PDF metadata is the descriptive information stored with a document rather than printed on its pages. Clean properties make a file easier to identify in a reader, digital library, archive, or document search. This editor shows the current values before you change them, highlights edits, and lets you blank individual fields. It writes the result to a new download, leaving your source PDF untouched.
The editor targets the PDF's standard document information fields. Some publishing and archival PDFs also contain a separate XMP metadata stream. When the tool detects one, it shows a warning because different PDF readers can prefer different metadata records.
