The PDF standard defines a document information dictionary with these fields: Title (document name), Author (person who wrote it), Subject (topic or description), Keywords (search terms), Creator (application that originally created the document), Producer (application that generated the PDF file), CreationDate, and ModDate. All are optional — a PDF can have none, some, or all of them filled.
Common reasons include: fixing incorrect title or author before publishing; removing personally identifying information (author name, creator app) before sharing externally; adding keywords to improve indexing in document management systems; correcting wrong creation or modification dates; and removing auto-generated producer strings like "Acrobat 9.0" from older files.
Page content is untouched. File size may change very slightly (a few bytes) because pdf-lib rewrites the cross-reference table when saving, but pages, images, fonts, and embedded files are identical.
PDFs can store metadata in two places: the classic document information dictionary (what this tool edits) and an XMP stream (an XML format embedded in the PDF). pdf-lib edits the information dictionary. If the PDF also contains XMP metadata, that block is left as-is. Most consumer PDF readers display the information dictionary values, so for typical use cases this tool is sufficient.
If the PDF has an owner password only (which sets permissions but does not prevent opening), this tool can load and edit it. If the PDF has a user (open) password, you will need to remove the password first using the PDF Password Remover, then edit the metadata.
