Edit PDF Metadata

Check document details before sharing

A PDF can carry information that never appears on its pages. A report may still name the person who drafted a template, a customer from an earlier project, or an internal working title. Those details can appear in a reader's document properties, a search result, or a document management system. Before sending a file outside your team, check whether its description matches the document you actually intend to share. Editing these details gives the file a useful identity without changing the words, images or layout that a reader sees on the page.

The title is the document's descriptive name, which can differ from its filename. The author identifies the person or organisation responsible for the work; it does not prove who wrote or approved it. The subject is a short description of the document's purpose. Keywords are terms that help people find and sort the file. Enter them separated by commas. A clear title and a few relevant keywords can be helpful in a shared archive, while an outdated author or subject can cause confusion. Leave a field empty when there is no useful information to put in it.

Creator and Producer describe how the file was made. Creator usually names the application used to prepare the original document, while Producer usually names the software that wrote the PDF. They may reveal an internal workflow, but they are ordinary descriptive fields rather than a reliable audit trail. Created and Modified are document timestamps, not the dates shown in your computer's file manager. The form shows them in your local time zone. They stay read-only until you turn on Change dates. Changing a timestamp does not establish when the underlying work was completed or make a document authentic.

Many PDFs store the same description in two places: a document information dictionary and an XMP metadata packet. Different readers may prefer different copies. This tool reads both and keeps the supported fields in step when you save, so changing the author does not leave the old author in the other copy. If the file has no XMP packet, saving changes writes the information dictionary without adding a new packet. Existing XMP properties outside the supported fields stay in place. After saving, compare the Before and After columns and download the edited copy. Your original file is left untouched.

Remove all metadata clears every entry in the document information dictionary, removes the document's XMP packet and removes application-specific PieceInfo from the document and its pages. Unreferenced objects containing those old details are discarded from the saved copy as well. This action does not erase page text, pictures, comments, form entries, bookmarks or links. A name printed on a page will still be there, and an attachment may contain its own information. Removing document metadata is therefore a useful sharing step, but it is not a substitute for reviewing the visible content or redacting confidential material.

The file is read and changed in your browser; its contents are not uploaded. The usual file and page limits still apply. Unlock a password-protected PDF before opening it here. If the file carries a digital signature, changing even a descriptive field rewrites the signed file and breaks that signature. The tool warns you and requires a second click on Change anyway before making the edited copy. Keep the original signed document when its signature matters. Finally, reopen the download in your usual reader and check its properties and pages before sharing it with someone else.
