Edit PDF Metadata

What is Edit PDF Metadata?

Edit PDF Metadata is a free, browser-based tool for reading and rewriting the document information stored inside a PDF. When you load a file it fills the Title, Author, Subject, Keywords, Creation date and Modification date fields with the values already in the document, then lets you correct or replace them and download a new copy. It is handy for fixing a wrong title that shows in a viewer's tab, crediting the right author, adding searchable keywords, or wiping personal details before sharing a file. People who publish reports, send invoices, or archive scanned documents reach for it most, since clean, accurate metadata makes files easier to find and looks more professional.

How to use Edit PDF Metadata

1. Drag and drop a PDF onto the dropzone (or click to choose a file). The tool loads it, shows the page count and a first-page preview, and fills the fields with the document's existing metadata.
2. Edit any field: Title, Author, Subject, Keywords (comma-separated), and the Creation and Modification dates.
3. To wipe everything instead of editing, open Settings and tick "Remove all metadata" — the input fields are ignored and all properties are cleared.
4. Click "Apply & download" to build a new PDF with your changes and save it. The original file is left untouched.
5. Use Reset to clear the file and start over with a different PDF.

Frequently asked questions

Is my PDF uploaded to a server?

No. Everything runs 100% client-side in your browser using pdf-lib. The document is read and rewritten locally and is never uploaded, so even confidential files stay private.

Which metadata fields can I change?

Title, Author, Subject, Keywords, Creation date and Modification date. When you enable "Remove all metadata" the tool also clears the Creator and Producer fields for a clean copy.

How do I enter keywords?

Type them in the Keywords field separated by commas, for example "invoice, 2026, report". Each comma-separated term is stored as its own keyword, and blank entries are skipped.

Does editing change the pages or content?

No. Only the document's information dictionary (its properties) is updated. The pages, text and images are copied through unchanged.

What happens to the dates when I remove all metadata?

Removing all metadata clears the text properties (title, author, subject, keywords, creator, producer). The creation and modification dates are left as they are, since a meaningful date can't be invented from nothing.
