PDF metadata is hidden information embedded in every PDF — the title, author, subject, and keywords that document management systems, search engines, and screen readers use. The PDF Metadata Viewer & Editor lets you inspect and update these fields instantly, in your browser, with no file upload. If you also need to trim the document before sharing, the Remove PDF Pages tool lets you delete unwanted pages from the same PDF.
What Is PDF Metadata?
Every PDF contains a document information dictionary with these standard fields:
| Field | What it stores |
|---|---|
| Title | The document's title (separate from the filename) |
| Author | Who created the document |
| Subject | A brief description of the content |
| Keywords | Comma-separated terms for search and indexing |
| Creator | The application that created the PDF |
| Producer | The application that converted it to PDF |
These fields are invisible when you open a PDF but are read by document management tools, corporate search systems, and archiving software.
Why Metadata Matters
Corporate and legal archives
Document management systems index PDFs by their metadata fields, not their filenames. An untitled PDF with no author field is hard to find and hard to audit.
SEO for publicly accessible PDFs
Google indexes PDFs. A PDF with a descriptive title and keywords can rank for those terms.
Accessibility
Screen readers use the Title field to announce what document is open. A PDF with an empty Title is announced as the filename — often meaningless.
Software traces
The Creator and Producer fields often reveal what software generated the PDF. This is useful for workflow auditing or when troubleshooting PDF compatibility issues.

Common Use Cases
Fixing blank titles in archived PDFs
Scanned documents and converted files often have empty Title fields. Bulk-fix them before importing into a document management system.
Adding keywords before sharing
Adding keywords to a PDF makes it discoverable in corporate search tools and email search.
Removing author traces
Before sharing a PDF externally, you may want to clear or change the Author field, which often contains an employee's full name.
Checking Creator/Producer
Identify what software generated a PDF — useful when PDFs aren't rendering correctly and you need to determine the source application.
Privacy
Your PDF is processed entirely in your browser. No file is uploaded to any server. The metadata is read and written locally, and the updated PDF is downloaded directly to your device.
