A PDF metadata editor lets you view and change the document properties embedded in any PDF — title, author, subject, keywords, and creator fields. These properties control how PDFs appear in search engines, file managers, and document workflows, and are invisible in the page content itself.

How to Edit PDF Metadata
PDF metadata (also called document properties) is information stored inside the PDF file itself but not visible on any page. It includes the document title, author, subject, and keywords — the same fields you see when you right-click a PDF and choose "Properties." This tool lets you view and update all of these fields for free, without Adobe Acrobat.
Step 1: Upload Your PDF
Click the upload area to select your PDF. The tool reads the file locally — nothing is uploaded to any server. Once loaded, the first page is rendered as a visual preview so you can confirm you have the right document, and the existing metadata fields are populated automatically if the original document had them set.
Step 2: Edit the Metadata Fields
Update any of the editable fields: Title, Author, Subject, Keywords, and Creator. The Keywords field accepts a comma-separated list. Leave any field blank to clear it. The read-only panel shows page count, file size, and the original creation date — these can't be changed.
Step 3: Save and Download
Click "Save Metadata & Download" to generate the updated PDF. The tool applies your changes using the pdf-lib library, automatically updates the modification date to today, and downloads the result as metadata-updated.pdf. The page content is unchanged.
When Metadata Matters
Search engines index PDF metadata — a well-titled PDF with relevant keywords ranks better in Google file searches. Enterprise document management systems use author and subject fields for organization. If you're sharing a PDF publicly, check the author field doesn't contain internal usernames or machine names that reveal private information.
FAQ
Is the PDF Metadata Editor free?
Yes, completely free with no signup required. Edit metadata on as many PDFs as you need.
Does this tool upload my PDF to a server?
No. All processing happens in your browser using pdf-lib. Your PDF is never uploaded and remains completely private on your device.
What PDF metadata fields can I edit?
You can edit the title, author, subject, keywords, and creator fields. Creation date and modification date are shown as read-only — the modification date is automatically updated to the current date when you save.
Why would I need to edit PDF metadata?
PDF metadata improves document organization — search engines and file managers use title and keywords to index and display PDFs. Editors often add their name to the author field for attribution. Removing personal metadata is useful before sharing documents publicly.
Does editing metadata change the visible content of the PDF?
No. Metadata is stored in the document properties and not visible in the page content. Editing metadata doesn't affect the text, images, or layout of any page.
