Edit PDF Metadata
Load a PDF to see its document metadata, then edit the title, author, subject, and keywords and download the updated file. You can also clear every field to strip identifying metadata before sharing. Everything runs in your browser with pdf-lib, so the PDF never leaves your device.
How to edit PDF metadata
- Drop a PDF in, or click to browse. The current metadata fills the form.
- Edit the title, author, subject, or keywords, or clear them all.
- Click Save and download to get the updated PDF.
Examples
Fix the title on an exported report
Title "Document1", Author "user"
Title "Q3 Report", Author "Jane Doe", saved to a new PDF
Frequently asked questions
Is my PDF uploaded anywhere?
No. The metadata is read and rewritten entirely in your browser with pdf-lib. The PDF never leaves your device, so confidential documents stay private.
Which fields can I edit?
The document Information dictionary fields you most often need: title, author, subject, and keywords. Enter keywords separated by commas and each becomes its own keyword.
Can I remove or strip metadata from a PDF?
Yes. Use Clear all to blank every field, then save. This empties the title, author, subject, and keywords in the Info dictionary, which is useful before sharing a file publicly.
Does editing metadata change the page content?
No. Only the document information fields are written. The pages, text, and images are untouched, so the visible content of the PDF is unchanged.
Why do some fields stay even after I clear them?
This edits only the standard Info dictionary. Some PDFs also store metadata in an XMP packet, which is not changed here, so a separate viewer may still show those values.
