Edit PDF Metadata: free online, fast and secure
Every PDF carries hidden properties: title, author, subject, keywords, the app that created it and dates. These show up in browser tabs, search results and file properties, and can reveal names you did not intend to share.
This tool displays the current values and lets you edit or clear them. Setting a good title and keywords also helps PDFs you publish online appear properly in Google.
How to use Edit PDF Metadata
- Upload the PDF. Current metadata appears in editable fields.
- Edit or clear. Change any field, or press “Clear all fields”.
- Save. Download the PDF with the new properties.

Good to know
There are two kinds of PDFs: digital PDFs created from Word, Excel or a website, which contain selectable text, and scanned PDFs, which are just photos of paper pages. Tools that edit pages, like Edit PDF Metadata, work with both. Tools that read text work only with digital PDFs. If you can select a word in your PDF viewer, your file has a text layer.
