What PDF metadata is
Besides its pages, every PDF can carry a small set of descriptive fields: a title, an author, a subject, keywords, the application that created it and the producer that generated the file. Many PDFs also include XMP metadata, a more detailed block of the same kind of information. You rarely see these fields, but they travel with the file wherever it goes.
They are filled in automatically by the program that made the PDF, which is why they are often wrong, empty or more revealing than you expect. This tool shows you what is there and lets you change it.
Make the title look right
When you open a PDF in a browser or many readers, the window or tab shows the document title from the metadata, not the file name. If the title field says something like “Microsoft Word - draft_v3_final” or an old project name, that is what your readers will see. Setting a proper title, such as “2026 Annual Report” or your full name and “Résumé”, gives the file a professional finish.
Subject and keywords describe the content. Some document management systems, libraries and search tools read them, so filling them in can help people find the file later.
Don’t leave your username behind
The author field is often filled with the account name of the computer that created the document. That can be your personal name, a nickname, or a login from an old job. Before you send a file to a client, publish it on a website or submit it to an employer, you may prefer that it doesn’t carry that detail.
You can edit the author field, or remove all metadata at once, including the XMP block. The content of the pages doesn’t change at all: the text, images and layout stay exactly as they were. If the pages themselves hold information you need to hide, use Redact PDF instead.
Everyday uses
A freelancer sends proposals built from an old template and fixes the title and author on each one. A school publishes forms on its website and gives each PDF a clear title so the browser tab reads well. An office cleans the metadata from documents before they go to an outside party. A writer adds keywords to an ebook-style PDF so it is easier to catalog.
It is also a quick way to simply look: open a PDF you received and check which program produced it or who is listed as its author, without changing anything else.
