FAQ

Common questions

Does this change the PDF's actual content?
No — only the document properties (title, author, subject, keywords) change. Every page is copied through unchanged.
Is my file uploaded anywhere?
No. Reading and rewriting the metadata both happen entirely in your browser — nothing is transmitted, logged, or stored.
Why rebuild the whole document instead of editing it in place?
Copying every page into a fresh document avoids carrying over any corruption or inconsistency in the original file's internal structure, so the output is always clean.

PDF Metadata Editor

Every PDF file contains hidden information called metadata. This includes the title, author, subject, and keywords. This tool allows you to view and modify this data easily.

How to Edit PDF Metadata

1. Upload PDF

Drop your PDF file into the upload box.

2. View Current Metadata

The tool will extract and display the current:

  • Title
  • Author
  • Subject
  • Keywords

3. Edit and Save

  • Type your new values into the fields.
  • Click "Update PDF Metadata".
  • Your new PDF with the updated information will be downloaded automatically.

Why Edit Metadata?

  • SEO: Search engines read PDF metadata. A good title and keywords help your document get found.
  • Organization: helps citation software (like Zotero or EndNote) correctly identify your document.
  • Professionalism: Ensure the "Author" field shows your name or organization, not "Microsoft Word" or "Administrator".
  • Privacy: Remove sensitive information from the metadata fields before sharing.

Technical Details

  • Client-Side Processing: Your PDF is processed entirely in your browser using pdf-lib. It is never uploaded to our servers, ensuring your document remains private.
  • Fast: Metadata editing is lightweight and happens almost instantly.
