What PDF metadata is
Besides its pages, every PDF can carry a small set of document properties. You rarely see them, but they appear in your reader's properties window, in search results and sometimes as the title of the browser tab when the file is opened online. This page shows all of them and lets you change each one.
| Field | What it usually holds |
|---|---|
| Title | The document's name. Many readers show it instead of the file name. |
| Author | Often filled in automatically from the account name of the computer that made the file. |
| Subject and Keywords | A short description and search words, used by document libraries and some search engines. |
| Created with and PDF made by | The app that created the document and the software that produced the PDF. |
| Created on and Last changed on | Dates, which may reveal more about a document's history than you intended. |
Next to the form you'll also see read-only facts: number of pages, PDF version, file size and the size of the first page in millimeters and inches, with its paper name when it matches A4, Letter or another common size.
Reasons to edit it
- A proper title. A report exported as “Microsoft Word - draft_v7_final” looks careless when a client opens it. Set a clean title before you send it out.
- Correct authorship. Replace a former employee's name or a generic account name with your company or your own name.
- Better findability. A descriptive title and subject help when PDFs are published on a website or stored in a document system.
- Privacy. Author names, software versions and exact creation times can reveal who made a file and when. Use Remove all metadata before you share something anonymously.
What Remove all metadata clears
It empties every field in the document information, including custom entries some apps add, and deletes the separate XMP metadata block that many PDFs also contain. XMP is a second copy of the same details in another format, and some readers prefer it, which is why editing only the visible fields isn't always enough. When you save changes to individual fields, the XMP copy is removed too, so every reader shows your new values.
Only the properties change. Pages, text, images, links and form fields stay exactly as they were. Metadata is not the only place personal details hide, though. Names inside the page text, comments or scanned signatures need Redact PDF.
Works on your device
The file is read and saved inside your browser without being uploaded. PDFs that only have printing or copying limits can be edited directly; a file that needs a password to open must be unlocked first with Unlock PDF.
Frequently asked questions
Does changing metadata change how the pages look?
No. Only the document properties are rewritten. The pages, text and images are copied exactly as they were.
Why does my PDF reader still show the old title?
Some readers cache file information. Close the file and open the downloaded copy, not the original. If the original had an XMP block with the old title, this tool removes it when you save, so the new title is the only one left.
What does Remove all metadata leave behind?
The pages and their content. Every document information field and the XMP block are removed, and no new software name is added when the file is saved.
Can I set the dates to anything I want?
Yes. Pick a new date and time, or clear the field to remove the date entirely. Times are entered in your local time zone.
Is my PDF uploaded to read the metadata?
No. The file is opened and saved in your browser, and nothing is sent anywhere.
