many attachments it carries.

### How are page sizes reported?

Each size is given in points, the unit PDFs use, and in millimeters, together with the orientation. Common paper sizes such as A3, A4, A5, B5, Letter, Legal and Tabloid are named when a page matches within two points. Pages that share a size are grouped, so a mixed document lists each size with its page numbers.

### Does the tool account for rotated pages?

Yes. When a page carries a rotation of 90 or 270 degrees, the width and height are swapped so the size matches what a viewer displays. The orientation, portrait or landscape, follows the displayed size as well.

### Where do the title and author come from?

They come from the document information dictionary that the creating application writes into the PDF. Fields the file leaves empty are shown as none. The tool reads the values as they are and does not guess them from the text on the pages.

### In which time zone are the dates shown?

The creation and modification dates are converted to UTC and shown as year, month, day and time. A PDF stores its own time zone offset with each date, and the tool applies it before converting, so the moment is exact even when the file was made elsewhere.

### What does tagged mean?

A tagged PDF carries a structure tree that describes headings, paragraphs, lists, tables and reading order. Screen readers rely on it, and it is required for accessible documents such as PDF/UA. The tool reports a PDF as tagged when it marks itself as tagged or contains a structure tree.

### What is a linearized PDF?

A linearized PDF, also called fast web view, is arranged so the first page can be displayed before the whole file has downloaded. It matters for large documents served on the web. The tool reports whether the file declares this layout.

### Can I check a password protected PDF?

Yes. Enter the password in the password field and the tool opens the document with it. A PDF that only restricts printing or copying opens without a password. The password is used for this request only and is never shown in the result.

### How large can the PDF be?

The file can be up to 10 MiB with at most 200 pages. Larger documents are refused with a message, and you can split them first and check the parts. The PDF Page Count tool counts pages of much longer documents.

### Does the tool change or keep my PDF?

No. The document is read in memory for this request only and is neither modified nor stored. Only the report is returned to you.
