What is PDF Metadata?
Every PDF contains hidden metadata β information about the file itself. Common fields include: Title, Author, Subject, Keywords, Creator (the software that made it), Producer (the tool that converted it to PDF), CreationDate, and ModDate. This metadata is invisible when reading the PDF but can be viewed in file properties or extracted programmatically. It's often used by search engines, document management systems, and readers to categorize and find documents.
Why View PDF Metadata?
Metadata can reveal private information. If you share a PDF created from a Word document, the PDF may contain the original author's name, company, software used, and even file paths. Journalists, lawyers, and security researchers routinely inspect PDF metadata before publishing. Businesses use it to verify document authenticity. Users check it to ensure documents don't leak personal info.
Why Edit PDF Metadata?
Setting a proper title makes documents easier to find in file explorers and search. Adding keywords improves searchability in document management systems. Removing personal info before sharing (like your full name or company) protects privacy. Cleaning up metadata when merging or organizing documents makes the result professional. For SEO-conscious businesses, PDF metadata influences how the file appears in Google search.
Why Use Our Tool?
Most PDF metadata tools upload your files to their servers. For confidential documents, that's a privacy risk. Our tool reads and writes metadata entirely in your browser using pdf-lib. Nothing is uploaded. You see everything instantly and can clear or modify any field before downloading.
