PDF Toolkit

Edit PDF Metadata

Modify the Title, Author, Keywords, and invisible structural values of your document.

About This Tool

Every PDF file contains hidden structural information called metadata, which dictates how search engines index the file and what properties display when someone opens it. PDF Toolkit's free Edit Metadata tool lets you view and directly manipulate these hidden properties. You can easily alter the document's Title, Author, Subject, Keywords, Creator, and Producer values to improve the file's SEO visibility or to redact personal information before publishing it online. Because this tool runs completely on your local device via the browser using WebAssembly technology, your sensitive corporate or personal documents are never transmitted across the web. The metadata extraction and saving processes are instantaneous, allowing you to quickly scrub and update files with enterprise-grade privacy.

    Click "Save Metadata & Download" to generate a new PDF containing your updated properties.


Frequently Asked Questions

Why should I edit PDF metadata?+
Editing metadata can improve how your document is indexed by search engines. Alternatively, removing metadata (like the author name) protects your privacy before sharing.
Is my document contents altered during this process?+
No. The visual contents (text, images, layout) of your PDF remain completely untouched. Only the background dictionary properties are updated.
Who can see PDF metadata?+
Anyone who downloads the PDF can view its metadata. In most PDF viewers (like Adobe Acrobat or Chrome), they simply need to right-click and select "Document Properties".
Does this tool work locally?+
Yes! The extraction and saving of the metadata occur entirely within your web browser. No files are uploaded to our servers.
