    FAQ

    Frequently asked questions

    Is my PDF uploaded anywhere when I edit its metadata?

    No, it's entirely local via pdf-lib. Your file never leaves your device.

    Which fields can I edit?

    Title, Author, Subject, and Keywords — the most commonly used PDF document metadata fields.

    Can I clear a field entirely?

    Yes, just empty the text box before saving — an empty field is written as blank/removed metadata.

    Will this change how the PDF looks?

    No, only the invisible document metadata changes — the page content is untouched.
