PDF Metadata Viewer
See the document properties stored in a PDF in one table: title, author, subject, keywords, the creating application and PDF producer, the creation and modification dates, the language and the PDF version, plus the page count, the paper size and whether the file is encrypted, optimized for fast web view, has form fields or contains signature fields. Nothing in the file is changed.
Frequently asked questions
Which properties are shown?
Title, author, subject, keywords, creator (the application that made the original document), producer (the software that wrote the PDF), the creation and modification dates, the language and the PDF version. The table also shows the page count and page size and whether the file is encrypted, linearized, has a form or contains signature fields.
Where does the information come from?
The text properties come from the document information dictionary of the PDF, read with the pdf.js engine. Values that are missing or empty are shown as Not set. XMP metadata streams are not listed separately.
How are the dates shown?
Dates are converted to ISO 8601 in UTC, such as 2026-11-12T09:30:00.000Z, so they can be compared regardless of the time zone stored in the file. A date that is missing or cannot be parsed is shown as Not set.
How is the page size given?
In points and millimeters for the visible area of the first page, for example 612 x 792 pt, which is US Letter. If the pages have different sizes, the table says how many distinct sizes there are and which size page 1 has.
What does fast web view mean?
A linearized PDF, also called fast web view, is arranged so the first page can be shown before the whole file has downloaded. It matters for large files served on the web and has no effect on the content.
Does Yes under signature fields mean the signature is valid?
No. It only means the file contains signature fields. The tool does not verify certificates, so use a PDF reader with signature validation to check who signed and whether the file changed afterwards.
Can I read a password protected PDF?
Yes. A PDF that only has an owner password opens without one, and for a file that needs a password to open, enter it in the password field. The password is not returned in the result.
Is my file modified or stored?
No. The tool only reads the file and returns the table as text. The file is processed in memory for this request only.
How do I change the metadata?
Use the PDF Metadata Editor, which sets the title, author, subject, keywords, creator and producer. It leaves the page content as it is and updates the modification date.
What are the limits?
PDFs up to 10 MiB and 200 pages. Processing stops after 30 seconds, which is far more than reading the properties takes.
