How to edit a PDF’s metadata, step by step

A PDF’s internal details — title, author, declared language — get corrected directly in your browser, without touching the page content.

  1. Drop in the PDF

    The existing metadata appears right away, with the page count, size, and producing software shown just above.

  2. Correct the text fields

    Title, Author, Subject, Keywords (comma-separated), and Creator can be edited or cleared. “Clear all” empties them all and, on save, also removes the producer, the dates and the XMP metadata.

  3. Set the two accessibility options

    The document’s language (read by screen readers) is picked from a list; “Show the title instead of the file name” makes the entered title appear in the PDF reader’s title bar instead of the file name.

  4. Click “Save metadata”

    The updated file downloads with the new values.

The producing software shown at the top cannot be edited, but “Clear all” removes it from the saved file; leaving the language empty writes nothing rather than a hollow value.

Frequently asked questions

How do you change a PDF’s title or author?

Open the file in the tool: the existing metadata (title, author, subject, keywords) is displayed and directly editable. Correct the fields you want, then download the updated PDF.

Can I erase the name of a piece of software or an author left in a PDF by accident?

Yes. Each field can be emptied, and the “Clear all” button empties the title, author, subject, keywords and creator in one go. On save, it also removes the producer, the creation and modification dates, any other entries and the XMP metadata stream that Word or Acrobat often add.

Does editing metadata require uploading the file online?

No, reading and writing metadata happens in your browser, with no transmission of the document to a third party, and the tool is free to use.

Which fields can be edited?

Title, author, subject, keywords and creator, plus the document’s declared language and the option that shows this title in the reader instead of the file name. The first five are the fields read by document search engines, libraries and most document management systems — a good reason to fill them properly before submitting a thesis or publishing a report.

Does the title a reader displays come from the file name?

Not always, and this is the most common confusion. Many readers show the internal “title” field, not the file name. A neatly named report can therefore open under the title of the Word template it came from, sometimes a previous client’s.

Is editing metadata enough to anonymise a document?

No. The visible fields are cleaned, but the page content stays as it is, and other traces may remain elsewhere in the file. To remove information from the text you have to redact it; to remove automation mechanisms you have to clean the file.
