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. When you press Save, the tool calls setTitle, setAuthor, setSubject, setKeywords, setCreator, and setProducer with the new values (or undefined for cleared fields), then writes the updated bytes back as a new PDF for download.
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 yourselfin your browser's DevTools Network tab.

Frequently asked questions
- 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 leave them blank to remove them. PDF readers will then show no creation or modification timestamp.
- Is my PDF uploaded anywhere when I save?
- No. All editing and saving happens in your browser using pdf-lib. The new PDF is generated locally and downloaded straight to your device.
