Edit PDF Metadata
Edit PDF metadata when the standard document properties are missing, incorrect, or reveal an outdated workflow. You can update the title, author, subject, keywords, and creator fields while leaving every field you do not fill in unchanged. The browser writes the selected properties into a new PDF locally; page content is not uploaded or deliberately altered.

Verified behavior and practical limits
Last tested:
How it processes your file
The browser writes only the non-empty title, author, subject, keywords, and creator values you provide into a newly saved PDF.
Verified behavior
- Supports five editable standard metadata fields.
- Fields left empty retain their existing values.
- Visible page content is not deliberately edited.
Important limits
- Producer and timestamp fields are not editable in this form.
- Saving creates a new PDF representation, so byte-for-byte identity is not guaranteed.
Reproducible example workflow
- Input
- A report with an outdated author and missing subject.
- Action
- Enter the correct author and subject, leaving other inputs empty.
- Expected output
- metadata-updated.pdf with those two properties changed.

Frequently asked questions
Where does PDF metadata show up?
PDF viewers and document-management systems may display fields such as title, author, subject, keywords, and creator. The exact fields shown depend on the application.
Can I leave one of the fields empty?
Yes. Only the fields you fill in are updated; empty fields keep their existing values in the downloaded document.
Does editing metadata change the page content?
The editor changes document properties rather than visible page content. Saving creates a new PDF file, so the output is not promised to be byte-for-byte identical.
