PDF Metadata Viewer
View a PDF's metadata and page dimensions - free.
Your PDF is read inside this page. It is never uploaded.
What this tool does
Choose a PDF and see its title, author, subject, keywords, creator, producer, creation and modification dates, page count, and each page's actual dimensions - read directly from the file's own metadata.
Reads a PDF's document metadata: title, author, subject, keywords, creator application, producer application, and creation/modification dates.
Reports the total page count and, if page sizes vary, lists every page's individual dimensions rather than assuming they all match.
Loads the file with pdf-lib's ignoreEncryption option, so its structural metadata can often still be read even from a PDF that has restrictions set.
Copies the entire summary - every metadata field plus per-page dimensions - as one plain-text block with a single click.
How to use it
- Choose a PDF.
- Review its metadata and page dimensions.
Why use this viewer
A PDF carries author, creator and date information that may be private, and page sizes matter for printing. Seeing them shows what a file reveals.
Why we built it
We built the PDF metadata viewer to report every page's actual dimensions individually, because a PDF can mix sizes. Convert pages with PDF to image and compare versions with compare PDF.
Handy alongside this: the Redact PDF, the Repair PDF and the Image to PDF.
Who this tool is for
- People checking who made a PDF and when
- Print and design staff checking page sizes
- Researchers vetting documents
When to use it
- Checking what a PDF discloses before sharing.
- Finding creation and modification dates.
- Checking page size and count.
- Auditing documents.
Why page sizes are checked individually
A PDF is not required to use the same page size throughout.
Nothing in the PDF format requires every page to share one size - a report can mix portrait text pages with a landscape chart page, for instance. Reporting a single dimension for the whole document would either be wrong for the pages that don't match it, or would hide a real structural fact about the file. This tool checks every page and only claims a single uniform size when every page actually shares it.
This is a read-only viewer, not an editor
There's no option here to change or strip a PDF's metadata - only to see it.
pdf-lib is fully capable of writing new metadata into a PDF - it has setTitle, setAuthor and similar methods this tool simply doesn't call. This tool only calls the matching getter methods: it reads the document's Info dictionary and displays it, and never modifies or re-saves the file. If you need to change or strip a PDF's metadata before sharing it, that requires a tool that writes new values back into the file - this one only ever shows you what's already there.
What you give it, and what you get back
| Item | Details |
|---|---|
| Input | One PDF. |
| Output | Title, author, subject, keywords, creator, producer, dates and page count. |
| Notes | Page sizes are listed. |
Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| Fields are empty | The file has no metadata. | This is normal. |
| An error mentions encryption | The PDF is password protected. | Unlock it first with the Unlock PDF tool. |
| Dates look odd | They are stored in a standard format. | Check your time zone. |
Assumptions and limitations
- An encrypted or password-protected PDF's content can't always be fully read - some metadata fields may be unavailable.
- This reads the document's own declared metadata fields - it can't tell you anything the file itself doesn't record, like the actual editing history beyond what a creator or producer chose to store.
Frequently asked questions
How do I view a PDF's metadata for free?
Choose your PDF and its title, author and other metadata fields appear instantly.
Can I see the exact page dimensions?
Yes - every page's width and height in points is shown, and the tool flags it if page sizes vary within the document.
Why are some fields showing a dash?
A dash means that field simply isn't set in the file - not every PDF has an author, subject or keywords filled in.
Does this work with password-protected PDFs?
Some metadata can usually still be read, but full access to an encrypted PDF's content may be limited.
Is my PDF uploaded anywhere?
No. Reading the metadata happens entirely in your browser - your file is never sent to a server.
Can I edit or remove a PDF's metadata with this tool?
No - this tool only reads and displays existing metadata; it doesn't write changes back into the file or strip any fields.
Can I copy all the metadata at once?
Yes - use 'Copy as text' to copy every field along with the page dimensions in one plain-text block.
