What metadata does a PDF contain?+
PDFs store: title, author (often your real name or username), subject, keywords, the application that created it (Word, Acrobat, LibreOffice), creation date, modification date, and sometimes GPS coordinates if created from a photo.
How do I remove personal data from a PDF?+
Upload your PDF, click 'Clear All Metadata', and download the cleaned file. This removes author name, company, creation timestamps, and application data. The content of the PDF is unchanged.
Why does PDF metadata matter for SEO?+
Google indexes PDF files and uses the title tag as the page title in search results. A well-written PDF title and keyword metadata can improve how the document appears in search. Author and creation date are less important for SEO.
Is this tool safe for confidential PDFs?+
Yes. All processing happens locally in your browser using pdf-lib. Your PDF is never sent to any server. You can safely process confidential documents.
