About this tool
Every PDF carries a small block of document metadata alongside its pages — Title, Author, Subject and Keywords fields that file managers, search engines and PDF readers show in "Document Properties", plus Producer/Creator strings left behind by whatever software generated the file. That metadata often leaks more than intended: a title copied from an internal project code name, an author field with someone's full account name, or keywords from an old draft. This tool reads all of it straight out of the file you choose, lets you edit any field in place, and re-saves a new PDF with your changes — entirely in your browser, with nothing ever uploaded.
Editing is non-destructive to everything else in the document: only the metadata fields you actually change are touched, so the pages, fonts, images, links and form fields inside the PDF are left exactly as they were. Clear a field entirely by emptying its box before saving, or leave a field untouched to keep its original value. Creation and modification timestamps and the page count are shown for reference but are not user-editable here, since most PDF workflows treat them as provenance rather than something to hand-edit.
Frequently asked questions
Why would I want to edit a PDF's metadata?
Common reasons: setting a proper Title so the document shows a meaningful name (not a filename) when opened in a browser tab or PDF reader, adding an Author/Keywords for better searchability in document management systems, or removing personal/identifying details (like a real author name or the software that generated it) before sharing a file externally.
Does changing metadata affect the visible content of the PDF?
No — metadata (Title, Author, Subject, Keywords, etc.) is separate from the visible page content. Editing it only changes what shows up in "Document Properties" and similar info panels; the pages themselves, their text, images and layout, remain completely untouched.
