Edit PDF Metadata and Document Properties
Change the title, author, subject, keywords, creator, producer, or dates stored in a PDF. The pages and visible content stay the same.
How to edit PDF metadata - 3 steps
- 1
Upload the PDF
Add one PDF, up to 500 MB. The editor reads the document properties already in the file and shows the values it can edit.
- 2
Change the properties
Update the title, author, subject, keywords, creator, producer, or dates. Leave a field blank when it should not be included in the saved copy.
- 3
Save the updated PDF
Save the changes and download a new PDF. The page content stays in the document while its properties are rewritten in your browser.
What this PDF metadata editor changes
This tool changes document properties stored inside a PDF. It is useful when a file has the wrong title, carries an old author name, needs a subject or keyword list, or shows the name of the software that created it.
The editor supports the PDF title, author, subject, keywords, producer, creator, creation date, and modification date. It reads the existing values first, so you can correct a property without rebuilding the document from scratch.
Metadata is separate from the visible page content. Changing these fields does not rewrite the paragraphs, images, page count, layout, or text shown when the PDF is opened.
Supported PDFs and the 500 MB limit
The page accepts one PDF file at a time, with a maximum size of 500 MB. It does not accept Word files, images, or other formats directly; convert them to PDF first if that is the file you need to work on.
A large PDF can still use a good amount of browser memory while it is read and saved. If the file is near the limit or contains many high-resolution pages, keep the original and allow extra time for the browser to finish.
Password-protected or encrypted PDFs may not open if the editor cannot read them. The tool does not bypass a password or remove document security settings.
Which fields should you fill in?
Use Title for the name people should see in a PDF viewer or document list. Author identifies the person or organisation responsible for the document. Subject gives a short description, while Keywords can contain a few useful search terms separated by commas.
Creator and Producer normally describe the application or workflow that made the PDF. Change them only when the existing values are wrong or when your records require a different value. Creation and modification dates are available for correcting document history, but changing a date does not prove when the document was actually written.
What happens to the PDF after saving?
The editor creates a new PDF and updates its document properties. The visible pages, text, images, and page order are not intentionally changed by the metadata edit.
Because the file is saved again, do not treat it as a byte-for-byte copy of the original. Check important files after downloading them, especially if they contain forms, signatures, embedded files, annotations, or application-specific features.
The metadata you enter may be visible to anyone who receives the PDF and opens its document properties. If you want to remove properties instead of replacing them, use Remove PDF Metadata.
What this tool does not do
It does not edit the words or images on a page, redact sensitive text, flatten form fields, remove a password, or guarantee that every private detail has been removed. PDF metadata is only one place information can be stored.
For sensitive words or images, use Redact PDF. For form and annotation changes, use Flatten PDF. For a complete metadata cleanup before sharing, use Remove PDF Metadata and then inspect the result in a PDF reader.
Your files never leave your device
The PDF is read and rewritten in your browser. It is not uploaded to a server while you edit its document properties.
Most online PDF sites upload your document to their servers, process it there, and keep a copy for minutes, hours, or longer. PilotPDF works differently: the page downloads a small processing engine into your browser, and your file is opened and edited in your device's memory using WebAssembly. Nothing is transmitted, so there is nothing for a server to store, leak, or scan. You can even disconnect from the internet after the page loads and the tool keeps working.
