How to View PDF Metadata in Your Browser
Add Your PDF
Drag a PDF onto the upload area or click Choose PDF File to select one from your device. PDF.js reads the file in the browser when supported. For sensitive documents, confirm the active workflow before processing.
Click View Metadata
Press the View Metadata button. The tool reads the document's Info Dictionary and page count without rendering any pages, so even large PDFs load almost instantly.
Review the Properties
Inspect the Title, Author, Subject, Keywords, Creator and Producer, creation date, last modified date, and total page count. Empty fields mean the value was never set in the source file.
Which Metadata Fields This Tool Reads
This viewer reads the standard PDF Info Dictionary fields plus the page count. The table below lists each field, where it comes from, and why it matters. All reading happens in your browser; nothing is written back to the file.
| Field | Source | What It Tells You |
|---|---|---|
| Title and Subject | Info Dictionary | The document name and topic set by the author, used by readers and search indexing. |
| Author | Info Dictionary | The person or organization credited with the document. |
| Keywords | Info Dictionary | Search terms the author attached to help locate the file. |
| Creator and Producer | Info Dictionary | The app that authored the content and the software that wrote the PDF. |
| Creation and Modified dates | Info Dictionary (D: format) | When the file was made and last changed, converted to YYYY-MM-DD HH:MM:SS. |
| Page Count | Document structure | The total number of pages, read without rendering them. |
When This Viewer Is the Right Choice
Checking a Document's Origin
Use it to see which application created a PDF and when. The Creator and Producer fields often reveal whether a file came from Word, Acrobat, LibreOffice, or an export pipeline.
Verifying Before Sharing
Open a PDF to confirm what Title, Author, and Keywords it carries before you send it out, so you know exactly what document properties travel with the file.
Privacy-Sensitive Files
Because the PDF is read locally in your browser, this is a good fit for contracts, reports, or any document you prefer not to send to a server.
Quick Page Count and Dates
When you only need the page total or the creation and modified timestamps, this reads them in one step without opening a full PDF editor.
Common Problems and Fixes
Most fields are blank
Metadata fields are optional in the PDF format. Scanned documents and files exported by some apps leave Title, Author, and Keywords unset, so they correctly display as empty.
Password-protected PDF will not open
Encrypted PDFs cannot be read without the password. Remove the protection first, then load the file again to view its metadata.
I want to change a value
This tool views metadata only. Editing requires rewriting the PDF binary, which is not part of this browser-side viewer, so the fields are shown for reference and not saved back.
An error appears or the file will not load
Confirm the file is a valid PDF rather than a renamed image or document. Corrupted or partially downloaded files can fail to parse; try re-downloading the original PDF.
