How to Edit PDF Metadata: Change Title, Author, Subject & Keywords
Learn how to view and edit PDF metadata online. Free PDF metadata editor that works entirely in your browser.
Every single PDF file floating around the internet contains a hidden layer of information called Metadata. This invisible data defines the document’s true Title, Author, Subject, and SEO Keywords.
While average users never look at metadata, search engines (like Google), enterprise document management systems, and desktop search tools rely heavily on it to properly index and organize files.
🚨 The Danger of Incorrect Metadata
Have you ever opened a beautifully designed corporate PDF, only to look at the top of your web browser tab and see the title is “Microsoft Word - Document1_final_V4_Copy.docx”?
This happens because the person who exported the PDF completely forgot to clean the metadata. It is incredibly unprofessional and immediately breaks the illusion of a polished document.
🏷️ The 4 Core Metadata Fields Explained
When you use a Metadata Editor, you are interacting with these specific tags:
| Metadata Field | What it Actually Does | Good Professional Example |
|---|---|---|
| Title | The official name displayed at the top of PDF viewers and browser tabs. | “Q3 Financial Earnings Report” |
| Author | The person or organization legally credited for creating the document. | “Jane Doe, Acme Corporation” |
| Subject | A brief, descriptive summary of the document’s contents. | “Detailed analysis of Q3 2026 financial revenue and losses.” |
| Keywords | Comma-separated SEO tags for enterprise search engines. | “finance, quarterly, earnings, Q3, 2026” |
🧹 Why You Should Edit (Or Purge) Metadata
- Maximum Professionalism: Ensure your client-facing documents have clean, official titles rather than messy file-export names.
- Enterprise Searchability: Adding specific keywords guarantees your document will appear correctly when your boss searches the company intranet.
- Privacy Compliance (Sanitization): Sometimes you want to delete metadata. If you are submitting an anonymous manuscript or a legal whistle-blower document, you must aggressively purge the “Author” field to protect your identity!
