Edit PDF metadata

How to Edit PDF metadata

1

Add your PDF

Click “Select file” or drag and drop a PDF. The current metadata (title, author, subject, keywords, creation date) is displayed.

2

Edit the fields

Update any of the metadata fields: title, author, subject, keywords, and creation/modification dates. Leave fields blank to clear them.

3

Save and download

Click “Save Metadata”. The updated file saves to your Downloads. The original file is unchanged.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

DukPdf’s Edit Metadata tool changes the title, author, subject, keywords, and creation date of a PDF — in your browser. Metadata is the hidden information that appears in the PDF reader’s “Properties” panel. All editing runs locally — your file never leaves your device. To merge the metadata-cleaned file with other PDFs, use Merge PDF. For a step-by-step guide, see our metadata guide.

When you'd use this

Set a clean document title

Replace the default filename (e.g., “document1234.pdf”) with a proper title that shows up in the PDF reader and search results.

Add author information

Set the author field to your name or organization so readers know who created the document.

Add keywords for searchability

Add relevant keywords so the PDF is easier to find in document management systems and search tools.

Strip metadata for privacy

Remove the original author name, creation date, and editing history from a PDF before sharing it externally. Metadata can leak who worked on the document and when.

Edit Metadata — questions

Why does metadata matter for privacy?

PDF metadata can reveal the original author name, the organization that created the document, the software used, and a detailed editing history. Removing this metadata before sharing externally prevents unintended information leaks.

Is the file uploaded during metadata editing?

No. Metadata editing runs entirely in your browser. Open DevTools → Network tab — zero upload requests.

What metadata fields can I edit?

Title, author, subject, keywords, creator (application), producer (PDF generator), creation date, and modification date. You can set any field, clear any field, or leave it unchanged.

Can I edit metadata in batch?

The current tool edits one file at a time. If you have many files to update, run the tool on each one separately. Each file’s metadata can be different.

Will editing metadata change the visible content?

No. Metadata editing only changes the hidden “Properties” information. The visible pages, text, images, and layout are completely unchanged.

Can I remove all metadata at once?

Yes. Click the “Clear All” button to remove all metadata fields. The result is a PDF with no title, author, subject, keywords, or dates — fully anonymous.
