How do I write the author?

Put a vertical bar after the title and type the author, like Invoice 2026 | Jane Doe. The author part is optional.

Where do the details show up?

In the file properties of a PDF reader, and in the title of a browser tab that shows the file.

Yes. The remove metadata tool takes them all out in one go.

Give a PDF the title and the author it should carry, so it sorts and searches properly.

Drag & drop a PDF, or choose it from your device. It stays on your machine.
