NameChanger
What it is
NameChanger is a free macOS app for renaming lists of files while previewing resulting names as changes are entered. It provides replacement text, wildcards, prefixes and suffixes, dates, sequences, character removal, regular expressions, and case changes. Files can be added through the interface or by dragging them into the app, and directories can be scanned recursively. The app keeps a history of renames and offers controls to hide extensions, ignore case, and force unique resulting names. Its Image Browser supports visual naming and reordering of pictures. Finder users can select files and invoke NameChanger through the Services menu. The listed current release is version 3.4.4, a Universal Build for OS X 10.13 and later; earlier versions are listed for older OS X releases. 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.
