PDF metadata is structured information embedded in a PDF file that describes the document but does not appear in the visible text. It includes properties like the document title, author name, subject, keywords, creation date, and application that created it. The PDF Metadata Editor is a tool that lets you read and modify these properties directly, making PDFs easier to organize, search, and manage across your files.
Upload your PDF file to the tool. The editor reads the internal metadata dictionary (a hidden header section in the PDF) and displays all readable fields. You can then edit fields like the title, author, subject, and keywords, then save the updated PDF. The new metadata is written back to the file while the document pages and layout remain unchanged. Some metadata (like creation date) may be locked or read-only depending on the PDF's structure.
| Input | Result | Notes |
|---|---|---|
| A scanned report with title 'Report.pdf', no author, no subject | Edit to title='Quarterly Sales Report 2024', author='John Smith', subject='Q4 Analysis' | Makes the file easier to search and identify in file explorers and document management systems. |
| A downloaded invoice PDF with empty keywords field | Add keywords='invoice, 2024, vendor, accounting' for better indexing | Improves searchability in email, backup systems, and document databases. |
| An old PDF created by anonymous software, created date in 1970 | Update author to your name, verify the creation date reflects the actual date | Ensures the document metadata reflects its true source and creation time. |
Yes. The PDF Metadata Editor modifies only the hidden properties (title, author, keywords, etc.) and leaves the document pages, text, and layout completely unchanged.
This depends on the tool's privacy policy—most free online editors process files in your browser only, but you should verify. Never upload sensitive documents unless you trust the provider.
Not on the visible pages. Metadata is hidden. To view it, open the PDF in Adobe Reader or your editor again and check File > Properties or Info.
Common editable fields include Title, Author, Subject, Keywords, Creator (application), Producer, and sometimes CreationDate. Some fields may be read-only depending on the PDF's encryption.
Common reasons include organising files, improving searchability in document systems, removing personal information before sharing, and adding professional details to reports.
Most free tools handle one PDF at a time, but some allow batch uploads. Check the tool's features for bulk editing options.
