PDF Metadata Editor

What this tool does

PDF Metadata Editor reads the document information of a PDF and lets you change or remove each field, including creation and modification dates. It can also delete the XMP metadata stream so old values do not linger, and shows the PDF version and page size.

Every PDF carries a small set of properties alongside its pages. The Title appears in browser tabs and search results, Author often holds the login name of whoever created the file, and Creator and Producer reveal the software used. Exported files frequently have a meaningless title such as "Microsoft Word - Document1.docx" or personal names you would rather not share.

This editor reads the PDF document information dictionary with pdf-lib, shows each field in a form, and writes your changes back without touching the page content. Clearing a field removes it from the file. Many PDFs also contain an XMP metadata stream, a second XML copy of the same details, which the tool can remove so viewers cannot fall back to stale values. Nothing is uploaded.

How to use PDF Metadata Editor

1. Drop a PDF onto the upload area. The current values and a Document facts table appear.
2. Edit Title, Author, Subject and Keywords. Separate keywords with commas.
3. Change Creator and Producer if you want to hide or correct the software names.
4. Set or clear the Created and Modified dates using the date and time pickers.
5. Leave Remove XMP metadata stream switched on unless you need the XMP data.
6. Press Save PDF and download the updated file.

Tips for better results

• Use Clear all fields and then Save to produce a file with no identifying document information.
• A descriptive Title, such as "Annual Report 2026 - Acme Ltd", improves how the file appears when opened in a browser or indexed by search engines.
• Revert restores the values that were in the file when you opened it.
• The changed-fields counter helps confirm you edited what you intended before saving.

Common use cases

• Removing your name and company from a PDF before posting it publicly.
• Giving exported reports a proper title instead of the original file name.
• Adding keywords to PDFs in a document management system to make them easier to find.
• Correcting the creation date on a scanned archive document.

Common mistakes to avoid

• Assuming metadata is the only hidden information. Comments, form data and text hidden under images are separate and are not cleaned by this tool.
• Leaving the XMP stream in place after editing, so some viewers still show the old author.
• Expecting the file name to change. Metadata Title and the file name are independent.
