PDF Metadata Editor

To edit PDF properties, add the file, change the title, author, subject, keywords or dates, or press Clear all to empty them, then save. Removing the XMP metadata stream stops old values showing in some viewers. Pages, fonts and images are untouched, and the saved values are read back so you can check them. Nothing is uploaded.

How to use the PDF Metadata Editor

  1. 1Add a PDF — its current properties are filled in.
  2. 2Edit any field, or press Clear all to empty them.
  3. 3Choose whether to remove the XMP metadata stream.
  4. 4Save, check the values read back from the new file, and download it.

How it works

PDF properties live in the document information dictionary: fields for the title, author, subject and keywords, the application that created the document, the software that produced the PDF, and when it was created and last modified. Search engines and document systems read them, and the title is what many PDF viewers show in the window bar instead of the file name.

Many PDFs also carry a second copy of this information as an XMP metadata stream, and some readers prefer that copy. Changing the title here while an old XMP stream stays behind can leave different programs showing different titles. Removing the XMP stream makes the fields you set the only metadata the file contains.

Only the properties are rewritten; pages, fonts, images and bookmarks are carried over unchanged. Empty fields are removed from the file rather than saved as blanks. After saving, the new file is opened again and its properties are read back, so what you see is what the file really contains.

The file is read into your browser's memory, changed there, and handed straight back to you. Nothing is uploaded, so there is no queue and no copy sitting on a server afterwards.

Tips and common mistakes

  • Check the properties before a PDF leaves your organisation. The author field often holds a full name or a computer username, and the title can be an old working title nobody meant to publish.
  • Give PDFs you publish a clear title. Many viewers show it in the window bar instead of the file name.
  • Leave “Remove the XMP metadata stream” ticked when you change the title, so different programs do not show different titles.
  • Edit the metadata as the last step. Other PDF tools often rewrite the producer field and the modified date when they save, which can undo your changes.

Frequently asked questions

Why does my PDF viewer still show the old title?
Some viewers read the XMP copy first. Save again with “Remove the XMP metadata stream” ticked, then close and reopen the file in case the viewer cached it.
Can I remove all metadata before sharing a PDF?
Press Clear all, keep “Remove the XMP metadata stream” ticked, and save. The document properties and the XMP stream are removed. Other content — comments, form data, or text inside the pages themselves — is not affected.
Does editing metadata change the document's content?
No. The pages are copied as they are; only the properties change.
Why can't I edit an encrypted PDF?
Encryption locks the file's structure, including its properties. Remove the password in a PDF reader you trust, then edit the properties here.
What are the creator and producer fields?
The creator is the application the document was written in, such as a word processor. The producer is the software that turned it into a PDF. Both are set automatically and can reveal which programs you use.
Can I change the creation and modification dates?
Yes. The dates are editable fields like the others, and clearing them removes them from the file instead of saving blank values.
Do search engines read PDF metadata?
They can. For a PDF published on a website, the title property is one of the things a search engine may use when it lists the file, alongside the text of the document itself.
