About the Edit PDF Metadata Tool

Every PDF file carries a set of hidden properties — title, author, subject, keywords, creator, and producer — that describe the document without appearing on any page. ChopFile's metadata editor lets you view and change all of these fields instantly, entirely in your browser, without uploading anything.

How it works

When you drop in a PDF, ChopFile uses the open-source pdf-lib library running directly in your browser to read the existing metadata and populate the form. After you make your edits and click Save & Download, pdf-lib writes the updated properties into a new copy of the document and downloads it to your device. Nothing is ever sent to a server — your file stays private from start to finish.

When to use Edit PDF Metadata

Tips for best results

Load the file first and review what's already embedded — you may find a previous author's name or an internal draft title you didn't know was there. Use the Keywords field to add comma-separated terms that describe the document's content. If the PDF is password-protected, run it through Unlock PDF first. After editing, you can further refine the document by reordering pages with PDF Page Organizer, combining it with other files using Merge PDF, or breaking it into sections with Split PDF.
