What NameChanger is
NameChanger is a free macOS app for renaming groups of files, with a preview that updates as you type. You can replace text, use wildcards, add prefixes or suffixes, insert dates or sequences, remove characters, apply regular expressions, and change letter case. Files can be added in the app or dragged in, and NameChanger can scan a directory and its subfolders recursively. It keeps a history of completed renames. Extra controls let you hide extensions, ignore case, or make output names unique. The Image Browser supports visual naming and reordering of pictures, and Finder users can select files and launch the app from Services. The listed current release is version 3.4.4, a Universal Build for OS X 10.13 and later; the page also lists releases for older OS X versions. The Free plan is free and allows personal, commercial, non-profit, and educational use, with unlimited installations and copies. The EULA provides the software as is without express or implied warranties.
