Edit PDF Metadata

About Edit PDF Metadata

This tool lets you edit PDF metadata and document properties, or strip them entirely with one-click Remove All Metadata for privacy. You can modify Title, Author, Subject, Keywords, Creator, and Producer. Keywords are stored as a proper comma-separated list and the original CreationDate is preserved. Note: this editor works on the standard PDF Document Information dictionary fields; it does not edit custom or XMP-only properties. All processing happens in your browser for complete privacy.

What metadata can I edit?

You can edit Title, Author, Subject, Keywords, Creator, and Producer fields. These are the standard PDF document information fields.

Will the PDF content change?

No, only the metadata is updated. The actual content, pages, and visual appearance of the PDF remain unchanged.

Why edit PDF metadata?

Metadata helps with document organization, searchability, and professionalism. Proper metadata makes PDFs easier to find and identify in file systems and search engines.

What is the difference between Creator and Producer?

Creator is the application that created the original document. Producer is the software that converted it to PDF. For example, Creator might be Microsoft Word and Producer might be Adobe PDF.

Can I remove metadata?

Yes. Click Remove All Metadata to strip Title, Author, Subject, Keywords, Creator and Producer in a single step. You can also clear individual fields by emptying them and clicking Update Metadata.

How do I scrub metadata before sharing a PDF publicly or legally?

Use the Remove All Metadata (Privacy Sanitize) button. PDFs often carry your name as Author, your software as Creator/Producer, and internal keywords. For legal filings, finance, government or publishing, scrub these identifying fingerprints before external release to avoid data leaks, then use Preview to verify the fields are blank.

What is the difference between the Document Information dictionary and XMP metadata?

The Document Information dictionary holds the classic Title, Author, Subject, Keywords, Creator, Producer and dates that this tool edits. XMP is a newer XML-based metadata stream that can store the same plus custom and application-specific properties. This editor targets the standard Info dictionary; it does not modify custom XMP-only properties.

What is the difference between CreationDate and ModDate?

CreationDate marks when the document was originally created and is important for provenance and audit trails. ModDate (modification date) marks the last change. When you edit metadata here, the original CreationDate is preserved and only ModDate is refreshed to the current time.

Is my PDF file safe?

Absolutely! All metadata editing happens in your browser. Your file is never uploaded to any server.

Can I preview the PDF?

Yes! You can preview the PDF after updating metadata to verify it opens correctly before downloading.

Will file size change?

The file size may change slightly depending on the amount of metadata added or removed, but typically the change is minimal (a few KB).
