How to Edit PDF Metadata — Step by Step

PDF metadata includes the document title, author name, subject, keywords, and creation/modification dates. Editing metadata makes documents more searchable, ensures correct attribution, and removes sensitive information before sharing.

Click Save Metadata. The updated metadata is written into a new copy of the PDF in your browser.
Download the updated PDF. The original file is never modified — your download contains the new metadata.

Why does PDF metadata matter?

Metadata is indexed by search engines, document management systems, and Windows/macOS search. Correct metadata improves discoverability. Incorrect metadata — like the wrong author name or creation date — can be misleading. Before sharing a confidential document, use Privacy Scanner to check what metadata it contains.

Frequently Asked Questions

PDF metadata is descriptive information stored inside a PDF file but separate from its visible content. It typically includes the document title, author name, creation date, software that created it, and searchable keywords.

Common reasons include fixing auto-generated titles that show up in search results or document viewers, updating author information before sharing, adding keywords for better discoverability, or removing sensitive information like the creator software name.

No. Metadata is stored separately from the page content. Editing titles, authors, dates, and keywords does not alter any text, images, or layout visible in the document.

All standard metadata fields — title, author, subject, keywords, creator, and producer — are cleared. Dates are also removed. This can be useful for privacy-sensitive documents before sharing externally.

No. All processing happens locally in your browser using the @cantoo/pdf-lib library. Your PDF and any edits you make never leave your device.

If the PDF has an owner password that restricts editing, the tool may not be able to save changes. Use the Remove Password tool first to unlock the PDF, then edit its metadata.
