Bulk Image Renamer
Re-export with a name pattern such as photo-001.jpg. Does not rewrite pixels unless you change format.
Bulk Image Renamer is its own job in the catalog (utilities): Re-export with a name pattern such as photo-001.jpg. Does not rewrite pixels unless you change format. It is not a copy of the resizer or converter with a new title — the operation is “rename”.
