How to View, Edit, and Remove PDF Metadata

Every PDF carries information you don't see on its pages: a title, the author's name, a subject and keywords, the app it was created in, the software that produced the PDF, and when it was created and last changed. This metadata decides what appears in a browser tab or a viewer's title bar, helps search engines and document systems index the file, and — often without anyone noticing — reveals who made a document and with what tools. PDFDoco lets you inspect it, correct it, or remove it entirely, right in your browser.

One-tap privacy clean

Remove author names, software versions, and dates from the file's properties in one step.

Nothing is uploaded

Metadata is read and rewritten in your browser, so the document never leaves your device.

What each field means

Title is the document's display name, shown by many viewers instead of the file name. Author is the person or organisation credited. Subject is a short description, and Keywords are search terms. Creator names the app the original was made in, such as a word processor, while Producer names the software that converted it to PDF.

Why metadata matters for privacy

Office apps fill in the author field automatically from your account, so a document shared outside your organisation may carry your full name, a colleague's name, or an old template owner. Creator and producer fields can reveal the exact software and version you use, and dates can show when a document was really drafted. Many PDFs also hold a second copy of these details in an XMP metadata packet that ordinary property dialogs don't show. Remove all metadata clears both.

Metadata for search and organisation

A descriptive title and a few accurate keywords make a PDF easier to find in a document management system, a shared drive, or a website. When a PDF is published online, search engines may show its title in results, so a clear title like "2026 Product Catalog" reads much better than "Microsoft Word - Document1". Keep keywords short and relevant.

What changes when you save

Only the document properties are rewritten. Fields you leave empty are removed rather than saved blank, the modification date is set to the time you save, and the creation date is kept. Older embedded metadata copies are cleared so they can't contradict your new values. Pages, text, images, bookmarks, links, and form fields are left untouched.

Pro tip: sharing a document outside your organisation? Remove all metadata as the very last step, after any other edits, so no tool adds new details back in afterwards.

Frequently Asked Questions

What is PDF metadata?

Metadata is information stored inside the PDF about the document itself rather than on its pages: the title, author, subject, keywords, the app that created it, the software that produced the PDF, and when it was created and last modified. PDF viewers show it in the document properties, and search engines and document systems use it for indexing.

Why does the title in my PDF viewer look wrong?

Many viewers and browser tabs display the metadata title instead of the file name. If a PDF was exported from a template, the title may still say something like "Untitled" or an old project name. Set the Title field here to fix it.

What does "Remove all metadata" remove?

It clears every document property — title, author, subject, keywords, creator app, producer, and both dates — and deletes embedded XMP metadata packets, which often hold another copy of the author name and software details. Page content, bookmarks, links, and form fields are not touched.

Does removing metadata make a PDF anonymous?

It removes the document properties, which is where names and software details usually hide. But the pages themselves can still contain identifying information, such as names in headers, signatures, comments, or text in images. Review the visible content too before sharing a document anonymously.

Why are the dates not editable?

The creation date is kept as it is, and the modification date is set to the moment you save, which is what PDF readers expect. Removing all metadata clears both dates.

Will editing metadata change my document's pages?

No. Only the document properties are rewritten. Text, images, fonts, and layout stay exactly the same, and the file size changes only slightly.
