The PDF is opened in your browser tab and never uploaded. Passwords only unlock it in memory.

This PDF is password-protected

e-Aadhaar PDFs use the first 4 letters of your name in CAPITALS followed by your year of birth (e.g. RAVI1991). Bank statements often use part of your name, date of birth or customer ID.

The password only unlocks the file in this tab. It isn't saved or sent anywhere, and the copy you download has no password.

What it shows

  • Properties: title, author, subject, keywords, the app and PDF producer, created and modified dates with time zone.
  • Custom and XMP data: company names, document IDs and anything else apps added.
  • Comments and form values: notes, who wrote them, and filled-in fields.
  • Attachments, bookmarks and signatures: embedded files, outline titles and digital signature fields.

Properties are only half of it. If the PDF was redacted, the PDF Redaction Checker finds text still hiding under black boxes. For photos, use the EXIF viewer.

Questions

Where does PDF metadata come from?

Mostly from the app that made the file. Word processors, scanners and PDF printers fill in the author from the computer's user name, the software and its version, and the dates. Some add a company name or a document ID.

Is the metadata visible when someone opens the PDF?

Not on the page. It sits in the file's properties, where anyone can see it in their PDF reader's properties window or with a viewer like this one.

How do I remove it?

Open the PDF in Blur Document and export it: every page is rebuilt from pixels and the properties, XMP, comments, form fields and attachments are left behind. The trade-off is that the text is no longer selectable.

Does it work on password-protected PDFs?

Yes. Type the password when asked; it only unlocks the file in your browser and isn't stored or sent.
