PDF Metadata Editor

PDF metadata editing serves two primary purposes: privacy protection before document sharing, and organization improvement for document management. Privacy use cases include removing or replacing the Author field that contains a personal name or username, deleting Creation Date information that reveals when a confidential document was first drafted, removing Creator information that reveals internal tools or software licenses, and cleaning Keywords fields that may contain internal project names or classification codes. Organization use cases include adding descriptive titles to untitled scanned documents, adding author attribution to documents missing proper credit, setting accurate creation dates for documents migrated from other systems, and adding searchable keywords to improve document retrieval in management systems. The AllTools PDF Metadata Editor modifies all standard PDF metadata fields using pdf-lib.js in the browser. The original document is never modified — a new PDF with updated metadata is generated and downloaded. Your document content and metadata stay entirely on your device.

Professional PDF metadata follows established standards that make documents more discoverable and manageable in enterprise workflows. The Dublin Core metadata standard, supported in PDF's XMP metadata format, defines fields like title, creator, subject, description, publisher, date, and rights. Following these standards ensures your PDFs work well with document management systems, digital libraries, and content repositories. Title should be the full document name as you'd want it to appear in a document list — not the filename. Author should be the creating person or organization for attribution purposes. Subject should be a brief one-sentence description of the document content. Keywords should be comma-separated terms that describe the document's topics, useful for search and categorization. The Producer and Creator fields, set automatically by PDF creation tools, often reveal internal software details and can be cleaned for externally shared documents. For archival documents, setting accurate Creation and Modification dates helps maintain accurate document history in records management systems.
