Upload a PDF to view and edit its metadata — title, author, subject, keywords, creator, and producer. Download the updated PDF. No upload to any server.
Drop a PDF in the panel on the left to load its existing title, author, subject, keywords, creator, and producer here. Edit any field, then hit Save & Download to grab an updated copy — your original file is never touched and nothing leaves your browser.
Every PDF carries a small set of document properties — title, author, subject, keywords, creator, and producer — stored in its information dictionary. This tool reads those values straight from your file and lets you change, add, or clear any of them, then hands back a fresh copy with the updated properties baked in.
Metadata is invisible on the page but it drives how your document is labelled in file browsers, search results, and document management systems. People use it to:
Everything runs 100% in-browser using pdf-lib; nothing is uploaded to any server, so even confidential files stay on your own machine.
PDF metadata is a set of document properties stored inside the file's information dictionary — title, author, subject, keywords, creator, and producer. It describes the document but does not appear on any printed page.
The title is what shows in browser tabs and search results, the author credits who wrote it, and keywords help people find the file. Setting them correctly makes a PDF look professional and easy to locate instead of just a raw filename.
Yes. Search engines and document management systems read PDF metadata when indexing files, so a clear title, subject, and relevant keywords can improve how and where your PDF surfaces in search results and internal search.
Open the PDF, delete the text in any fields you want to remove — such as author, creator, or producer — and click Save & Download. The downloaded copy will have those properties blanked out.
No. Only the document information dictionary is updated. Page content, images, fonts, and layout stay exactly as they were.
This tool focuses on the text properties — title, author, subject, keywords, creator, and producer. The creation and modification dates are managed by pdf-lib when it saves the file and are not exposed as editable fields here.
No. pdf-lib runs entirely in your browser, so the file is read and rewritten locally and nothing is ever sent to a server.
