PDF Metadata Editor

Replace an automatic title taken from a file name or a draft, correct the author when a document was created from someone else's template, add a subject and keywords before filing a document in a management system, set the language before publishing an accessible PDF, and make sure reports, white papers and brochures look professional when people open them in their browser.

These are the standard document properties of a PDF. Leave a field empty to remove it from the file.

Modern PDFs often store their properties twice: in the classic document information dictionary and in an XMP metadata stream. Readers such as Adobe Acrobat prefer the XMP copy when it exists. If only the classic properties were changed, those readers would keep showing the old title and author. By default the editor therefore removes the outdated XMP copy, so every reader shows your new values. Turn the option off only if the XMP stream contains information you need to keep, such as rights statements from a publishing workflow.

For PDFs published on a website, the title property often appears as the headline in search results and as the browser tab label, so a clear, descriptive title is worth setting — for example Annual Report 2026 – Example Ltd rather than a file name. Setting the language, such as en-GB or de, helps screen readers pronounce the text correctly and is required by accessibility standards such as PDF/UA. Keywords are rarely used by search engines today but help internal document search.

The editor uses pdf-lib, an open-source library, to change only the metadata; page content, fonts, images, links and form fields stay exactly as they were. Everything happens on your device. Encrypted PDFs must be unlocked first with Unlock PDF. To remove all properties at once before sharing a document, use the PDF Metadata Remover instead.
