How to Rename Multiple Files at Once on Mac
Rename many files at once on Mac using text replacement, prefixes, suffixes, automatic numbering and extension changes — and see how JoyClick adds a live-preview batch rename tool to the right-click menu.
Short answer: To rename multiple files at once on Mac, select the files and apply a consistent naming rule. JoyClick provides batch rename actions directly from the right-click menu, including text replacement, prefixes, suffixes, numbering and extension changes, with a live preview.
Why this happens
- Renaming files one by one does not scale beyond a handful of files.
- Photos, scans and downloads often arrive with inconsistent names.
- Manual renaming is slow and easy to get wrong across a large selection.
How to do it without extra tools
- Use Finder’s built-in Rename command (right-click a selection, then Rename Items) for simple patterns.
- Rename files individually if the naming rule differs per file.
- Use a shell loop with a command such as "mv" for advanced cases.
How JoyClick helps
JoyClick adds a Batch Rename tool to the right-click menu. It supports text replacement, prefixes, suffixes, automatic numbering and extension changes, and shows a live preview so you can confirm the result before applying it.
