NameChanger

NameChanger is a utility for Mac that streamlines the process of renaming multiple files in bulk. Users simply create a list of files and apply naming rules—such as find-and-replace, sequential numbering, case conversion, or custom patterns—all at once instead of renaming files individually. It's widely used by photographers, video editors, content creators, and anyone who regularly manages large batches of files that need consistent naming. The app works directly on your file system and includes features like undo support and the ability to preview changes before committing them.
