About PDF Metadata Editor
PDF Metadata Editor is a high-performance web utility built to read and edit PDF document metadata — Title, Author, Subject, Keywords, Creator — directly in your browser. 100% client-side, no file uploads required instantly and securely. Because it is designed with a local-first architecture, all processing occurs directly in your browser's memory using client-side JavaScript. This ensures that your files, code, or private text inputs are never uploaded to any external server or tracked by third-party analytics.
Whether you are formatting source code, cleaning text files, converting file structures, or running diagnostics, running these processes locally in your browser memory sandbox eliminates network latency and protects your data privacy.
Frequently Asked Questions (FAQs)
What metadata can I edit in a PDF file?
You can edit the Title, Author, Subject, Keywords, Creator, and Producer fields of a PDF document. These fields are part of the standard PDF specification and are indexed by search engines, document management systems, and operating system search features.
Is my PDF file uploaded to a server when I edit metadata?
No. The PDF Metadata Editor operates entirely inside your browser using client-side JavaScript. Your document never leaves your device and is never transmitted over the internet.
Will editing the metadata change the visual content of my PDF?
No. Metadata editing only modifies the document information fields (like Title, Author, and Subject) stored in the PDF header. Your text, images, and all page content remain completely unchanged.
Can I remove or clear PDF metadata?
Yes. You can clear any metadata field by leaving it empty and saving. This is useful for removing authorship or creator information from documents before sharing.
What PDF library is used to edit metadata?
The tool uses pdf-lib, a widely-trusted open-source JavaScript library, to read and write PDF metadata entirely within the browser environment.
