How to Edit PDF Metadata (Title, Author, Keywords) — Free

Open the “Properties” panel on almost any PDF and you’ll find a handful of fields you probably never touched: Title, Author, Subject, Keywords, Creator. This is the file’s metadata — information about the document that isn’t part of the visible pages. Most people never think about it, but it quietly affects how your files are named in browser tabs, how they get indexed, and sometimes what they reveal about you. Here’s what it is, why it matters, and how to change it in seconds.

What PDF metadata actually contains

Every PDF carries a small metadata block, whether you set it or not. The common fields are:

• Title — often shown in the browser tab or reader window title, separate from the file name
• Author — who created the document (frequently auto-filled with a real name from Word or Google Docs)
• Subject — a short description of what the document is about
• Keywords — comma-separated terms, sometimes used by document management systems or search
• Creator / Producer — which software generated the file (e.g. “Microsoft Word”, “Adobe Acrobat”)
• Creation date / Modification date — timestamps, often auto-set and rarely accurate to when you actually finished the file

None of these fields appear on the page itself. You only see them by right-clicking → Properties in a desktop reader, or by opening a metadata tool.

Why it matters

Privacy. If you exported a PDF from Word, there’s a good chance the Author field still has your real full name, your company account name, or even a previous employee’s name from a shared template. Before sending a résumé, a legal document, or anything you share externally, it’s worth checking what’s hiding in there.

Professionalism. A generic Title like “Untitled” or “Microsoft Word - Document1” showing up in someone’s browser tab looks sloppy, especially for something like a proposal or a portfolio PDF. Setting a clean, human-readable title fixes that instantly.

Findability. If you host PDFs on a website (product spec sheets, reports, guides), a well-written Title and Subject can help both users and search engines understand what the file is before they even open it.

Consistency. If you batch-export PDFs from a template, they often all inherit the same Author or Creator field from the original software, regardless of who actually created each one. Cleaning that up keeps your files consistent.

How to edit PDF metadata (free, in your browser)

1. Open the Edit PDF Metadata tool.
2. Add your PDF — the tool reads its current metadata and shows you every field.
3. Edit Title, Author, Subject, and Keywords directly. Clear any field you don’t want to keep (like a stale Author name).
4. Download the updated file. The pages themselves are untouched — only the hidden info fields change.

Because it runs entirely in your browser, your document is never uploaded anywhere just to change a text field. That matters more than it sounds: metadata edits are often done right before sending a sensitive document, which is exactly the moment you don’t want to hand a copy to a random online converter.

A quick checklist before sharing a PDF externally

• Title — set something clear and specific, not “Document1” or a random export name
• Author — check it’s actually your name or your organization’s, not a leftover from a template or a former colleague
• Subject / Keywords — optional, but useful if the file will be searched or archived
• Creator / Producer — usually fine to leave; it just names the software used

If the document also contains sensitive content in the pages themselves — not just metadata — go a step further. Metadata editing only touches the hidden fields; it doesn’t restrict who can open or edit the file. For that, use the Protect PDF tool to add a password before sending anything confidential.

Metadata vs. content: know the difference

It’s worth being precise here: metadata editing changes information about the file, not the file’s visible content. If you need to redact a name that appears on the actual pages — in the body text, a header, or an image — metadata editing won’t touch that. You’d need to edit or black out the content itself. Metadata is purely the invisible layer: what shows up in “Properties,” in some search indexes, and in browser tabs.

Keep it private

Metadata can feel like a minor detail, but it’s still information about you or your organization embedded in every file you send. The Edit PDF Metadata tool runs 100% locally — no upload, no account, no size limit — so you can clean up a file’s hidden fields as casually as you’d rename it, without sending it anywhere first.
