NameChanger

What NameChanger is

NameChanger is a macOS app for renaming groups of files, with a preview that updates as you adjust the proposed names. You can add files through the interface or drag them into the app, and it can recursively add files from a directory structure. Rename operations include replacing text, using wildcards, adding text before or after names, inserting dates or sequences, removing characters, applying regular expressions, and changing case. Options can hide file extensions, ignore case, or force resulting names to be unique. An automatically kept history records renames, while the Image Browser supports visual naming and reordering of pictures. You can also invoke NameChanger as a System Service by selecting files in Finder and choosing Services > Rename with NameChanger. The listed current version is 3.4.4, a Universal Build for OS X 10.13 and later; previous versions are listed for older OS X releases, including OS X 10.3. The Free plan costs nothing and covers personal, commercial, non-profit, and educational use, with unlimited installations and copies. The EULA provides the software as is without express or implied warranties.

Who it suits

NameChanger suits macOS users who need to rename batches of files with a choice of text, pattern, date, sequence, or case-based operations. It may also suit people organizing pictures visually or starting a rename from Finder.
