Name Mangler
Name Mangler is a Mac batch file renaming utility that helps you rename large groups of files quickly with reusable rules and previews.
What is Name Mangler?
Name Mangler is a native macOS utility for renaming large groups of files in a fast, controlled way. It is designed for people who regularly manage photos, media, downloads, documents, or project files and want more flexibility than Finder’s basic rename tools. The app lets you build single-step or multi-step renaming actions, preview the results before committing changes, and save presets for repeated jobs. It can work with text replacement, sequence numbering, case changes, and metadata-based naming for supported files. Name Mangler also supports advanced patterns for users who need more precise control over naming rules. Published by Many Tricks, it fits well into Mac workflows where consistent file names make sorting, archiving, and sharing easier.

Safety overview
Status: Safe
Name Mangler is legitimate file management software for macOS. It needs access to the files and folders you choose so it can rename them, which is normal for a batch renaming tool. The main practical risk is accidental renaming if a rule is too broad, so it is best to review the preview carefully before applying changes to important files or shared folders.
Recommendation: Keep Name Mangler if you regularly rename groups of files or rely on saved rename presets in your workflow. If you no longer use it, removing it is usually fine, but any saved presets or app-specific settings may be lost unless you back them up first.
