How it works
The PDF Metadata Editor lets you read and edit the metadata fields stored in any PDF document: Title, Author, Subject, Keywords, Creator (the application that created it), Producer, and Creation/Modification dates. The edited PDF is exported with updated metadata.
PDF metadata is used by search engines (both web and local), document management systems, and library catalog software to index and retrieve documents. Incorrect metadata (e.g., a title field that still says "Microsoft Word - Document1.docx") looks unprofessional in search results and DMS catalogs. Properly set keywords make documents findable by colleagues searching internal archives.
How to use it: upload your PDF. The current metadata values are displayed in an editable form. Edit any field. Click Save and Download the PDF with updated metadata.
Standard PDF metadata fields: - Title: displayed in browser tabs and PDF viewer title bars - Author: person or organization who authored the content - Subject: a brief description of the document's content - Keywords: comma-separated terms for search indexing - Creator: the application that originally created the document - Producer: the PDF rendering software (usually left as-is)
Privacy metadata: the Author field often contains the name of the person who created the file in Word or Acrobat. The Creator field may reveal internal software or version information. Editing these fields before distributing removes inadvertent personal data exposure.
Privacy: metadata editing runs in the browser using pdf-lib. Your PDF is never uploaded.
Frequently Asked Questions
- No. Metadata is stored in a separate PDF dictionary object and does not affect any page content, images, text, or layout. The output file is visually identical — only the properties panel in PDF viewers and the search index metadata changes.
- Upload the PDF and edit the Author field (and optionally the Creator field if it shows software like 'Microsoft Word'). Save. The output PDF will show your corrected author name in document properties in all PDF viewers.
- Edit the Keywords field and enter comma-separated terms relevant to the document's content. Most DMS platforms (SharePoint, Alfresco, M-Files) index the PDF's Keywords metadata field for full-text search — adding good keywords dramatically improves discoverability.
- Creator is the application that originally authored the content (e.g., 'Microsoft Word 16.0'). Producer is the application that converted it to PDF (e.g., 'Adobe PDF Library 21.0'). Creator is the more meaningful field for document provenance. Both can be edited for privacy or correctness.
