How do I change the author of a PDF?

Drop the PDF, type a new value into the Author field, and click Save. The downloaded PDF will show the new author name in any reader's File > Properties view.

Can I leave some fields unchanged and only edit one?

Yes. The form prefills with the current values. Anything you do not modify stays as it was. Clearing a field and saving removes that field from the PDF.

What is the difference between Creator and Producer?

Creator is the application the document was authored in (for example, a word processor or design tool). Producer is the library or driver that actually wrote the PDF bytes. Both fields are editable.

Are the date fields editable?

Yes. Pick a new date for CreationDate or ModificationDate, or clear them to remove them. A date you do not touch keeps its original value, including the time of day. PDF readers show no timestamp for a removed date.

Is my PDF uploaded anywhere when I save?

All editing and saving happens in your browser using pdf-lib. The new PDF is generated locally and downloaded straight to your device.

Edit PDF Author and Title

Update any metadata field stored in a PDF: rewrite the author, change the title, add keywords, or clear individual fields you do not want to publish. The tool shows current values prefilled in a form so you can edit and save. All processing runs in your browser.

How it works

pdf-lib reads the existing Document Information Dictionary and prefills each field in the form; a value stored in a format it cannot read is named under the form instead and kept unless you enter a new one or clear every field. When you press Save, the tool writes only the fields you changed and removes the ones you cleared (it never writes an empty value or a 1970 date). Keywords are written exactly as you typed them. It also removes the XMP copy of these fields, because some readers, such as Firefox's viewer, show XMP values first and would keep showing the old ones. Custom properties and comment authors are kept. With every field blank, Save instead removes all document properties, as Strip all metadata does. The updated bytes download as a new PDF.

Processing runs in your browser

All processing happens inside your browser tab. pdf-lib handles everything in memory; our servers are not involved at any point. You can verify this yourself in your browser's DevTools Network tab.
