What is Edit PDF Metadata?
Edit PDF Metadata lets you update the title, author, subject, and keyword fields stored in a PDF document. Unlike Add PDF Properties which only sets new values, Edit PDF Metadata is designed for modifying existing metadata — the workflow assumes you are correcting or updating information that already exists in the document.
The tool uses pdf-lib to load the PDF, apply your changes via setter methods for each field, and save the result. The document content, layout, and visual appearance remain completely unchanged.
How to Use Edit PDF Metadata
- Upload a PDF by dropping it onto the upload zone.
- Enter the updated values for Title, Author, Subject, and/or Keywords. Only fill in the fields you want to change.
- Click Edit Metadata. The tool updates the specified fields and returns the modified PDF.
- Download the result as
metadata-edited.pdf.
Why Use Edit PDF Metadata?
Correct metadata ensures documents are properly cataloged in document management systems, searchable by the right criteria, and displayed with accurate information in PDF viewers and file explorers. Common use cases include correcting a typo in the document title, updating the author after a team member leaves, adding subject keywords for better searchability, or rebranding documents with new organizational metadata.
Privacy & Security
Your files never leave your browser. Every step — reading, updating metadata, and saving the PDF — happens on your own device using pdf-lib compiled to WebAssembly. Nothing is uploaded to Racira's servers, no copies are stored in the cloud, and no file data is transmitted at any point.
Frequently Asked Questions
How is this different from Add PDF Properties?
Both tools set the same metadata fields using the same underlying engine. Add PDF Properties is oriented toward setting metadata on new or untagged documents. Edit PDF Metadata is oriented toward modifying existing metadata. In practice, they produce the same result — use whichever name matches your mental model.
Can I remove all metadata?
No, this tool only sets individual fields. To strip all metadata from a PDF, use the Remove Metadata tool which clears title, author, subject, keywords, creator, and producer fields in one operation.
