The metadata fields and what they are for
PDF readers show these fields under Document Properties. Only Title is shown in everyday use, but all of them travel with the file wherever it goes.
| Field | What it holds | Example |
|---|---|---|
| Title | The document name readers can show instead of the file name | Annual Report 2025 |
| Author | The person or team who wrote it | Finance Team |
| Subject | A one-line description | Results for the year ended March 2025 |
| Keywords | Words to help find the file | annual report, results, finance |
| Creator | The app that made the original document | Microsoft Word |
| Producer | The app or library that wrote the PDF | macOS Quartz PDFContext |
| Created and Modified | Dates stored inside the PDF | 2025-05-12 09:30 |
| Language | The main language tag | en-GB |
Checking a PDF before you share it
Metadata can reveal more than people expect: the author's full name, an old employer, the internal file name or the date a draft was really written.
- Open the PDF here and read every field, including custom fields.
- Press Remove all metadata, or keep only a clean title for documents you publish.
- Keep the XMP packet box ticked so no hidden copy of the old values stays behind.
- Remember that names on the pages themselves are not metadata and need editing separately.
Common questions
How do I change the title of a PDF?
Open the PDF here, type the new title and press Save & download. Tick Show the title instead of the file name if you want readers such as Acrobat and Chrome to display it in the tab or window bar.
How do I remove metadata from a PDF?
Open the PDF and press Remove all metadata. The document information dictionary, the XMP packet and the language tag are deleted, and the clean copy downloads with a -clean suffix. The visible pages are not changed.
What metadata does a PDF usually contain?
Most PDFs store a title, the author's name, the app that created the original, such as Microsoft Word, the library that wrote the PDF, and creation and modification dates. Some add keywords, a subject, a company name or file paths in custom fields.
Why does a PDF show an old title after I change it?
Many PDFs keep a second copy of their metadata in an XMP packet, and some readers prefer that copy. Keep Remove the XMP metadata packet ticked when saving, so only your new values remain.
Does PDF metadata matter for search engines?
Search engines can use a PDF's title when they list it, and a title like Microsoft Word - Document1 looks careless in results. Set a clear title and subject before you publish a PDF on your website.
Can I change the creation date of a PDF?
Yes. Pick a new date and time in the Created or Modified field, or clear a field to remove that date. The file's own timestamp on your computer is separate and is set when you save the download.
Does removing PDF metadata remove names printed on the pages?
No. Metadata lives outside the visible pages. A name in a header, footer or signature stays until you edit or redact the page itself.
What is the Language field in PDF metadata?
It tags the document's main language, such as en-US, en-IN or hi. Screen readers use it to choose a voice and pronunciation, and accessibility checks often flag PDFs without it.
Can I edit metadata of a password-protected PDF?
Not directly. Remove the password with Unlock PDF first, edit the metadata here, then add a password again with Password Protect PDF if you need one.
Is my PDF uploaded when I edit its metadata?
No. pdf-lib reads and rewrites the file in your browser, and the new copy is created on your device. The page content is saved as it was.
