Upload any PDF to inspect its Title, Author, Subject, Keywords, Creator, and Producer fields. Edit any field, then download the updated file. All processing is done locally using pdf-lib. Nothing is sent to a server.
What is PDF metadata?
PDF files store document information in a standard dictionary called the Document Information Dictionary. Fields like Title and Author appear in the title bar of PDF readers, in print dialogs, and in search engine previews when the PDF is publicly accessible.
Why edit PDF metadata?
Common reasons to update PDF properties include: correcting an auto-generated title, removing an author name before sharing, adding keywords for better search discovery, or stripping creator/producer strings to reduce fingerprinting. Editing metadata does not change any visible content in the document.
Privacy
Your file is processed entirely in your browser. No data is transmitted to any server. Closing the tab leaves no trace of the document.
Metadata fields reference
| Field | Purpose | Notes |
|---|---|---|
| Title | Document title displayed in PDF viewer title bar and browser tabs | Often auto-generated from the filename; frequently wrong |
| Author | Person or organization who created the content | Remove before sharing externally to avoid revealing author identity |
| Subject | Topic or theme of the document | Used by some search engines for indexing PDFs |
| Keywords | Comma-separated tags for search and categorization | Helps PDF search in document management systems |
| Creator | Application that originally created the document | E.g., "Microsoft Word 2021" or "Adobe InDesign 2024" |
| Producer | PDF rendering software that converted to PDF format | E.g., "Adobe PDF Library 21.0" or "pdfTeX 1.40" |
| Creation Date | When the document was originally created | ISO 8601 format stored in the PDF; shown in viewer Properties dialog |
| Modification Date | When the document was last modified | Updated automatically by PDF editing tools |
Removing metadata entirely
This tool lets you edit individual metadata fields - changing values or clearing them to empty strings. If your goal is complete metadata removal for privacy, you have two options:
- Clear all fields: set every field to an empty string using this tool, then save. This removes standard Document Information Dictionary entries.
- Full metadata strip (including XMP): PDFs also contain an XMP (Extensible Metadata
Platform) packet that stores the same information in XML format. Tools like ExifTool (
exiftool -all= document.pdf) or Ghostscript remove both the Document Information Dictionary and the XMP packet for thorough metadata removal.
