Edit PDF Metadata

Every PDF can carry document-information metadata: a title, author, subject, keywords and the names of the creating application (creator) and PDF library (producer), plus creation and modification dates. Viewers and search tools read these fields, so they affect how your document is labelled and found.

Editing this metadata lets you set a clean title, fix an author name, add keywords for searchability, or clear fields that leak information. This editor reads and rewrites the fields entirely in your browser, so your PDF is never uploaded — and an empty field is saved as cleared, not stamped with our own details.

Metadata does real work once a PDF leaves your machine. Search engines often show a PDF's title field as the clickable headline in results, falling back to the filename when it is blank — which is how "draft_final_v3.pdf" ends up on page one. Reference managers pull title and author to build citations, and operating systems surface the same fields in file-property panels and search indexes. A minute spent filling them in pays off everywhere the file travels.

Keep in mind that metadata and page content are separate layers. Changing the title field does not rewrite the heading printed on page one, and a beautifully typeset cover page does nothing for the blank title a viewer shows in its tab — you set each independently. The same applies in reverse: renaming the file on disk never touches the embedded fields, so a sanitised filename can still carry an author name inside.
