What Is A Creator?

The Creator field names who, or what, is responsible for the file. Sometimes it holds a person's name. Just as often it holds the name of the program that saved it.

Which files carry it, and where the value comes from

Documents such as PDFs, word processor files and spreadsheets carry it, and so do images, e-books, audio files and video files. It gets filled in three different ways: a person types a name into the file's properties, or the software copies in the name registered in it or in the account signed into it, or the program simply writes its own name.

What counts as the creator depends on the file. For an image it is the person who took the photo or drew the graphic. For a document it is whoever wrote the content, although documents and e-books more often use the author field for that. For an audio file it can be the producer or the person who made the recording, and it is sometimes used in place of the more usual artist or band field.

The exact wording of the row tells you which sort you are looking at. A plain Creator is normally a person or an organisation, while Creator Tool or Creator Software is an application. PDFs split it further: the creator is the program the document was originally written in, and the producer is the program that turned it into a PDF. The field can also hold more than one name, for a file with several photographers or authors.

What the value looks like

Free text, of one of three kinds:

• a person: Jane Doe
• a company, studio, agency or institution
• an application, for example Adobe Photoshop, Microsoft Word or GIMP, often with the operating system and a version number appended

Plenty of files leave it empty, and plenty of others hold a name that no longer has anything to do with the file's current contents.

Why it matters

This is one of the few metadata fields that names an actual human being, so it is a privacy field first. It is regularly filled with a full name that whoever typed it never expected to publish, and it survives every copy, upload and share. The two classic leaks are a document built from a colleague's template that still carries their name, and a photo carrying the name someone registered in a camera or an editing program years ago.

It also matters for credit. Picture desks, publishers and asset systems read this field for attribution. But the Creator is not automatically the owner: rights to creative or scientific work are often held by another person, a company or an institution, so treat the row as evidence of who made the file, not of who controls it.

Finally, the software entries are useful history. Knowing which application wrote a file often explains why it behaves the way it does, and helps you choose something that can open it. The field has no effect on quality, size or playback.
