What is PDF Metadata?

PDF metadata tags are document properties embedded inside the PDF file container (usually in the Info dictionary block). These properties include Title, Author, Subject, Creator, Producer, Keywords, and dates. Correct metadata is crucial for search engine indexing of PDFs, catalog filing, and document indexing systems.

With SmartPDFs Pro, your editing is executed 100% locally in your web browser using native JavaScript libraries. Your files never touch our servers, guaranteeing complete document privacy and instant offline tag execution.

Frequently Asked Questions

Is the metadata editor secure?

Yes, absolutely. Unlike other online tools that upload your files to external servers, our PDF metadata editor performs the entire process 100% locally in your web browser. Your private documents never leave your computer.

Which metadata fields can I edit?

You can modify Title, Author, Subject, Keywords, Creator (software used to make the PDF), Producer (engine used to compile), and document creation/modification dates.

Will editing metadata change my original PDF text or layout formatting?

No. Metadata is saved in a separate document info dictionary block at the end of the file structure. Your page text, fonts, and inline graphics remain untouched.

Is there a page or size limit?

Because all processing happens client-side in your browser, there is no server-imposed upload limit. It depends only on your local system's memory and CPU.
