Edit PDF Metadata Online for Free

PDF metadata includes the title, author, subject, and keywords stored inside the document’s properties. This information shows up in browser tabs when viewing the PDF, in file manager columns, in search results, and in document management systems. Our tool reads the current metadata values from your file, lets you edit each field, and saves the updated document with your changes while keeping all visible content untouched.

The editing happens through pdf-lib’s document info API. The library reads the existing PDF info dictionary, presents the current values for editing, and writes the modified values back when you save. Because only the metadata fields change (not the page content), the output file is essentially the same size as the input. The process takes under a second for any file size.

Situations where metadata editing makes a real difference:

• Cleaning up auto-generated metadata (like ’Document1’ or ’Microsoft Word’) before client delivery
• Removing the original author’s name from confidential documents before external sharing
• Adding clear titles and keywords to scanned documents that have blank metadata
• Correcting wrong author names on collaborative documents where the creator field stuck
• Optimizing PDF metadata for search engines when hosting documents on a website

Most people never think about PDF metadata until they send a document with embarrassing properties. A ’Final_Draft_v17_BACKUP_Johns_copy’ title visible in the recipient’s PDF viewer does not look professional. Spending 10 seconds to set a clean title and correct author prevents that entirely.

Metadata editing fits naturally into a document preparation workflow. After merging multiple files, the merged document inherits metadata from the first source file, which usually needs updating. Before sharing externally, combine metadata cleanup with compression and password protection for a polished, secure final document.
