About This Tool
PDF files automatically embed invisible metadata tags detailing creator names, computer usernames, software version build numbers, original file paths, and creation timestamps. When publishing research papers, submitting legal briefs, or sharing client proposals, leaving raw internal metadata intact exposes unintended internal information. Our client-side PDF Metadata Editor allows you to view all embedded property headers transparently. You can edit title, author, subject, and keyword fields for improved cataloging, or click 'Strip All Metadata' to sanitize the file before public distribution. Because binary header editing occurs strictly inside local browser memory using JavaScript byte manipulation, no file data ever touches external web servers. Ensure complete document hygiene and privacy in seconds.
