PDF metadata editor
Find out what hidden information your PDFs carry, change it or wipe it completely before sharing them.
What changes and limits
- The document info (Info), XMP, language and show-title preference are edited. Saving removes orphaned objects so deleted metadata is not recoverable from the file.
- Pages and their content are untouched, but metadata inside embedded images, attachments, comments or signatures is not removed. Saving invalidates any digital signatures in the PDF.
- Encrypted or password-protected PDFs cannot be edited without removing the protection first.
- Everything happens in your browser: files are never uploaded.

A PDF often carries more than you can see: the name of whoever created it, the company, the program and its version, dates and sometimes an edit history in the XMP block. Many editors change the document info but leave the XMP intact, so the "deleted" data is still there and Acrobat shows it. This editor reads both, explains in a report what identifying information the file contains and lets you change or wipe it. When saving it also removes objects left unreferenced inside the file, because deleting an entry is not enough if the data is still written in the PDF.

Frequently asked questions
What metadata does a PDF have?
The document info (title, author, subject, keywords, creating app, producer and dates), custom fields added by some programs and an XMP block that may repeat that data and add identifiers or an edit history.
Why does Acrobat still show the old author?
Because Acrobat prioritizes XMP and many tools only change the document info. The "Sync with document info" option rewrites the XMP with the same values.
Does removing metadata erase all hidden information?
It removes the document info, XMP, private app data and orphaned objects. It does not remove metadata inside embedded images, attachments, comments or layers, nor text hidden under other elements. For sensitive documents review those too.
Does it affect digital signatures?
Yes. Any change to a signed PDF invalidates the signature, so edit the metadata before signing the document.
Are my PDFs uploaded to a server?
No. Files are read and saved in your browser; nothing leaves your device.
