PDF Metadata Editor

The PDF Metadata Editor lets you read and rewrite the information that lives inside a PDF’s document properties: its title, author, subject, keywords, creator, and producer.

Drop in a file, the current values load straight into the form, you edit what you like, and download a new copy with the updated properties.

That hidden metadata is what shows up in a PDF reader’s title bar, in search results, and in document-management systems, so getting it right matters more than it looks.

Maybe a generated report carries the name of the template it came from, an export lists the wrong author, or a file needs proper keywords so it surfaces when colleagues search a shared drive.

This tool fixes all of that without re-exporting from the original application.

Keywords are entered as a simple comma-separated list and are de-duplicated for you; every other field is a plain text box.

The modification date is refreshed automatically when you save.

Everything runs locally with pdf-lib inside your browser, so the document never touches a server — important for anything sensitive — and it keeps working offline once the page has loaded.

The page content itself is left completely untouched; only the document-information dictionary changes, and you always receive a fresh file rather than overwriting your original.
