Edit PDF Metadata Update Document Properties

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.
