Does renaming change anything inside the PDF?

No. The bytes are exactly the same; only the file name is new. That matters for signed documents: re-saving a signed PDF can break its signature, and this never re-saves.

What if two files end up with the same name?

The second one gets -2, the third -3, and so on — nothing is overwritten inside the ZIP. Add {n} to the pattern and every name is unique from the start.

Where does {title} come from?

From the title field inside the PDF — the one a reader shows in its tab or window title. Many scans have none; for those the current file name is used instead.

How to do it

Add your file

Download the result
Download the renamed files. With more than one file they arrive together in a single ZIP.
