Frequently asked questions

What is PDF metadata?

The document properties stored inside the file — Title, Author, Subject, Keywords, and Creator. They show up in a PDF reader’s "Document Properties", in file managers, and in search results, and help organise and identify a document.

Why set the title and keywords?

A clear Title is what many readers and search tools display instead of the filename, and Keywords aid searchability in document systems. Setting them makes a PDF look professional and easier to find.

Do blank fields keep the old value?

No — a field left blank is written as empty. After processing, the tool shows the previous values it could read, so you can re-run and re-enter anything you want to keep.

Does it change the page content?

No. Only the document properties are written; the pages themselves are imported unchanged.

Will it work on an encrypted PDF?

No. Password-protected files cannot be rewritten; remove the protection first. Files are processed on the server only to build the result, and the temporary copies are cleared automatically a short time later.

About the PDF Metadata Editor

This tool sets the document properties — the metadata — stored inside a PDF: its Title, Author, Subject, Keywords, and Creator. These are the details a PDF reader shows under "Document Properties", that file managers and search tools index, and that often appear in place of the raw filename, so getting them right makes a document look professional and easier to find.

Why metadata is worth setting

Most PDFs in the wild have empty or junk metadata — a "Title" left as "Microsoft Word - draft3.docx", or no author at all. That is a missed opportunity. A proper Title is frequently what gets displayed in browser tabs, reader windows, and even search results, so a clean one immediately reads better than a filename. Keywords and Subject help document-management systems and site search surface the file for the right queries, and a sensible Author and Creator make provenance clear. For anyone publishing PDFs — reports, whitepapers, guides — tidy metadata is a small, cheap SEO and professionalism win.

How it works

Enter the properties you want, upload the PDF, and the tool imports every page unchanged and writes your values into the document’s information dictionary, producing a new PDF. Only the metadata is altered — the visible page content is untouched. One thing to know: a field left blank is written as empty rather than preserving whatever was there before, so after processing the tool shows you the previous values it was able to read from the file, letting you run it again and re-enter anything you intended to keep.

Notes and privacy

The PDF must not be encrypted or password-protected. Files are processed on the server only to build the result, and the temporary copies are cleared automatically a short time later. To stamp visible titles and page numbers onto the pages themselves, use the Add Header and Footer to PDF tool.
