How to Batch Rename Files on Mac

To batch rename files on a Mac, select them in Finder, right-click and choose Rename. You can replace text, add text, or apply a name and counter format. Check the example shown before you confirm. For rules based on dates, numbers or content, use Shortcuts or a dedicated renamer with an undo.

Finder's Rename for many items

Select the files, right-click, and choose Rename. Pick Replace Text, Add Text or Format. The dialog shows an example of the first new name. It is enough for sequential numbering and simple find-and-replace.

When you need more rules

Dates from the file, zero-padded numbers, case changes, or names built from content need more than Finder offers. A Shortcut can chain Rename actions, and a dedicated renamer can show a full before-and-after list.

How Paperlane for Mac approaches it

Paperlane for Mac is a free native macOS app that renames batches of files on your Mac. Batch Rename shows a preview first: every old name next to its new name, with clashes flagged, and nothing changes until you apply it. An undo journal can reverse the batch. Pattern renaming works on any supported Mac; Apple Intelligence suggestions need macOS 26.

Limits

Renaming cannot be perfect on messy names: look through the preview before applying. Apple Intelligence suggestions depend on the text the file contains and may be wrong.
