Quick Answer

Edit Metadata lets you view and change the hidden information embedded in your PDF—author name, document title, creation software, and more. Upload your file, see what's there, modify what you want, and download. Processing happens locally in your browser.

What Is PDF Metadata?

Every PDF carries hidden information that most people never see. This metadata travels with your document wherever it goes—even when you don't want it to.

It's like an invisible ID card attached to every file.

Metadata includes things like who created the document, when it was made, what software was used, the document title, keywords for searching, and more. This information is embedded in the file itself, not visible on any page, but accessible to anyone who knows where to look.

What Metadata Contains

PDF metadata typically includes: Title (document name), Author (creator's name), Subject (topic description), Keywords (searchable terms), Creator (application that made the original), Producer (application that made the PDF), and dates (creation and modification timestamps).

What Metadata Reveals About You

Here's the problem: metadata often reveals more than you intend to share.

👁️ What Your PDF Might Be Exposing

Your full name — The author field often contains your registered software username
Your company — Organization names embedded by enterprise software
Software you use — "Created with Microsoft Word" or "Adobe InDesign CC 2024"
Your computer name — Sometimes embedded in creator/producer fields
When you worked on it — Creation and modification timestamps
Previous authors — Names of people who edited the document before you

📋 Real Scenario: The Anonymous Report

You're submitting an anonymous complaint or whistleblower report. You've been careful not to include your name anywhere in the document. But the PDF metadata shows "John Smith" as the author, "Acme Corporation" as the company, and "Microsoft Word for Mac" as the creator. Your "anonymous" report isn't anonymous at all.

This is why metadata control matters.

Whether you're sharing documents publicly, distributing templates, or just want control over what information travels with your files, understanding and editing metadata gives you that control.

🛡️ Privacy Control for Document Sharing

Before sharing PDFs externally, review and clean metadata to control what information you're distributing:

Public documents: Remove personal author names and company identifiers
Templates: Clear creator information so recipients don't see your details
Sensitive reports: Ensure no identifying information travels with the file
Client deliverables: Set professional titles and appropriate authorship

All editing happens locally in your browser—your document and its metadata never leave your device.

Metadata Fields Explained

The tool lets you view and edit all standard PDF metadata fields.

Title

Example: "Q3 2024 Financial Report"

The document's official name. Shows in PDF readers' title bars and search results. Different from the filename.

Author

Example: "Sarah Johnson"

The person or entity who created the document. Often auto-filled from your software's user settings.

Subject

Example: "Quarterly financial analysis"

A brief description of the document's topic or purpose. Useful for document management systems.

Keywords

Example: "finance, Q3, revenue, analysis"

Searchable terms that help locate the document. Separate multiple keywords with commas.

Creator

Example: "Microsoft Word 2024"

The application that created the original document (before it became a PDF).

Producer

Example: "Adobe PDF Library 15.0"

The software that produced the PDF file itself. Often reveals the conversion tool used.

💡

Leave fields empty to preserve existing values. The tool only updates fields you explicitly change. If you want to modify the author but keep the existing title, just leave the title field blank—it won't be erased.

When to Edit Metadata

Metadata editing serves different purposes depending on your situation.

Situation	What to Do	Why
Public sharing	Clear author, creator, producer	Remove personal/company identification
Professional delivery	Set proper title, author, subject	Professional presentation in document managers
Template distribution	Clear all personal fields	Recipients shouldn't see your info
Document archiving	Add keywords, subject, proper title	Improve searchability in archives
eBook publishing	Set title, author, keywords	Discoverability and proper attribution
Legal documents	Verify/set accurate author info	Proper attribution and audit trails

⚠️ Metadata Isn't the Only Hidden Data

Metadata is just one type of hidden information. PDFs can also contain comments, tracked changes, hidden layers, and embedded files. For sensitive documents, use Flatten PDF to merge all layers and remove interactive elements, and Redact Text to permanently remove visible content.

Frequently Asked Questions

Will editing metadata change my document content?

No. Metadata is separate from document content. Editing metadata changes only the hidden information fields—your pages, text, and images remain exactly the same.

How do I completely remove a field?

Enter a single space or clear the field and the tool will remove that metadata. Leaving a field completely empty preserves the existing value, so to clear a field, you need to explicitly set it to empty/blank.

Can anyone see my PDF's metadata?

Yes. Anyone with the PDF can view its metadata using free tools, PDF readers' document properties, or even command-line utilities. It's not hidden from view—just not displayed on the pages themselves.

What about creation and modification dates?

This tool focuses on the core metadata fields (title, author, subject, keywords, creator, producer). Dates are typically set automatically by PDF software and may be updated when the file is modified.

Is Edit Metadata free?

Yes. Guest users get 2 free uses per day. Free accounts (email signup, no credit card) get 5 daily. Pro subscribers get unlimited access to all 18 PDF tools.

Is my file sent to a server?

No. All processing happens locally in your browser. Your document and its metadata never leave your device. We can't see what you're editing because the data never reaches us.

Does this remove all hidden data from my PDF?

This tool edits standard metadata fields. PDFs can contain other hidden data like comments, form data, hidden layers, and embedded files. For comprehensive cleaning, also consider Flatten PDF and Redact Text.

Why would I add metadata instead of removing it?

Proper metadata improves organization and discoverability. For eBooks, publications, and archived documents, good metadata (title, author, keywords) helps people find and identify your content. It's about control—removing what shouldn't be there, adding what should.
